Discussion of these concerns is hampered by ongoing Available online 8 November 2015 disagreement about the true trajectory of academic performance at the basic education level and the Keywords: widespread nature of students’ lagging academic performance. In part, this disagreement stems from the Academic achievement failure of empirical studies to comprehensively examine trends in academic performance standards at the Spatial modeling basic education level by concurrently considering a geographical and longitudinal perspective. Thus, this Multilevel growth curve modeling study examines the spatio-temporal trends of academic performance at the junior high school level since Educational inequalities 2009 by using multilevel growth curve modeling, spatial statistics, and district-level longitudinal data. Ghana Results reveal 3 statistically distinct trajectories of academic performance: erratic, accelerating, and de- celerating changes. Results also show that rural–urban gaps explain 31% of the performance trajectories, a trend which is expected to persist in the long term. In addition, we find extreme variations in academic performance within rural areas. Given the varying trajectories and geographical variability in academic performance, we suggest a localized approach to addressing challenges of low academic achievement at the basic education level in Ghana. © 2015 Elsevier Ltd.

Introduction Since the late 1980s, Ghana has substantially expanded its ed- cational system and steadily increased investment in education Akyeampong, Djangmah, Oduro, Seidu, & Hunt, 2007). Public ex- enditure on education as a share of the country’s gross domes- ic product (GDP) increased more than 600% from 1.8% in 1980 o 8.14% in 2011, which is well above the current average of 5% DP for Sub-Saharan Africa (UNESCO, 2015). Ghana also embarked n implementing major educational policies and programs, includ- ng the free Compulsory Universal Basic Education (fCUBE) policy, apitation Grant, and the School Feeding Program.

These investments have sought to rovide all Ghanaian children with basic education, putting Ghana ell on track to achieving its goal of universal access to basic ed- cation. This goal is also consistent with the international com- unity’s cross-thematic development frameworks such as the Mil- ennium Development Goals (MDGs) and Sustainable Development oals (SDGs). MDG Goal 2 seeks to ensure that by 2015, all chil- ren will be able to complete primary level schooling without re- pect to their gender or the area or region in which they live. Sim- larly, the SDGs push for inclusive and quality education for all United Nations Economic Commission for Africa [UNECA], 2013). learly, the improved access to basic education in Ghana is com- 2 D.

Despite the goal of the fCUBE policy to improve the access and quality of basic education, improvements in learning outcomes at this level have not kept pace with the remarkable improvement in access (Darvas & Balwanz, 2014; Mettle-Nunoo & Hilditch, 2000). Although stakeholders generally agree that academic performance standards at the basic education level are low and of great concern (Affum-Osei, Asante, & Forkuoh, 2014; Gyan, Mabefam, & Baffoe, 2014), they disagree on the true trajectory of learning outcomes. This issue is clouded by inconsistent claims about whether perfor- mance standards are falling, rising, or unchanged. The lack of clar- ity on the true trajectory of primary level academic achievement is due to, at least in part, most of the assertions being based on snip- pets of results rather than comprehensive nationwide longitudinal data. Many in Ghana share the perception that academic achieve- ment is falling (Degue, 2012; Okyerefo, Fiaveh, & Lamptey, 2011). In particular, this perception becomes heightened each year with the release of the annual Basic Education Certificate Examination (BECE) results. BECE is the national standardized examination for students who have completed junior high school (JHS) (i.e., Grade 9). The heightened perception of falling academic achievement is in part because, for instance, 182,000 JHS candidates who sat for the 2013 BECE did not earn a passing grade for at least one core subject, and therefore, did not qualify to enter senior high school. Importantly, some analysts have described this shared perception of a downward trend in academic achievement as a national secu- rity threat (Gyasiwaa, 2013). Many of those who contend that academic achievement is falling have also speculated that the expanded enrollment in the basic education level has come at the cost of the quality of basic education. As noted by Lewin and Akyeampong (2009), “… rapid expansion in enrollments has degraded quality” (p.143). Similarly, the United Nation’s 2014 MDG report asserted that Ghana’s ex- panded access to education has steadily weakened the quality of education, and linked the decline in educational quality and stu- dent achievement to larger class sizes, the growing number of new schools, and the government’s heavy reliance on poorly trained and unqualified teachers (UNECA, 2014). However, significant increase in educational investments does not necessarily have to lead to a trade-off between enrollment (quantity) and learning outcomes (quality). Indeed, data from the late 1980s to the early 2000s sup- port the idea that Ghana’s massive investment in education sector in the form of 8000 classroom blocks led to concurrent improve- ments in enrollment and students’ learning outcomes. Why then is there perception that Ghanaian students are on a downward slope of academic achievement? Simultaneously, many other stakeholders disagree with the as- sertion that Ghanaian students’ academic performance is falling. For instance, even the chief examiners’ report of the 2012 BECE suggests that performance trends were mixed (West African Ex- amination Council, n.d.). Other experts and educational scholars contend that the perception of falling performance is false and, not based on data. For instance, Francis Kodzo Amedahe, a pro- fessor in educational measurement and statistics at the University of Cape Coast, has contended that “… the issue of falling educa- tional standards in Ghana is a perception rather than a reality” (Ghana News Agency, 2014; para.1). Given conflicting viewpoints on the academic performance trajectory of Ghana, there are impor- tant empirical questions that warrant attention. The most pressing unanswered questions include: (a) What are the factual trajectories of academic performance standards at the basic education level? (b) Are the academic performance trajectories generally consistent across Ghana’s administrative districts, and are there salient spatial variations in the direction and rate of change in academic perfor-ance? This study aims to help fill this empirical gap in academic per- ormance through systematic assessment of the spatio-temporal ynamics of academic achievement in Ghana at the BECE level. e examine 6 years’ of local and nationwide BECE data (collected rom 2009 through 2014) to address fundamental questions on hether (a) statistically significant trends exist in academic per- ormance, (b) such trends are sloping upwards or downwards, and c) whether these trends, if any, favor or disadvantage certain ge- graphical areas of the country. Developing a better understand- ng of the space-time trends of academic achievement in Ghana is ritical because determination of the spatial trajectory of academic erformance (and potential disparities) in the country will enable ducation researchers, administrators, and policy makers to better arget their energies to areas in need of attention, especially at the asic education level. . Rural–urban differences Spatial inequality in Ghana is not a new phenomenon. How- ver, concerns are growing among many scholars and practitioners hat the extent of spatial inequality in education and other social ndicators is widening despite the country’s economic growth, in- estment in socioeconomic development, and falling poverty lev- ls (Annim, Mariwah, & Sebu, 2012; Aryeetey, Owusu, & Men- ah, 2009). Like many sub-Saharan African countries (Michaelowa, 004), significant rural–urban differences exist in Ghana in terms f access to educational resources and the resultant outcomes of hese resources. More often than not, the rural–urban gaps in ed- cational outcomes favor urban areas because they have dispro- ortionally more education resources (e.g., good classrooms and chool furniture) and favorable living conditions such as good oad and accommodation (Ansong, Ansong, Ampomah, & Adjabeng, 015; Kimosop, Otiso, & Ye, 2015; Senadza, 2012). Despite the urban advantage, the caveat is that the rural–urban ifferences may not always be a clear dichotomy. The educational iscourses in Ghana often presume that the problem of spatial dis- arities in educational outcomes is more acute in rural than urban reas (Tsikata & Seini, 2004). However, in the absence of adequate mpirical evidence from a contextualized and spatial perspective, his presumption may be an over-simplification of the problem. lthough a great deal is known about rural–urban inequalities re- arding access to education and related resources, little is known bout these inequalities in terms of specific educational outcomes e.g., academic performance) given the scant nationwide empirical ssessment of any such potential spatial disparities. Empirical stud- es are yet to clarify the temporal nature of academic performance n rural versus urban areas. One of the few studies to have exam- ned the spatial dimension of learning outcomes used data from random sample of 6000 junior high-school students from across hana (Ansong & Chowa, 2013). The study found regional varia- ions in educational performance when measured by math and En- lish scores, but such variations favored predominantly rural areas uch as the western and northern regions. However, because the tudy focused on limited subject areas (i.e., only math and English ubjects) and used cross-sectional data, its findings do not offer a olistic overview of the country’s space-time trends in academic erformance. The absence of such a holistic overview is not unusual, and he data used to shape conversations on growing spatial inequal- ty are often incomprehensive, non-longitudinal, and inadequately crutinized. To a large extent, public concerns about falling aca- emic standards at the basic education level have been driven by edia reports of the abysmal BECE performance of primary level tudents. Although these reports are important in initiating con- ersations about measures for addressing inequalities in learning D.

For instance, in 2012, media reports claimed hat more than two-thirds of the 840 candidates who sat for the ECE in the Sissala West District failed the exam (Farouq, 2012). he Ghana News Agency (2010) also reported that not a single can- idate from more than a dozen public and private schools in the gona West Municipality scored high enough (i.e., aggregate scores to 30) on the 2012 BECE examination to qualify for placement in second-cycle institution (i.e., senior high, vocational, and techni- al schools). While such media reports focus on select schools or chool districts, they tend to skew public perception of the state of asic education performance in Ghana. From a policy and research tandpoint, it is critical to assess empirically whether the problem f low academic performance of the BECE is ubiquitous in Ghana r is confined to specific schools and regions. Thus far, given what is known about educational outcomes by ocation, enrollment, and educational progression, there is reason o believe that substantial spatial variations exist in district-level rajectories of academic performance. For instance, Akyeampong t al. (2007) found that the education system favors students living n urban districts. Specifically, Akyeampong and colleagues, found hildren from urban areas were not only more likely than rural hildren to pass the BECE and transition to senior high school, ut that the rural–urban gap in school enrollment and progres- ion was widening. Moreover, the rural–urban gap also manifests n other ways that can affect educational outcomes. For example, he disparity in the “educational climate” between rural and ur- an areas was revealed by the 2010 Population and Housing Cen- us, which showed that whereas 1 out of 7 urban residents had ever attended school, that proportion was significantly higher in ural areas at 1 out of 3 (Ghana Statistical Service, 2012). Further ural–urban disparities exist in the quality of available school fa- ilities and education offered. Thus, rural residents’ access to qual- ty education is severely limited by poor infrastructure and the low umbers of qualified teachers (Poku-Boansi & Amoako, 2014). Rural chools often have inadequate classrooms, outdated or insufficient umbers of textbooks, and poorly trained or untrained teachers— ll of which exacerbate the relatively poor quality of education in hese areas (Ansong et al., 2015; Atuahene & Owusu-Ansah, 2013). ecause the Ghanaian society is socially, culturally, and economi- ally heterogeneous (Avendal, 2011), it is reasonable to assume that cademic performance trajectories vary across the country. How- ver, compared to existing knowledge on access to education and ducational resources in Ghana, little is known about spatial vari- tions in academic performance. . Inter-rural differences Inter-rural variability (i.e., variations between rural areas) is largely unexplored spatial dimension of rural deprivation in hana. Historically, the rural–urban dichotomy has been empha- ized in development theory and practice (Gough, Agergaard, Fold, Moller-Jensen, 2009). However, even though rural Ghana is dis- roportionately disadvantaged and has lower achievement out- omes, the dynamics of rural deprivation and the associated learn- ng outcomes are more intricate and nuanced than portrayed by he traditional rural–urban divide literature. Further, the lack of nderstanding of variability among rural areas has been perpet- ated by the many research studies on rural Ghana that have ag- regated all rural areas into a homogeneous category (Atuahene & wusu-Ansah, 2013; Mettle-Nunoo & Hilditch, 2000). The vast literature on rural challenges in Ghana notwithstand- ng, questions remain about whether educational disadvantage in ural areas is more acute in certain regions than others. Although ural Ghana shares many qualities, it also varies considerably in the ype and extent of deprivation experienced. For instance, most in-icators of human development (e.g., health, education, economic ell-being) suggest that the three northern regions of Ghana have more severe level of deprivation than either the middle or south- rn regions (Otiso & Owusu, 2008; Seini, 2000). Given these re- ional disparities and the structure of the educational system, ith rural districts nested within regions, a particularly challeng- ng question remains to be answered: Compared with the mid- le and southern regions of Ghana, do distinct clusters of low- erforming rural districts exist in the north? If so, how have these lusters evolved and changed over time and space? While it may e reasonable to infer that all rural areas are disadvantaged, espe- ially those in the northern regions (Poku-Boansi & Amoako, 2014), ew empirical analyses have been conducted on national space- ime trends in academic performance. Thus, it is unclear whether, cademic trajectories of the northern regions are unique or simi- ar to those of the nation as a whole. To help fill this knowledge ap, this paper uses multilevel growth curve modeling and spatial nalysis to examine, (a) the 6-year (2009–2014) trajectory of aca- emic achievement as measured by performance on the national unior high school examinations; (b) whether any such academic chievement trajectory is influenced by the rural/urban status of he district, and if so, how such influence is manifested; and (c) hether inequalities exist among rural districts in Ghana. The ben- fit of combining multilevel growth curve modeling with spatial nalysis in this study is the ability to measure change over time n the BECE results at both the national and district levels and at he same time geographically visualize the changes over time and ariations across different areas of the country. . Methods .1. Data and analyses The present study uses six waves of data (2009–2014) drawn rom the BECE results of junior high school students in Ghana. hese longitudinal data are aggregated at the school district level ith varying sample sizes: 142 districts in 2009, 138 in 2010, 154 n 2011, 156 in 2012, 169 in 2013 and 166 in 2014. These sample izes vary by year because of the creation of new districts during he study period and non-availability of BECE data from a few dis- ricts in 2010. Using two rigorous approaches— multilevel growth urve modeling and spatial statistics analysis–the data were exam- ned to determine the spatio-temporal curves of BECE pass rates in hana. .1.1. Multilevel growth curve modeling The use of repeated measures data make multilevel growth urve models an invaluable statistical tool in educational research ecause this technique estimates changes in student outcomes ore accurately by taking into account the hierarchical nature of he data (i.e., nesting of repeated measures within individual units) Hox & Stoel, 2005). Moreover, as compared with traditional ap- roaches for analysis of longitudinal data, multilevel growth curve odeling offers the advantage of being able to easily and effi- iently handle unbalanced data, such as the varying sample sizes n our data (Luke, 2004). We used multilevel growth curve mod- ling to model the process of change in BECE pass rates over ime, and to assess rural and urban differences in the initial sta- us and growth rates. The time variable is the academic year (Year), hich indicates the measurement occasion for each of the six BECE esults starting from 2009. The variable academic achievement is easured as the percentage of candidates who earned an aggre- ated score between 6 and 30, which is considered a passing score or admission to a senior high school (Mereku, 2012). To test for ural–urban variation in BECE pass rates, we included a binary easure of whether a district is predominantly rural or urban. 4 D.

The figure depicts a nonlinear growth curve; the percentage of candidates passing the BECE de- creased from 2009 to 2010 and then increased between 2010 and 2012 before decreasing again between 2012 and 2014. Because of these nonlinear trends in BECE results over time as shown in Fig. 1, we modeled quadratic (Year2) and cubic slopes (Years3) (Shek & Ma, 2011) to account for potential nonlinear individual growth tra- jectories in the way in which districts in Ghana perform at the BECE over time. Based on the recommended analytical strategy for longitudinal data analysis (Singer & Willett, 2003) we tested five nested mod- els, starting with the most restrictive and progressing to the least restrictive model. Model 1, the unconditional means model, exam- ined possible differences across all districts in the mean percentage of candidates who passed the exam, regardless of the exam year. This model also assessed average district level variations in the BECE pass rate and the amount of variance accounted for by the inter-district differences as well as differences between years. The intra-class correlation (ICC) was .49 [i.e., 208.06/(208.06 + 215.87) see Table 1], suggesting that inter-district differences explained 49% of the variability in the BECE pass rate. The ICC is greater than the recommended cutoff of .25, which further supports the need to use individual growth curve modeling (Kreft, 1996). Next, we modeled an unconditional linear growth curve model (Model 2) to examine the existence of any significant differences in the districts’ trajectory over time. Because the time variable was statistically significant in Model 2 (i.e., the baseline model) we pro- ceeded to examine two higher-order change trajectories. First, we added a quadratic term (Year2) to test for higher-order change tra- jectories over time. The resulting model (Model 3) was needed to examine whether the individual rate of change accelerated or de- celerated over time. In the next test for higher-order change trajec- tory (Model 4) we added a cubic term (Year3) to capture the rate of acceleration or deceleration over a long period of time. Model 5, the last in the five-step modeling process, tested the potential moderation role of a district’s status as either predominantly ru- ral or urban. In other words, this model tested whether the change trajectories were statistically the same for rural and urban districts. Because we did not expect the rural–urban designation of districts to change significantly over the observation period, we examined the rural–urban status as a time-invariant phenomenon. The model is estimated as follows: Yij = γ 00 + γ 01(Rural)j + γ 10(Year)ij + γ 11(Rural)j(Year)ij + γ 20(Year2)ij + γ 21(Rural)j(Year2)ij + γ 30(Year3)ij + γ 331(Rural)j(Year )ij + u1j(Year)ij + u0j + rij where Yij is the BECE pass rate of year i for district j, γ00 is the adjusted average BECE rate across all districts, γ 01 to γ 31 are thed t t r t t t a t t t a m t Fig. 1.

To determine which model best fits the data, we compared the t indices (−2 log likelihood [−2LL] and the Akaike information riterion [AIC]) of the two models with the lowest AIC values, that s, the cubic growth (Model 4) and predictor effect models (Model ) (Kuha, 2004; Shek & Ma, 2011). A pairwise comparison indicated statistically significant difference between the two models: χ2 4) = 7434.42–7412.63 = 21.79, p < .001. The AIC difference be- ween the lowest AIC model (predictor effect model AIC = 7436.63) nd all other models (unconditional linear growth curve, Model 2 IC = 7651.19; quadratic growth curve Model 3 AIC = 7493.28; cu- ic growth curve Model 4 AIC = 7450.42) were greater than the ecommended cutoff of 10 (Burnham & Anderson, 2002). This AIC ifference means that among all the nested models, only the pre- ictor effect model (Model 5) explained any substantial variation n the data. Thus, Model 5 (predictor effect) was retained as the nal and best fitting model. .1.2. Spatial pattern analysis Spatial pattern analysis was the second analytical approach we sed to examine the data. This method is a nontraditional statisti- al tool for mapping and quantifying statistically significant trends nd clusters in geographically referenced data. Specifically, we gen- rated thematic maps and conducted grouping analyses. The bene- ts of the spatial analyses include the ability to (a) validate results rom the multilevel growth curve models, (b) map and visualize dentifiable growth trajectories, and (c) highlight inter-rural, inter- rban, and rural–urban variations. First, we used the Grouping Analysis tool, a relatively new ex- loratory method in ArcGIS, to identify distinct groups of districts ased on the trajectories of the BECE pass rate. To avoid pre- udging the number of distinct trajectories, we used the Calinski– arabasz pseudo F-statistic to determine the maximum number of eographically diverse trajectories that exist in the data (Calinski & arabasz, 1974). Lastly, we used six consecutive choropleth maps o reveal the spatio-temporal variations that exist within Ghana’s ural areas based on the percentage of candidates who passed the ECE from 2009 to 2014. To make the map easy to interpret with- ut excessive loss of detail, we used graded colors with a five- evel equal interval classification scheme—that is, 20%, 40%, 60%, 0%, and 100%—for each wave of data. This visualization scheme s based on the recommended four to six classes used in most aps (Yang, 2005). We also computed and mapped out the annual hanges in BECE pass rates across rural areas. . Results The mean academic performance profiles for rural and urban istricts and the national average are displayed in Fig. 1. Overall, he downward direction of the trend for both rural and urban dis- ricts is similar to the national trend. The fairly parallel profile for ural and urban districts suggests no interaction between district ype and time. In other words, rural districts did not catch up with he urban districts during the 6-year observation period nor did he urban ones fall to the level of the rural areas. Fig. 2 builds on Fig. 1 by illustrating the rural–urban gaps nd their statistical significance at the national level from 2009 o 2014. The extent of this gap remained statistically significant at he .01 and .001 significance levels over the six-year period. Al- hough the rural–urban gap narrowed marginally after 2009, the verage performance of urban districts in subsequent years re- ained significantly higher than rural districts. As Fig. 2 shows, he largest differences between the rural and urban districts oc- urred in 2009 (15.07%, t = 4.42, p < .001) followed by 2014 D.

This finding means that the stimated initial average BECE pass rate decreased after 2009. The uadratic effect was positive and statistically significant (b = 7.52, < .01) but the cubic effect was negative and statistically signifi- ant (b = −.85, p < .001). These results, which are consistent with he mean profiles in Fig. 1, show that the pass rate initially de- reased in 2010, increased in 2011, and then decreased again in 013 and 2014. However, the rate of deceleration gradually slowed own over time. The rural–urban status of the districts was a significant predic- or of the initial BECE pass rate (b = −23.15, p < .01) but not the inear (b = −10.37, p = .21), quadratic (b = −2.73, p = .29), or ubic (b = −23.15, p = .37) changes in the BECE pass rate. Thatig. 2. Illustration of statistically significant annual differences in BECE pass rate F etween rural and urban districts from 2009 to 2014. 2s, rural and urban districts had a statistically similar quadratic nd cubic rate of change in the BECE results. The rural–urban sta- us of districts explained 31% [(143.65–98.47)/143.65 = .3145] of he inter-district variations in the BECE pass rate. The negative orrelation between the intercept and the linear growth param- ter (b = −17.54, p < .01) means that districts with high BECE cores had a slower linear decrease, whereas districts with low ECE scores had a faster decrease in their linear growth over time. hus, the situation of the low scoring districts got worse over time. .2. Spatial grouping analysis results The parallel box plot in Fig. 3 illustrates the optimal dis- inct trajectories in the BECE results from 2009 to 2014. The alinski–Harabasz pseudo F-statistic for the grouping analysis re- ealed three geographically-diverse trajectories (pseudo F = 74.87). hese three trajectories are analogous to accelerating, decelerat-ig. 3.

The first statistically distinct trajectory, il- lustrated with a star–green line, reflects districts whose BECE re- sults are neither improving nor declining consistently. Although this group had relatively steady results over the years, their group mean hovered below the global mean throughout the 6-year ob- servation period. The second statistically distinct trajectory is il- lustrated with a triangular point red line. The line shows districts whose BECE pass rates have decreased consistently since 2009. Al- though still above the global mean, this group’s mean fell below the global upper quartile for the first time in 2014. The last statis- tically significant trajectory is illustrated with a circular point blue line that shows districts whose results increased steadily during the 6-year period. Throughout the study period, the BECE pass rate scores for this group (i.e., districts with steady increases over time) were greater than the global mean and global upper quartile. The parallel box plot also shows that the number of outliers increased over time; meaning that the number of districts with exceptionally good re- sults increased over the 6 years. Fig. 4 presents the localized results of the grouping analy- sis, and shows the three statistically significant unique trajectories identified using the ArcGIS Grouping Analysis tool. The green dis- tricts have relatively stable trajectories. One noticeable result from the map is that majority of districts in the northern regions are neither improving nor declining in their BECE performance. The red districts experienced steady decreases in BECE pass rates over the study period. A disproportionate number of districts with de- clining trajectories were located in the southern regions. The blue districts experienced steady improvement in the BECE pass rates over the 6-year study period, and were located in the southern re- gions, especially in southwest Ghana. The unshaded white areas indicate districts with growth trajectories that did not fit any sta- tistically distinguishable pattern for growth trajectories. Overall, Fig. 4 shows that most districts in northern and eastern Ghana are neither improving nor declining compared to those in southwest Ghana. The southern region is the most diverse because its districts have a noticeable variety of trajectories. Specifically, the Ashanti Region in the south is the most promising region in terms of the number of districts with an accelerating growth trajectory or improving performance. In contrast, the Western Region is the worst performing region given its high number of districts with a declining BECE performance trajectory. 5.3. Inter-rural spatial variability Fig. 5 shows the spatial distribution of Ghanaian rural districts by academic performance from 2009 to 2014. Each panel, particu- larly before 2014, illustrates the dynamic nature of the BECE pass rates, which suggests some rural areas outperform others. The spa- tial distribution shows a wide but shrinking inter-rural variation in the BECE pass rate over time. In other words, the differences that exist between rural districts have narrowed over time. However, the results show that the primary reason for the narrowing gap be- tween rural districts is due largely to the fact that many districts that used to perform well on the BECE have experienced gradual decline in their BECE results. That is, the darker shades have pro- gressively gotten lighter, which suggests worsening trends in rural areas. Fig. 6 shows the annual changes in rural area performance from 2009 to 2014. Panels a through e show that some rural districts ex- perienced yearly increases in their pass rates (blue shades) while others experienced declines (red shades). The five panels show clear patterns or clusters, thereby confirming variability within ru- ral areas. The maps also confirm results from Fig. 5 that the nar- rowing inter-rural gap is not because low-performing districts have improved, but rather well-performing districts have declined inheir performance on the BECE. .4. Inter-urban spatial variability Trends in the inter-rural comparison is similar to trends in he inter-urban comparison. As panels a through f in Fig. 7 show, he spatial distribution of academic performance in Ghanaian ur- an districts varies. The spatial distribution shows moderate inter- rban variations in the BECE pass rate during the study period. anels e and f in Fig. 7 show that the inter-urban differences have lso narrowed over time, but there is still a fair amount of inter- rban variation compared to the inter-rural variation. Fig. 8 shows the pattern of annual changes in the BECE pass ate in Ghana’s urban areas. Panels a through c show that the ur- an areas of Ghana experienced a mix of improvement and decline n their BECE results from 2009 through 2012. However, the extent f inter-urban variation shrunk from to 2012 to 2014 largely be- ause more urban districts experienced decline in their BECE result uring the last two years of the study period. This trend is similar o the trends observed among rural districts. .5. Rural–urban spatial variability There are rural–urban similarities and differences in BECE pass ates. Results from Fig. 9 show that both rural and urban districts ave representation of the three statistically distinct trajectories of ECE pass rate in Ghana: improving, declining, and stable trends. n addition, both rural (31%) and urban (32%) areas have equiva- ent proportions of districts whose trajectories are not statistically nclassified. On the other hand, there are many rural–urban dif- erences in Ghana’s BECE pass rate. First, most of the rural dis- ricts are located in the northern and middle sectors of the coun- ry, whereas nearly all the urban districts are located in the south f the country. Second, as evident in panels a and b of Fig. 9, ru- al districts are largely neither improving nor declining (58%) com- ared to urban districts (41%). Third, a higher proportion of urban istricts showed consistent signs of improvement (24%) during the tudy period compared to a handful of rural districts (5%). Another mportant rural–urban difference in performance at the BECE is hat the declining districts, though few, are somewhat spread out mong rural districts in the south, middle, northern Ghana, while hose of the urban districts are clustered in the south, particularly he southwestern part. . Discussion The goal of this study was to model changes in the percent- ge of candidates who passed the BECE over a 6-year period and o determine whether the pattern of change over time differed ased on the urban or rural status of Ghana’s administrative dis- ricts. At the national level, the BECE performance trends suggest hat the initial results followed a fluctuating pattern until the last 3 ears when they declined consistently. The recent trend at the na- ional level, lends credence to concerns expressed by Degue (2012), ewin and Akyeampong (2009), and others on the falling BECE per- ormance and academic standards in Ghana. Our results are also onsistent with Ghana’s poor performance at several international chooling rankings. For instance, in a 2015 global report on math nd science education published by the Organization for Economic o-operation and Development (OECD), Ghana placed last behind ther African countries such as Tunisia, Morocco, Botswana, and outh Africa (Darko, 2015). Ghana has also consistently lagged be- ind other peer African countries, including South Africa, Morocco, otswana, and Egypt in the 2003, 2007, and 2011 editions of the rends in International Math and Science Study (TMISS) (Abukari, 010; Etsey et al., 2009).

Results of grouping analysis showing spatial variability in the growth trajectories in BECE results from 2009 to 2014. m i s e i p c s i g T i f t s t r d p p G C m m w i l t i c n c t eThe clear implication of our findings and those of other studies s that the Ghanaian government and other education stakehold- rs should worry about the trajectory of the country’s academic erformance. The results of our spatial grouping analysis demon- trate that of the 120 districts statistically classified into distinct roups, a significant majority (66%) experienced neither consistent mproving nor declining BECE performance. Moreover, these dis- ricts consistently performed below the national average during he study period. In other words, this group, which dominates the istricts in most of the regions in Ghana (Upper East = 90%, Up- er West = 78%, Northern = 60%, Volta = 70%, Eastern = 56%, and entral = 79%), has not experienced meaningful, steady improve- ent in BECE performance since 2009. This finding confirms the idely held view that academic standards at the basic education evel in Ghana remain low (Gyan et al., 2014). Moreover, this find- ng is alarming because the districts in the stable group represent early two-thirds of districts in Ghana and have a large number of he country’s junior high school students. While internal migrationay be a predictive factor for the observed trends, emigration of tudents from low-performing districts may not possibly be a dom- nant reason why low-performing areas continue to do poorly be- ause internal migration between rural and urban areas in Ghana s not highly skewed in one direction (Anarfi, Kwankye, Ababio, & iemoko, 2003; Castaldo, Deshingkar, & McKay, 2012). In fact, data rom the fifth round of the Ghana Living Standards Survey (GLSS 5) how that majority of internal migrants move largely towards ru- al areas (Ghana Statistical Service, 2008). Certainly, this persistent oor performance at the BECE points to persistent weaknesses in hana’s efforts to improve its basic education system. In the face of such poor performance at the BECE, reassess- ent of the current education programs is warranted. The BECE tself may need to be evaluated on whether it is currently the op- imal assessment tool for academic performance at the JHS level. A ross-country assessment between Ghana and other West African ountries such as Gambia, Liberia, and Sierra Leone that use the quivalent of the BECE as an assessment tool would be useful to 8 D.

Education stakeholders and administrators of exam- inations in Anglophone countries of West Africa already recognize that external examination should not be the only measure of learn- ing outcomes at the JHS level; thus, they reformed the BECE nearly a decade after its inception to take into account teachers’ contin- uous assessment of students’ in-class performance (Akyeampong,997). The ratio of the external exam to the continuous assess- ent, which started from 60:40, is now 70:30, and there are rec- mmendations to change to a 50:50 ratio (Dery & Addy-Lamptey, 010). There is similar ongoing debate in several African coun- ries about the appropriate weighting system for the continuous ssessment and external examination (Kapambwe, 2010; Kellaghan Greaney, 2003; Pudaruth et al., 2013). It is important that the nsuing decisions to replace or augment the one-shot external ex- D. Ansong et al. / Applied Geography 65 (2015) 1–12 9 Fig. 9.

Besides the need to reassess the BECE weighting format, addi- ional government actions may be needed to address the problem f low performance at the BECE and the rural–urban differences. It s not as though government and stakeholders have completely ig- ored the problem in the past decade. In fact, government expen- iture on basic education has tripled in the past decade, yet learn- ng outcomes at the junior high school level have not improved Darvas & Balwanz, 2014). Perhaps, the government’s education in- estment choices have targeted the access-challenges to the detri- ent of academic quality concerns. Notably, the introduction of ajor educational initiatives in Ghana such as the Free Compul- ory Universal Basic Education (FCUBE) policy in 1996, the Capi- ation Grant Scheme in 2004, and the Ghana School Feeding Pro- ram in 2005, and free school uniforms in 2009 have had signifi- ant impact on universal access to basic education (CREATE, 2008). t is however, not clear the extent to which these programs have irectly affected the lagging performance standards. It is essential hat government, policy makers, and stakeholders focus adequate ttention on performance standards, similar to the efforts directed t investments in access basic education. Another key finding of this study is the varying space-time pat- erns of academic performance at the BECE in the 2009–2014 pe- iod. In contrast to the national trends, in-depth district-level anal- sis shows more nuanced variations in BECE results than the global rends suggest. Significant geographical variations exist in perfor- ance trends, which is likely due to spatial disparities in access o pedagogical resources and infrastructure (Ansong et al., 2015). or some districts, mostly in the central, eastern, Volta, northern, nd upper regions of Ghana, the proportion of candidates passing he BECE remained relatively stable over the 6-year study period. ther districts, most of which are in the Ashanti (southern) region,ave consistently experienced annual increases. The Ashanti region ouses Ghana’s second largest city and a network of urban centers Otiso & Owusu, 2008), hence the region is well-endowed with ducation resources, such as a high proportion of trained teach- rs, which is critical for learning outcomes (Ministry of Education, 013). In contrast, another group of districts mostly in the west- rn (i.e., Nzema East, Aowin-Suaman, and Bia) and Brong Ahafo re- ions (i.e., Tano South, Pru, and Jaman South) experienced steady ecline over the 6-year study period. The only glimmer of hope for he academic performance of these downward-trending districts is hat they have not yet fallen below the national average. This opti- istic assessment gives local authorities a window of opportunity o thoroughly explore localized, targeted interventions to reverse heir decline in BECE performance. We also found that some districts, the majority of which are n southern Ghana, did not fit any of the three distinct profiles. hese districts are not in the blue, red, or green zones of Figs. 4 nd 9, which means they have not consistently experienced de- lines, improvements, nor stability in their BECE performance. This nding does not mean that the statistically unclassified districts do ot have academic performance challenges. Rather, those districts ave unpredictable trajectories and this uncertainty can hamper ef- ective educational planning. The fact that those districts do not ave an upward trajectory (i.e., do not show consistent improve- ent) require attention because their BECE performance does not eem to be commensurate with increased education investment. oticeably, most of the statistically unclassified districts in south- rn Ghana (i.e., 76% in Fig. 4) are adjacent to blue-shaded districts i.e., districts with ideal growth trajectories). Because of data limi- ations, our study is not able to offer insights into the reasons for ontrast between contiguous districts. It will be important for fu- ure studies to investigate the reasons for the sharp contrasts in ECE performance between contiguous districts. In the normal scheme of things, variability in academic perfor- ance should not necessarily be a cause for concern. However, in hana’s case, stakeholders should be concerned given the conspic- 10 D.

Moreover, even more worrisome is the long-range forecast for Ghana’s academic perfor- mance. Specifically, the multilevel growth curve modeling used in this study revealed higher-order polynomial trends (i.e., quadratic and cubic slopes) that suggest the low-performing districts, partic- ularly the red-shaded districts, are unlikely to improve their per- formance at the BECE in the near future. In other words, with- out more effective targeted programs and interventions, the worse- performing school districts will continue to get worse, further widening the educational inequality gap, which has a huge impact on individual welfare. Government, policy makers, and stakehold- ers cannot afford to ignore this potential for further decline in per- formance at the BECE. The potential for further decline can be reversed if serious lo- calized measures are undertaken to improve performance stan- dards in the low-performing districts. Evidence from a growing body of empirical studies and program reports from Ghana and other African countries suggest that decentralized measures that devolves power to schools and school districts fosters commu- nity and parental involve which are associated with improved aca- demic outcomes (Dowd, 2001; Hyde, Kadzamira, Sichinga, Chib- wana, & Ridker, 1997; Odonkor, 2000). Results from our study sug- gest that poor academic performance at the BECE is most likely a local issue because multiple trajectories exist within each region or even within the rural clusters shown in Fig. 6. The localized nature of the academic performance problem is precisely the rea- son why southwestern Ghana not only has the highest number of districts with positive trends (blue-shaded districts) but also has a disproportionally large share of poor-performing districts (red- shaded districts). There are promising districts within rural clus- ters, as shown in Fig. 6, because some rural districts have experi- enced improvements in BECE pass rates from time-to-time. It will be important for future studies to examine and glean lessons from the unique characteristics and success stories of districts such as Kintampo South and Kassena Nankana West that are deprived ar- eas that have managed to experience a steady upward trajectory in the proportion of candidates passing the BECE. Another finding of this study is that the noticeable spatio- temporal patterns in academic performance at the BECE generally follow the lines of rural/urban divide, which is in line with findings from a similar study in Kenya (Kimosop et al., 2015) and Uganda (Kasirye, 2009). Results of our multilevel growth curve model- ing revealed that rural districts experienced disproportionate BECE performance declines whereas urban districts largely experienced increased fortunes. As shown in Fig. 2, whereas the rural–urban gap narrowed marginally after 2009, a substantial gap still remains partly due to the well documented rural–urban gap in socioe- conomic development and educational resources (e.g., textbooks, trained teachers, physical infrastructure, and school supervision) that is in favor of urban areas (see Otiso & Owusu, 2008; Poku- Boansi & Amoako, 2014). Worryingly, forecasts from our higher- order polynomial trends suggest that if nothing is done, the rural– urban BECE achievement gap will continue to widen in the future. Therefore, the critical question is whether stakeholders can inter- vene in ways that will enable rural areas to narrow the gap with urban districts. Although daunting, such improvement in rural aca- demic performance is possible given the right intervention. The practical way forward should perhaps begin with the ad- mission that a blanket global view of academic standards in Ghana masks the needs of certain areas that require additional localized interventions beyond the general efforts of government. This ob- servation has important implications for the approaches that pol- icy makers could use to address local challenges in BECE perfor- mance. Spatially targeted approaches to addressing the education challenges in Ghana are needed. Evidence suggests that interven- tions that target specific marginalized communities produce bet-er outcomes. One such intervention is the Education for Empow- rment program, which is a partnership between IBIS, a Danish on-governmental organization, and the Ghana Education Services GES). The program, which seeks to bridge the educational inequal- ty gap between rural and urban Ghana has yielded positive educa- ional outcomes (Darvas & Balwanz, 2014). Other spatially-oriented nterventions that have the potential to improve educational out- omes in deprived communities include the GES’s supplemental unding to basics schools in deprived districts; the government’s ash transfer program to support poor households’ health and ed- cational expenditure; and incentives such as salary increments for eachers in deprived districts (Darvas & Balwanz, 2014; Ministry of ducation, 2012). .1. Limitations and strengths Two data-related limitations of this study are worth mention- ng. First, data on newly created districts were not available, and herefore, the present study could not examine the academic per- ormance of these districts. Moreover, this study modeled only six aves of BECE academic performance data, starting from 2009. Ex- anding the data to include BECE pass rates prior to 2009 might ffer further insights into the long-term trends in academic per- ormance. However, earlier waves of data were not available at the ime the present study was conducted. Despite these limitations, his study has the potential to advance the existing body of work n academic performance in Ghana in two important ways. First, he ability to model six waves of BECE data is an important im- rovement over the prior use of cross-sectional data to inform dis- ussions about academic performance trends. Second, the analyt- cal approach of combining growth curve modeling with spatial tatistics is a superior approach that offers rich insights into the patial and temporal dimension of academic performance. . Conclusion Ghana has outpaced most developing countries in education in- estments and expenditure, and has made huge gains in access to ducation, but quality concerns remain. While the results of the resent study validate the concerns of some stakeholders that aca- emic standards are generally low, the trajectory of academic per- ormance shown herein is more nuanced, with some districts de- lining, improving, or reaming stable. An important lesson from his study is that there are diverse geographical trajectories, and herefore, a localized approach to addressing the academic per- ormance challenges at the junior high school level in Ghana is he prudent approach. As discussed earlier, the patterns of change n the percentage of candidates passing the BECE from 2009 to 014 differs not only between the rural and urban districts but lso within rural districts. This study cautions that barring any tar- eted intervention, rural–urban gap in performance at the BECE ould widen. Government, researchers, education stakeholder and he media should also discuss the problem from a spatial perspec- ive because some districts need additional attention and support o reverse their downward trend at the BECE. If social inequality n Ghana is to be addressed, then spatial disparities in the quality f education must be addressed in order to offer all young citi- ens better and equitable educational opportunities. Such a situa- ion would ultimately go a long way in enhancing the well-being nd quality of life of the citizenry as well as ensuring sustainable ivelihoods. eferences bukari, Z. (2010).
