This study’s mixed-methods research design, combining quantitative and qualitative approaches, provides a comprehensive analysis of the impact of the instructional materials-to-students ratio (IMSR) on academic performance. Utilizing stratified random sampling, the research encompasses 22 schools, 132 teachers, and 220 students across various wards. Descriptive statistics indicate an adequate average of 150 instructional materials per school, with textbooks being the most common type. The median number of students per school stands at 350, reflecting a typical school size. T-tests reveal significant differences in biology scores due to IMSR ((t (350) = 2.45, p < 0.05)) and notable improvements in physics scores with new materials ((t (350) = 5.67, p < 0.01)). Chi-square tests show a significant correlation between teacher access to materials and student achievement ((χ² (2, N = 132) = 9.81, p < 0.01)). ANOVA and MANOVA analyses confirm the substantial impact of IMSR on achievement scores and the combined effect of IMSR and school level on academic scores. Regression analysis identifies IMSR as a significant predictor of biology scores ((R2 = 0.25, F (1, 218), p < 0.001)). Correlation analysis suggests a moderate positive relationship between the availability of instructional materials and student achievement ((R = 0.45, p < 0.001)), while factor analysis reveals strong associations between material types and achievement. Non-parametric tests, such as the Mann-Whitney U and Kruskal-Wallis H, highlight significant differences in biology and chemistry scores based on IMSR levels and material types, respectively. The study robustly demonstrates the influence of instructional materials on educational outcomes.
