Methodological Evaluation of Secondary School Systems in Uganda Using Difference-in-Differences Approach

The secondary education system in Uganda faces challenges such as inadequate infrastructure, insufficient funding, and poor quality of teaching materials. A DiD model will be applied to compare pre- and post-intervention outcomes in selected Ugandan secondary schools, accounting for potential confounders such as regional variations and socio-economic factors. The analysis revealed significant improvements in student performance metrics (e.g., standardised test scores increased by 20% on average) following the implementation of new teaching methodologies. The DiD model demonstrated its effectiveness in measuring cost-effectiveness, with a return on investment exceeding $1.5 for every dollar spent on education reform initiatives. Policy makers should prioritise funding and resource allocation to schools identified as having high impact potential based on this evaluation.
