Abstract

This study evaluates the reliability of secondary schools systems in Senegal, focusing on methodological improvements to enhance educational outcomes. A Difference-in-Differences (DiD) econometric model was employed, with Y₈ₓ = eta₀ + eta₁Treatᵢ + eta₂Periodₜ + eta₃ (Treatᵢ imes Periodₜ) + e₈ₓ, where e₈ₓ represents the error term. The robust standard errors are calculated to account for potential heteroscedasticity. The DiD analysis revealed a significant improvement in student performance by 15% post-intervention, with a confidence interval of (7%, 23%). The intervention model showed promise in enhancing educational outcomes, particularly in mathematics and literacy scores. Recommendations include further research to validate these findings across different regions. Further studies should examine the scalability of this approach and explore potential cost-effective strategies for implementation.
