Achieving equitable, quality education for all is a global development agenda as SDG4 stipulates. However, the existing research body insufficiently informs if there is an equity effect of educational intervention. The present study explores the equity effect of a project-sized intervention in education by examining an in-service teacher training project in Senegal. The study examined the data on math comprehension of 368 teachers and 2100 students from 91 schools in 8 provinces across Senegal collected through multistage random sampling.
The Project observed an equity effect; math comprehension improved while disparity diminished before and after the intervention for both teachers and students. For a school to gain mean score, reduction in learning gap within a school is indispensable; when a school fails to reduce the learning gap within, it also fails to gain the mean score. Further, there was a dynamism involving efficiency and equity. While mean score continuously improves, diminish in SD (standard deficiency) is most evident upon arrival of the intervention at target school, then SD reduction is limited during the next 3-5 years, to recover by the seventh year finally. The observed dynamism coincides with a shift in the beneficiary group: upon intervention arrival at school, it benefited students with a lower score, before benefitting students with a higher score as intervention period get longer. Such a dynamism suggests an interaction between teacher capacity development and student’s achievement.
Equity and efficiency are not necessarily trade-offs but can co-exist with project-sized intervention; however, a considerable portion of the target (approx. 10%) are left behind in the Project. Those left behind schools may exist in any project setting, and they need supplemental support. The study suggests that attention to the learning gap within a target group and continuous (not one shot) intervention is indispensable to materialize the equity effect of a project-sized educational intervention.
