Abstract
|
Before
This study evaluates a restorative practices (RP) intervention designed to reduce peer violence in schools in Bogota. A total of 300 classrooms—150 treatment and 150 control— grades 7-9 currently experiencing conflictive situations will participate. The intervention comprises structured sessions facilitated by trained professionals focusing on strengthening socio-emotional skills for assertive conflict management (self-awareness, empathy, decision-making), rooted on restorative practices principles. Random assignment occurs at the school-classroom level, and outcomes are measured using administrative data and follow-up surveys (N=30 students per classroom, on average). The study will test the impact of the intervention on peer violence, students’ psychosocial well-being, class social cohesion and learning.

This study evaluates a restorative practices (RP) intervention designed to reduce peer violence in schools in Bogota. A total of 240 classrooms—120 treatment and 120 control— grades 7-9 currently experiencing conflictive situations will participate. The intervention comprises structured sessions facilitated by trained professionals focusing on strengthening socio-emotional skills for assertive conflict management (self-awareness, empathy, decision-making), rooted on restorative practices principles. Random assignment occurs at the school-classroom level, and outcomes are measured using administrative data and follow-up surveys (N=30 students per classroom, on average). The study will test the impact of the intervention on peer violence, students’ psychosocial well-being, class social cohesion and learning.

Power calculation: Minimum Detectable Effect Size for Main Outcomes
|
Before
MDEs based on 2023 data suggest 0.07–0.1 SD detectable effects on primary outcomes with 150 treated and 150 control classrooms, ~30 students per class, given significance level of 0.05 and statistical power of 0.80.
To increase statistical power, the experiment will include a pure control arm that won’t be invited to the intervention nor surveyed. I will test impacts using administrative data (which includes violence and educational attainments).
