In a series of randomized experiments, students participated in remedial tutorials conducted during school hours in small groups. Trained teachers used structured pedagogical materials that can be easily scaled up. Informed by the outcomes of each cohort, we fine-tuned the intervention tools for each subsequent cohort. We found positive and persistent impacts on literacy scores and positive spillovers on some mathematics scores. The effectiveness of the program grew over time, likely because of higher dosage and the fine-tuning of materials. UR - https://doi.org/10.18235/0002075 ER -
