This paper uses a RCT to estimate the effectiveness of guided instruction methods as implemented in under-performing schools in Chile. The intervention improved performance substantially for the first cohort of students, but not the second. The effect is mainly accounted for by children from relatively higher income backgrounds. Based on the CLASS instrument we document that quality of teacher-student interactions is positively correlated with the performance of low income students; however, the intervention did not affect these interactions. Guided instruction can improve outcomes, but it is a challenge to sustain the impacts and to reach the most deprived children.
