DP16471 Let's stay together: the effects of repeated student-teacher matches on academic achievement
We explore the effectiveness of repeating the student-teacher match on test scores, for the universe of 8th graders in Chile using information on all student-teacher matches across multiple subjects and years, and a national, anonymous measure of test scores. Also, we exploit a plausibly exogenous source of variation in the process of repeating matches generated by a discontinuity in teacher retention at the legal retirement age. Repeating matches has a robust positive effect on test scores which aggregates up to the student, class, and school-level. As channels, we report a positive effect on attendance, progression, student behaviour and teacher expectations.
