We estimate the causal effect of attending a state Faith school on primary education achievement in England using administrative student-level data and implementing various strategies to control for students’ selection into Faith schooling. Our regressions control for fixed effects in prior achievement and residential postcode to compare pupils who are close residential neighbors and have identical observable ability. We also use information on future school choices to control for preferences for Faith schooling. Results show that pupils progress faster in Faith primary schools, but all of this advantage is explained by sorting into Faith schools according to preexisting characteristics and preferences.

We study ability peer effects in English secondary schools using data on four cohorts of students taking age-14 national tests and measuring peers’ ability by prior achievements at age 11. Our identification is based on within-pupil regressions exploiting variation in achievements across three compulsory subjects tested at age 14 and age 11. Using this novel strategy, we find significant and sizable negative effects arising from bad peers at the bottom of the ability distribution but little evidence that average peer quality and good peers matter. However, these results are heterogeneous, with girls benefiting from academically bright peers and boys not.
