“School Quality and the Return to Schooling in Britain: New Evidence from a Large-Scale Compulsory Schooling Reform”, Damon Clark2023-07 ()⁠:

[see previously Clark & Cummins2020] What is the causal effect of schooling on subsequent labor market outcomes? In this paper I contribute evidence on this question by re-examining a British compulsory schooling reform that yields large-scale and quasi-experimental variation in schooling.

First, I note that this reform was introduced in 1947, when British students attended higher-track (for the “top” 20%) or lower-track (for the rest) secondary schools. The reform increased the minimum school leaving age 14 → 15 and I show that the vast majority (over 95%) of affected students attended lower-track schools.

Second, I show that the additional schooling induced by the reform had close to zero impact on a range of labor market outcomes. Third, I attribute these findings to the quality of these lower-track schools, which I argue was low along several dimensions.
