  • Notes: This table shows IV estimates using the baseline specification in Table 3, but where the sample is further restricted to graduating cohorts from schools where all nine years of compulsory school enrollment are observed. Standard errors clustered at the school level are reported in parentheses. *p < 0.10, **p < 0.05.
