  • Notes: This table shows IV estimates using the baseline specification in Table 3 for the first and second maximum-class-size thresholds separately (Panel A) and for the subsample of single school municipalities (Panel B). The results in Panel A use all available data around each discontinuity to estimate the class-size effect at each threshold, not only the observations with enrollment within ±15. The results in Panel B are based on 32 municipalities with only one school and use a sample of 4,134 individuals. Standard errors clustered at the school level are reported in parentheses.
