  1. Notes: In addition to the variables shown, each regression also includes control variables for grade size and for the teacher characteristics listed in Table 1. Standard errors clustered at the school + grade + year level are in parentheses. *, **, and *** denote statistical significance of a two-sided test at the ten, five, and one-percent levels, respectively.
