Notes: Robust standard errors, clustered at the relative reading score level, are given in parentheses. Discontinuity estimates are obtained parametrically using the specified polynomial order and the score range. All regressions control for the student covariates listed above, cohort fixed effects, and within-school peer averages. Sample sizes are given in square brackets.

*Statistical significance at 10%; **statistical significance at 5%; ***statistical significance at 1%.
