We investigate the beginning of the school discipline pipeline using a reform in Charlotte-Mecklenburg Schools that limited the use of out-of-school suspension for students in grades K-2. We find that the reform reduced the likelihood of out-of-school suspension by 1.4 percentage points (56%) and had precise null effects on test scores and disciplinary infractions. This leads us to reject a key argument in favor of early-grade suspensions: namely, that early-grade suspensions improve classroom-level outcomes. For high-risk students, we find short-run increases in test scores that persist into third grade. The reform reduced the Black-white out-of-school suspension gap by 79%.
