Using a stacked difference-in-differences design covering shootings between 1990 and 2025, I compare cohorts at affected universities before and after the shooting with cohorts at matched control universities. I find no detectable effects on time to degree, but undergraduates enrolled at the time of the shooting are 4.2% less likely to pursue further studies. Those who do continue shift toward health: the share of exposed cohorts who later enroll in a health degree rises by 1.3 percentage points (8.8%), and this effect persists among cohorts who enroll after the shooting. Effects on students present during the shooting are consistent with a response to trauma; for later cohorts, I find evidence of sorting, as master’s students with prior healthcare experience become more likely to enroll in affected universities.…
