Notes: The table compares the IV baseline estimates (Panel A) to IV estimates obtained without controlling for demographics (Panel B). Standard errors are in brackets. *p < 0.10, **p < 0.05, ***p < 0.01 All regressions include dummies for after the Promise’s introduction, individual (pseudo-)eligibility, and graduation year.
