Note. Reference group is the promotion group. The marginal effects are shown in percentage change for dichotomous outcomes. Results are adjusted for covariates: sociodemographic factors, CPC program participation, and early scholastic abilities, as listed in the measures section. Participants retained in both early and late were excluded from the analyses: 24 for college measures and 22 for public assistance measures. Sample sizes for early, late retention, and promotion groups are 215, 91, and 845 for 2-year college attendance, and 195, 86, and 754 for 4-year college attendance.
