Methods Using a longitudinal comparative design, enrollment and graduation records were analyzed for six cohorts (2019–2024) across a 2-year community college district and two 4-year public universities. Three groups were compared: CBSP participants, TFW-only recipients, and general students. Year-to-year retention and on-time graduation rates were computed per cohort, with graduates excluded from retention denominators. Logistic regression assessed group differences in next-year retention and on-time graduation, controlling for enrollment intensity (full-time vs. part-time) and entry type (FTIC vs. transfer).
Results CBSP participants consistently outperformed TFW-only peers on retention across institutions and cohorts, and also exceeded retention rates among general students. In the 2019 cohort, one-year retention for CBSP students was 90.9% at 4-year-A, 80.0% at the 2-year institution, and 82.9% at 4-year-B, well above the 42.9%, 55.9%, and 44.1% observed for TFW-only students, and the 67.9%, 55.4%, and 68.2% for general students. Models confirmed significantly higher adjusted odds of retention for CBSP students relative to both TFW-only and general peers (e.g., OR = 4.54 [1.04, 19.77] vs. general at 4-year-A; OR = 2.62 [1.54, 4.44] vs. general at the 2-year institution in 2019). Full-time enrollment (e.g., OR = 1.84 [1.72, 1.97] at 4-year-B in 2019) and FTIC entry at 4-year-A and the 2-year institution (e.g., OR = 1.49 [1.29, 1.71]) were independently associated with stronger retention.
Graduation findings were more nuanced. At 4-year institutions, CBSP students showed higher adjusted odds of on-time completion than TFW-only peers (CBSP OR = 0.48 [0.27, 0.85]; TFW OR = 0.27 [0.08, 0.96], both relative to general; p < .05), though both groups trailed general students. At the 2-year institution, CBSP enrollment was not significantly associated with graduation (OR = 0.50 [0.20, 1.26]). Full-time enrollment strongly predicted completion in both sectors (OR = 17.0 [11.9, 24.1] at the 2-year institution), and a significant FTIC × Full-time interaction at 4-year institutions (B = 2.82, p < .01) showed the full-time advantage was amplified for FTIC students.
Conclusions and Implications CBSP participation is associated with stronger retention among foster care alumni and higher on-time graduation odds than tuition support alone, even where CBSP students do not yet match general-student completion. Findings support a "support plus tuition" model over tuition assistance alone. The independent effects of enrollment intensity and entry type underscore the need to address full-time enrollment and academic preparation within comprehensive support models, advancing rigorous inquiry for the common good.
