Evidence¶

Nguyen 2018¶

Nguyen, T.D., Kramer, J.W., & Evans, B.J. (2018). The Effects of Grant Aid on Student Persistence and Degree Attainment: A Systematic Review and Meta-Analysis of the Causal Evidence (CEPA Working Paper No. 18-04). Stanford Center for Education Policy Analysis. http://cepa.stanford.edu/wp18-04

q3 · i? · quant-synthesis · r3

OLS regression of each study's treatment effect on the average aid amount per study (Table 5); the authors call the estimates rough due to limited studies and assume a linear aid-impact relationship. The year-to-year persistence coefficient is statistically significant at 1.2 percentage points.

"For the year-to-year persistence estimate, we find that $1,000 of aid increases year-to-year persistence by a statistically significant 1.2 percentage points."

q3 · i? · quant-synthesis · r3

Same OLS dose analysis across studies for degree completion outcomes; the printed result is a statistically insignificant 0.8 percentage-point increase in on-time and delayed completion per $1,000 of aid. The authors flag limited degrees of freedom and possible non-linearity.

"For degree completion, we find $1,000 of aid increases on-time and delayed degree completion by a statistically insignificant 0.8 percentage points."

Discussion¶

Related Claims¶

• Grant aid programs bundling additional academic or social supports show larger persistence and completion effects than aid alone — related
• Effects of grant aid on persistence and completion are heterogeneous across studies, justifying random-effects meta-analysis — related
• Grant aid increases degree completion, raising on-time completion by 2.4 and delayed completion by 2.5 percentage points in U.S. causal studies — related
• Need-based grant aid improves persistence and completion while merit-only aid shows no detectable effect on these outcomes — related
• Grant aid increases postsecondary persistence, raising within-year persistence by 3.2 and year-to-year persistence by 1.8 percentage points in U.S. causal studies — a broader claim this one bears on
