This report is one of the first to examine federal student loan repayments for graduate institutions. While the data are not without limitations and this report is based only on two lists of 20 institutions each, the data reveal some important findings. Historically Black Colleges and Universities (HBCUs) have some of the weakest rates of loan repayment. They dominate the list of 20 institutions with highest negative amortization rates, and their repayment rates overall are lower than those in the for-profit sector. For-profit institutions number among the schools with moderately weak repayment rates and large aggregate outstanding balances. Many private nonprofit institutions also appear in the two rankings. These findings suggest that institution type does not guarantee that graduate students pay down their student loans in a timely manner, which is itself a proxy for quality and value. The differences illustrated in this report between the student-based negative amortization rate and the dollar-based measures of loan repayment show that using repayment progress as a quality-assurance metric is not straightforward. Per-student measures of repayment can differ markedly from those that gauge the total dollars repaid over a period of time in a cohort. Policymakers should assess which is better for the particular goal they are trying to achieve.
