The annual National Association of College and University Business Officers (NACUBO) Tuition Discounting Study (TDS) measures tuition discount rates and other indicators of institutional grant awards to undergraduates attending private nonprofit (independent) colleges and universities. The "2015 Tuition Discounting Study" report, based on survey responses from 401 private nonprofit NACUBO-member institutions, reports final institutional discount rates for academic year 2014-15 and preliminary estimates for academic year 2015-16. Other indicators included in the report are: percentage of undergraduates receiving institutional grants; average institutional grant awards as a percentage of tuition and fee prices, changes in net tuition revenue; total undergraduate institutional grant aid funded by endowment earnings; and percentage of institutional grants that meet students' demonstrated financial need.
