Financial pressures on public doctoral universities are forcing them to seek more new student enrollments to grow net tuition revenues. This study evaluated public doctoral university net tuition revenue and its relationship with tuition discount rates and state appropriations. It focused on public doctoral universities with institutional enrollment and financial characteristics that would allow utilizing tuition discounting strategies to respond to changes in state appropriations. Using publicly available national panel data, this longitudinal quantitative project examined how public doctoral universities utilized tuition discounts and handled state appropriations to determine their relationship to net tuition revenue. It evaluated the relationship between net tuition revenue and tuition discount rates and state appropriations, producing four findings. First, it supports the literature about public doctoral university revenues shifting from public funding to tuition-support budget models. Second, tuition discounting practices may not be effective for growing net tuition revenue at public doctoral universities. Third, other factors, such as undergraduate residential tuition rates, total enrollment, state population, and state gross domestic product, could critically impact net tuition revenue growth. Finally, the growth in net tuition revenue may cause public doctoral universities to overemphasize the need for this type of funding. The findings indicate that public doctoral universities should resist matching their perceived competitors in maintaining or increasing tuition discount rates. Institutions must continue to enhance their relationships with state entities and oversight boards for their financial well-being. Besides seeking additional revenues, public doctoral universities should focus on financial efficiencies by shifting to expense-based budgeting practices.
