The Denver Preschool Program
Key Findings from a Decade and a Half of Implementation
Research has consistently shown the importance of high-quality preschool for children’s school readiness skills and early elementary academic success 1. Closing the preschool opportunity gap by helping families access high-quality preschool has also been found to be one of the most impactful strategies for narrowing the academic achievement gap 2. As a result, high-quality preschool is seen by policy-makers, educators, families, and researchers alike as a sound economic investment, with an approximate $4.00 societal savings for every dollar on preschool spent 3. Yet many families in Denver have not historically had access to high-quality preschool, creating substantial opportunity gaps and widening differences in early academic outcomes between children residing in lowerincome households and their more economically advantaged peers 4
To address preschool opportunity gaps and advance racial and economic equity in opportunity and outcomes, Denver voters passed a sales tax in 2006 to help all Denver families access high-quality preschool. The sales tax established the Denver Preschool Program (DPP) which now provides a tuition credit for all families of 4-year olds in Denver to attend a preschool of their choice. The tuition credit is scaled to family income, family size, and to the quality of a preschool a family selects for their child. The DPP also provides resources to preschools to improve the quality of their programming in ways that support children’s school-readiness skills.
Over the past 15 years, the DPP has fundamentally changed the landscape of preschool opportunity in Denver, has enhanced the school readiness and longer-term early elementary academic outcomes of children who have participated, and has helped to support teachers and stabilize preschool programs in the face of the Covid-19 global pandemic. This research brief highlights key evaluation findings from the DPP over the last 15 years.
Key Findings

DPP tuition credits have reduced families’ out-of-pocket preschool expenses and enabled many families to be able to work and for longer hours, which together have reduced many families’ economic stress, especially for families with lower household incomes.

DPP children were also less likely to be chronically absent and repeat a grade in the early elementary grades than children who did not participate in the DPP.
