The Denver Preschool Program makes quality preschool possible for all Denver families with 4-year-old children through a dedicated sales tax first approved by voters in 2006 and renewed and extended in 2014. Through the 2017-2018 program year, DPP has provided more than $106 million in tuition support to help more than 50,000 Denver children attend the preschool of their family’s choice, establishing each child’s foundation for lifelong learning and success.
