The Denver Preschool Program (DPP) makes high quality preschool possible for every Denver 4-year-old regardless of their family income or neighborhood through tuition support to families and quality investments in preschool programs. The DPP conducts annual evaluations of DPP students beginning in the fall of their preschool year and continuing on through their early elementary years to ensure the program is fulfilling its promise to prepare students for kindergarten and measure the progress of those students over time to determine how those results persist. This report focuses primarily on how well DPP students are doing in reading, writing and math on Colorado's third-grade Transitional Colorado Assessment Program (TCAP) and touches on what we know about how ready they are to learn in kindergarten.
