Universal Preschool Program (UPK)

Each school year, all 4-year-olds will qualify for 15 hours of free preschool a week in the year before they start kindergarten. Youth must turn 4 years old by October 1, 2025 for the 2025/26 school year.  We will offer the following kinder readiness options for 4-year-olds who qualify for UPK funding. Families must complete the initial registration process through the state portal to match with the City of Thornton Preschool Program.  We will work with families to complete our internal registration process once they are matched with our program.  Contact the preschool director, Sharon Juel at Sharon.juel@thorntonco.gov for kinder readiness private pay options.
