​Licensed Preschool Program

The city of Thornton Preschool classes are designed to build upon one another. However, children can enter the program at any of the age-levels (they are not required to complete Beginner Preschool), as each age-level is developmentally appropriate for the designated age group. The curriculum is aligned with the Colorado Early Learning and Development Guidelines (ELDG).

These guidelines include indicators for the children to practice in physical development and health; social and emotional development; English language development; literacy; logic and reasoning; mathematics; science; social studies; creative arts expression; and approaches to learning.

Further information on the ELDG can be found at http://earlylearningco.org/.

The city of Thornton Preschool Program is a continuous program. Limited openings are available for the remainder of the school year. Please call 720-977-5901 to enquire. The city of Thornton Preschool Program is a state licensed program. Completed registration packets, including up-to-date physicals and immunization records from the child's physician, are required before your child can start classes. ALL CHILDREN MUST MEET AGE REQUIREMENT AND BE POTTY-TRAINED BEFORE THE FIRST DAY OF THE SESSION.
