​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
