Our Programs

Play is the best way for children to explore and test possibilities; it's a doorway to problem-solving and the basis for discovery. Play equals learning. Harker Preschool combines child-centered learning and teacher-guided explorations in a community rich with music, art, movement and nature. Here, our littlest learners stretch their thinking, deepen their focus, and develop the social, emotional, physical and academic skills needed to thrive in kindergarten ... and life.

Ages 3 & 4

Our 3- and 4-year-old students meet in cottages that are large and filled with light, providing ample space for exploration and learning. Areas for whole-group and individual activities, teacher-directed small group sessions, skill-based learning centers and separate nap areas are all part of each cottage.


Transitional K

Our transitional kindergartners enjoy two large classrooms, each designed to bridge the gap between preschool and kindergarten for our young 5-year-olds, by providing plenty of space for familiar preschool materials and centers while introducing more traditional kindergarten seating and learning environments.
