The Grossmont College Child Development Center in Santee holds NAEYC accreditation as a lab school on Grossmont College Drive, enrolling children from five months through five years of age. Five age-segmented classrooms operate under dual California Department of Social Services oversight for separate infant-toddler and preschool buildings, and the center's early-literacy programming feeds into the children's reading initiatives at Santee Public Library on Carlton Hills Boulevard. The California Department of Education designated the facility a model training site for its Program for Infant Toddler Caregivers, and college students in the Child Development program complete required observation and practicum hours across all five classrooms. The preschool building opened in January 1989 and began operating a state-funded afternoon program for four-year-olds in 1993, serving 24 children at no cost to qualifying families. The infant-toddler wing's gross motor curriculum builds the balance and coordination foundation that structured physical-development training at Champion Gymnastics & Cheer on Prospect Avenue advances in school-age children. Total capacity spans separate infant-toddler and preschool allocations across two interconnected buildings, each operating under its own California DSS facility number.
