Sonshine Enrichment Center Preschool is part of Trinity Lutheran Church, and offers a Christian-based developmental program for children 2 to 4 years old. State-licensed staff work with the Pleasanton Unified School District to develop kindergarten-readiness curriculum. The school provides two, three and four-day per week classes depending on age. The "Exploring Preschool Together" (EPT) program is held from 10:30 a.m. to 11:30 a.m. on Friday mornings for 2-year-olds and a family member, and helps children become familiar and comfortable with preschool activities and environments. The parent-cooperative option offers parents the opportunity to work in the classroom about once every two weeks.
