Discovery Days Preschool

Let the little children come to me, and do not hinder them, for the kingdom of God belongs to such as these. And Jesus took the children in his arms, put his hands on them and blessed them. Matthew 19:13-15

  • An outreach ministry serving young children ages one through five years old 
  • Open September through May
  • Meets Monday through Thursday at Derry Church, Hershey, PA

At Derry Discovery Days preschool, we consider it a privilege to care for your children, surrounding them with God's love as they discover the world around them, make new friends, create and play. Our goal is to provide a value-based program that helps children gain positive social, emotional, intellectual and physical experiences.

Please note the change in calendar for the 2020-21 school year. Due to lateness of Labor Day 2020, DDD will begin before Labor Day this school year to be more in line with the adjusted public school calendar year. We will continue to operate on a 38-week schedule, ending on May 20, 2021.
