Lower School Program

Questions? Email us at extension@oes.edu 

Extension offers after-school programming that is a true extension of the school day. Providing students with experiential learning experiences that give students in grades PreK–5 the chance to explore and grow in a safe and fun environment.

Through our after-school programs, we enhance the OES Mission and Vision.  We view the program through three lenses:

  • Students as Inquirers: cultivating curiosity, posing questions, designing solutions to create new understandings. 
  • Community and Belonging: nurturing a vibrant environment that meets the social, emotional, and developmental needs of all students.  
  • Collaboration across OES divisions and departments to engage and define a broader sense of community.

  • Program runs from August 31 - December 18, 2026
  • Monday-Friday, 3:00-5:30pm, 2:00-5:30pm on Wednesdays (early release)
