Parent Survey

Families are our most valued partners. You help to ensure that your children work hard to build the best possible future for themselves, their families and their community.

Every year, we ask our families to complete a survey to help us prepare for the next year. This survey helps inform what we are doing well and need to keep, what we need to improve and what programs we might need to add.

We appreciate if you took a moment to complete this survey at the following link:

If you have any questions, please call our main office at 215-400-7220.

Thank you for helping to make sure your children are getting the best education they can.
