Cost & Discounts

Mosaic has a tiered payment system in an effort to better serve the entire PS 20 community. In this system families must assess their own tuition tiers.  

Please NOTE: tiered pricing and the scholarship application here are for afterschool only. If you need a scholarship for a Mosaic camp day, please email

Families must assess themselves honestly. The program cannot run without adequate financial support from the PS20 community. The money raised by Mosaic pays for Mosaic staff salaries and supplies. It also enables PS 20 to employ school aids and to provide additional programming for the whole school.

We know this payment system may be confusing. Please reach out to the director or parent volunteers at for help.

Mosaic offers a 7% discount for families who register for 5 or more days (across a family, not per-child) in a semester.  This discount will NOT be automatically applied but will come later as a refund after the fact.
