The GreenMount School has a limited financial aid fund. First priority is given to the GMS families already receiving financial aid. Next priority is given to GMS families who are not currently receiving financial aid, and finally, to new families.

Tuition assistance is awarded on the basis of need alone. Applications to the Tuition Aid Data Service (TADS) are available upon request and must be submitted with the school application. There is a separate minimal processing fee for using this service.
