Tuition Scholarships, DSS Daycare Subsidy, and Military Fee Assistance

Castle Island’s mission is to provide world-class and financially accessible education.


Tuition for your child will be between $4,500 to $11,000 per school year based on family income*. A non-refundable $250 deposit, included in tuition, is required to secure your child's enrollment.


Families who qualify for Daycare Subsidy or Military Fee Assistance, can select Castle Island as their childcare site; the subsidy will pay for a percentage of the tuition.


Once the registration process has been completed, your family’s tuition and payment options will be offered in your child's enrollment contract.


*If your family's annual household income is under $100,000 and you are interested in qualifying for a Tuition Scholarship, please send documents to the school office showing annual household income used to support your child, ie. income tax returns, pay stubs, order of support, etc. 


Contact Diane Nickerson, School Director, for more information.

Education is education. We should learn everything and then choose which path to follow. Education is neither Eastern nor Western, it is human.
