ISB enrolls students from a variety of socioeconomic backgrounds as part of our commitment to building a diverse and inclusive school community. Our need-based financial aid program is available to students at all grade levels to help families bridge the gap between what they can financially contribute towards their child’s tuition and the full annual tuition fee.
For the 2025–2026 academic year, ISB awarded over $3.4 million in aid to 33% of the student body. Financial assistance extends beyond tuition, including assistance for After School Care and Athletics, the summer program, and Little Green Gourmets lunch program.
Our financial aid program is designed to meet a wide range of family circumstances, and the amount of aid given to families ranges from 5% to 95% of tuition.
If you plan to apply for need-based tuition assistance, please indicate that on your child’s admissions application.
Tuition assistance awards are determined through a comprehensive assessment of family finances, including income, assets, and household size. ISB uses a third-party platform, Clarity, to process tuition assistance applications. Clarity guides parent(s)/guardian(s) in completing a family application, which asks for information about income, expenses, assets, and liabilities. To start your application, click the button below.

In addition to a completed application, we request copies of last year’s tax returns (1099, 1040, 1040A, or 1040EZ) and W2 statements or other proof of income (if applicable) through Clarity. Self-employed parents should also include all related business forms with your 1040 file (i.e., Schedule C, Schedule E, 1120, 1065, and/or K-1).

Tuition assistance applications for the 2027-2028 school year will become available on October 1, 2026. The deadline to submit is December 3, 2026 for currently enrolled families and January 8, 2027 for applicant families. Applicant families should indicate on their admissions application that they intend to apply for tuition assistance.
Yes, families need to reapply every year. Tuition assistance awards are granted for one academic year at a time. Once assistance has been awarded, families can expect that it will be renewed, provided their financial situation has not changed substantially and that they have completed the Clarity application, including all required and requested documents, for the upcoming school year.
ISB’s tuition assistance committee reviews all applications in December and January and makes tuition assistance awards annually. The committee uses Clarity to process and analyze all applications. Clarity evaluates a family’s estimated contribution to tuition using factors entered in their application, such as income, cost of living, family size, real estate equity, liquid assets, business income, payments to retirement plans, discretionary spending, medical expenses, child support, rental or mortgage payments, etc. ISB’s Tuition Assistance Committee uses that estimate, in combination with completed tax documentation, to determine financial aid awards.The committee keeps all financial information confidential and makes awards regardless of race, color, sex, religion, creed, gender expression, national origin, ethnic group, or disability.
Yes, an appeals process is available for tuition assistance awards. Families are asked to complete an appeals form and provide additional information to help the tuition assistance committee better understand the family’s financial situation.
Tuition payments at ISB cover all school materials, books, field trips, and overnight trips. In addition to tuition, there is an annual Parents’ Association fee of $100 (one per family) and an annual laptop fee of $150 for students in 6th to 8th Grades.
Families receiving tuition assistance will receive the same percentage of assistance for additional fee-charging programs such as school lunch, After School Care, athletics, and the summer program.
Families must submit an application through Clarity to determine eligibility for tuition assistance. Families with a range of incomes may qualify for tuition assistance. Currently, 87% of families who receive tuition assistance have a combined annual household gross income below $350,000. Income is just one out of many considered factors; Clarity will gather income, assets, and liability data to determine your family’s expected financial need.
When a student enrolls at ISB without having applied for financial assistance, it is the school’s expectation that the family will not apply for tuition assistance within the first two years of enrollment. Exceptions may be made if there is demonstration of a significant change in a family’s financial circumstances. Families must notify ISB of any change of financial circumstances that may positively or negatively affect their ability to pay tuition.
Current families receive their tuition assistance awards along with re-enrollment contracts in January. Applicants who are offered admission to ISB and a tuition assistance package are notified of both when decisions are released in February. If you are applying off-cycle, we recommend that you check with the Admissions Office before applying for tuition assistance, as funds are limited beyond the priority admissions season.
Yes, international families can apply for tuition assistance. Families who do not have US tax returns are asked to submit alternate documentation regarding family finances and proof of income. The tuition assistance committee may request additional information or documentation if needed.
If your child is a French citizen, you may apply for a need-based Bourse from the French government. Please note that, in line with ISB’s accreditation from the French Ministry of Education, Bourse awards can be used for enrollment in Pre-K 3 to 5th Grade only. The Bourse is managed through the French Consulate and takes into account a family’s financial profile and assets to determine whether they qualify for government aid; it is not a subsidy program for families wishing to attend accredited French schools. Applicant families who plan to apply for the Bourse program should notify ISB’s Admissions Office and should also complete the Clarity tuition assistance application.
Families applying for the Bourse should contact the French Consulate. More information about the program and required documents can be found here: https://newyork.consulfrance.org/-bourses-aefe-.
We are now accepting applications for the 2027-2028 school year!
