tuition, Fees, & Financial aid

Understanding that an International School of Indiana education is a significant investment in a student's future, ISI is committed to supporting families from a wide range of financial circumstances. ISI tuition will remain frozen at current rates through the 2023-2024 academic year, eliminating uncertainty and providing peace of mind for families as they plan and prepare for the next school year.

Understanding Tuition and Fees 

The cost of educating an ISI student exceeds our tuition amount by several thousand dollars. We supplement the difference for all families by relying on philanthropic support, including individual and corporate donors. The High School also participates in the Indiana Choice Scholarship Program, known widely as the "Voucher" program.

ISI makes every effort to be as transparent as possible about the costs associated with an ISI education. Tuition & Fee Schedules are posted no later than January for the next school year, and families can also access a breakdown of institutional costs, including fee based programs like child care, enrichment, athletics and exchange trips.

Financial Aid

We encourage the families of all applicants to carefully review our tuition and fees and to evaluate their own ability to pay school costs for the coming year and in future years. If parents/guardians think they will need assistance with ISI tuition, they must apply at the time of admission. If the request for assistance is not made with a student's initial application for admission, consideration for financial aid will only be granted at a later date, including subsequent years, if the need is due to a significant, unexpected change in circumstances, for example, a job loss. 

Eligibility for financial aid is based on a family's demonstrated need -- as determined by important factors such as family income, assets, family size, and tuition obligations for other dependent children. In order to determine the financial need of a family, ISI utilizes recommendations from School and Student Services (SSS), and requires financial documentation such as federal tax returns to be submitted annually. 

How to Apply for Financial Aid

1. Go to School & Student Services and create an account. The ISI school code is 4138.
2. Complete the application form, submit the required tax documents and pay the SSS application fee.
3. The ISI Financial Aid Committee will review the application and determine an award based on income, assets, taxes, family size, unusual expenses and circumstances and the number of family members in tuition-bearing schools.
4. You will be advised of the decision by SSS.

All information required is held in the strictest confidence.

We recommend you apply for Financial Aid concurrently with the ISI Admissions application. The ISI Financial Aid Committee considers applications after the Admissions decision has been made.

High School Tuition Lock

Beginning in the Fall of 2023, new and continuing ISI High School students can take advantage of a new program, the ISI High School tuition lock. In its first year, the new program will offer to lock in High School tuition for all new and continuing High School students, at the 2023-2024 tuition rate for each subsequent term, provided families meet the criteria and enroll in the program. 

ISI recognizes that tuition is an important factor when families select a high school. The school has taken several important steps to make attending ISI for High School a reality for more families, including participation in the Indiana Choice Scholarship Program, and generous aid packages for students in grades 9 to 12 with financial need. The ISI High School tuition lock program is another demonstration of the school’s commitment to strategic recruitment and retention efforts, and providing access to families of diverse socioeconomic backgrounds.

As rising costs for a broad range of goods and services weigh on families, ISI hopes fixed tuition costs for the duration of high school will eliminate uncertainty and provide peace of mind for families, and demonstrate the school’s dedication to preparing Upper School students and their families for college.
