Understanding Tuition and Fees 

The cost of educating an ISI student exceeds our tuition amount by several thousand dollars. We cover the difference for all families by relying on philanthropic support from individual and corporate donors. ISI also participates in the Indiana Choice Scholarship Program, known widely as the "Voucher" program. For qualifying ISI families, vouchers can reduce tuition costs by approximately $6,100 to $7,500 per student per school year.

To help families plan, ISI publishes tuition and fee schedules for the following school year by January, along with a breakdown of additional costs for programs such as child care, enrichment, athletics, and exchange trips.

Financial Aid

Families should carefully review tuition and fees and assess their ability to cover educational costs. Those who anticipate needing financial assistance should apply when submitting their admission application. Requests made after admission will generally only be considered if a family experiences a significant, unexpected change in circumstances, such as a job loss.

Financial aid is awarded based on demonstrated need, using factors such as household income, assets, family size, and tuition obligations for other children. ISI uses Clarity to evaluate need and requires updated financial documentation, including federal tax returns, each year.

Award decisions also consider factors such as academic achievement, diversity, community contribution, and enrollment demand for specific grade levels and language tracks. Families may appeal a financial aid decision by contacting isifinancialaid@isind.org.

High School Tuition Lock

The High School Tuition Lock program locks in tuition rates for all new and continuing High School students, at the time of enrollment for each subsequent term, provided families meet the criteria and enroll in the program. 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.
