International School of Indiana

What International School of Indiana does

International School of Indiana (ISI) is a private, independent, Pre-Elementary-through-Grade-12 school located on a unified 60-acre campus at 4330 N Michigan Road in Indianapolis. Founded in 1994 as a recommendation of a 1991 Indiana Humanities Council task force, the school served approximately 500 students across the 2024-2025 academic year and operates with a senior leadership team of a Head of School, two division principals (Lower School, Upper School), a VP of Advancement & External Relations, and a Senior Director of IT, Operations & Facilities. ISI's academic core is the only full-continuum International Baccalaureate offering in Indiana — Primary Years Programme (Pre-Elementary through Grade 5, authorized 2011), Middle Years Programme (Grades 6–10, authorized 2011), and Diploma Programme (Grades 11–12, authorized 2002) — layered with full language immersion in French, Mandarin, Spanish, and English from age 3 through Grade 3 and dual-language instruction in Grades 4–5.

The school's product surface extends beyond the academic core to include College Counseling (producing acceptances at selective U.S. and international universities), Athletics (20+ teams, >70% Upper School participation), Arts, Learning and Wellness Support, 40+ clubs and activities, before/after Enrichment & Childcare, a Summer Camps portfolio, and an International Student / Homestay Program administered in partnership with Cambridge Network. The underlying technology stack is pedagogical (IB framework, multi-age Early Years classrooms with 8:1 staff ratio) rather than software-centric; operational technology is delivered via Finalsite Enrollment/Billing, SchoolAdmin Parent Portal, Clarity for financial-aid needs analysis, and iVisitor Management for campus security.

Revenue is generated primarily through three published tuition tiers — General ($24,185–$26,959 for 2026-2027), Corporate ($27,690–$29,950), and International ($35,000 for Grades 6-12 inclusive of F-1, health insurance, and homestay) — billed annually or via 10-month/semi-annual payment plans. The Indiana Choice Scholarship voucher reduces effective K-12 tuition by 23–31%, and ISI allocates more than $2M annually to need-based financial aid processed through Clarity. Supplementary revenue streams include facility rentals, summer camps, ancillary fees, and philanthropic capital campaigns (ONE ISI, ONE Future — totaling $10.5M of committed investment through 2028). The school markets direct-to-consumer via isind.org, social channels, campus tours, virtual info sessions, and shadow days, with no third-party reseller channels.
