One ISI 25 Anniversary

ONE International School of Indiana is the campaign that celebrates our
first 25 years and our vision for the successful decades to come.


Since 1994, ISI’s distinct academics – universal IB curriculum and 3-year-old-Grade 5 language immersion – have better prepared its students to be truly global citizens who are poised for professional and personal success.

As the school has ascended so too have the fortunes of Central Indiana, and ISI is proud to have played a vital role in helping Central Indiana foster a more inclusive values system that is at the heart of the state’s increasingly global economy.

This rich legacy is the foundation from which an ever-brighter future will be built as ISI realizes its vision for a unified campus with the construction of a new lower school building at its central campus on North Michigan Road by 2025.

ONE with our alumni, students and families. ONE with our community and facilities. ISI is Forever ONE.
