You won’t find another school like ours in Indiana or even the Midwest. The combination of International Baccalaureate® (IB) programs, immersion and dual language learning in French, Mandarin, Spanish, and English, and enhanced cultural experiences make our academics distinct.
It is the smaller classes, personalized attention, and differentiated instruction that makes our approach to education so successful in preparing students to be inquiring, knowledgeable, confident, and caring young people ready for college and beyond.

athletics

At the International School of Indiana (ISI), we strive for balance in the lives of our students. We believe that body, mind, and spirit work best when they’re working together.

So, we offer over 20 athletic teams annually for students in grades 5 to 12, and joining a team is as simple as attending the first scheduled practice. Through our open participation policy, ISI provides athletic opportunities to all our students. Every student is encouraged to take part in athletics as a participant, team manager, or supporter.

Opportunities that go beyond the classroom give each student an ISI experience that is uniquely theirs. With a student population as diverse, self-motivated, and engaged as ours, it is not surprising that there’s so much to do. Students can participate in any combination of student activities, including fine arts, travel and field trips, and special-interest clubs. Many groups have been founded on the initiative of the students themselves.

Season Recap: Middle School Track & Field

The Middle School Track & Field team had an incredibly rewarding season. From the very beginning, one of the primary goals was to build a close-knit group of athletes capable of competing at a high level in both the PAAC and IISL. More importantly, the coaching staff sought to create a team culture built on support, hard work, and shared success. The athletes embraced that vision and did an outstanding job fostering a positive and competitive environment throughout the season.

Season Recap: Girls Varsity Tennis

After entering the season with a young and relatively inexperienced roster, the ISI Gryphons Girls Varsity Tennis team focused on growth, consistency, and building a strong team culture.

As the season came to a close, the Gryphons reflected on a year defined by more than standings and scores. “This season was defined not only by results, but by the friendships, growth, and memories our team created together,” Bougher said. The team's commitment to one another, combined with their on-court development, made the 2026 season one to remember.

Season Recap Varsity Track 2026

The Gryphons Track & Field program took important steps forward during the 2026 season. From athletes setting personal records to strong performances at sectionals and regionals, the team showed steady improvement throughout the year. While injuries presented challenges along the way, the Gryphons remained committed to their goals and continued to compete with determination, making this season another positive chapter in the program's growth.

Timmy Club Supports the ONE Future Campaign

On May 22, members of the school’s Timmy Club and the Boys Varsity Volleyball team hosted a special event in support of the ONE Future Campaign: the Boys Volleyball vs. Alumni & Staff Timmy Game.

The Timmy Club not only organized the event but also made an impressive $1,500 contribution to the campaign. Through the combined efforts of students, staff, alumni, and parents who participated, attended, and donated, the event raised an additional $1,200, expanding the club’s combined impact to $2,700.
