The International School of Indiana (ISI) is a vibrant, inclusive learning community that offers students from 3 years old through Grade 12 an experience they won’t find anywhere else: a dynamic framework for understanding other cultures and perspectives.

We are proud to be the only Indiana school offering the globally recognized, full-continuum International Baccalaureate (IB) curriculum to all students, and the only Indiana school offering immersion and dual language programs in French, Mandarin, Spanish, and English.

ISI delivers exceptional college counseling outcomes, guiding students toward successful admissions to prestigious universities worldwide. With a focus on personalized support and comprehensive preparation, the ISI college counseling program equips students with the tools and confidence needed to navigate the competitive college admissions landscape.

Step into a world of limitless educational excellence at ISI, where the renowned International Baccalaureate (IB) curriculum isn't just an option for the select few – it's the heartbeat of our educational journey for every student. From the IB Primary Years Programme, igniting minds from as young as 3 years old, to the rigorous challenges of the Middle Years and Diploma Programmes in grades 11 and 12, ISI offers a transformative continuum unmatched across Indiana.

With every educator trained in the IB framework, our students are equipped to excel beyond the global benchmarks set by over 5,000 IB World Schools in 156 countries. At ISI, education isn’t just about meeting standards – it’s about unlocking potential and fostering a passion for lifelong learning.

ISI offers more than 40 clubs and extracurricular activities for students each year.

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 and groups, including fine arts, travel and field trips, special-interest clubs, and athletic teams. Many groups have been founded on the initiative of the students themselves.
