A World-Class Private High School, Right Here in Indianapolis
ISI High School combines the best aspects of a private high school with the advantages of a four-year International Baccalaureate program. It’s a challenging, multicultural program with small class sizes and a community atmosphere. ISI understands that high achievement must be balanced with creativity, fun, and self-reflection.
ISI High School accepts students in any year up through Grade 11 (but not in Grade 12, because the IB diploma cannot be completed in just one year). Though we are a language-rich school with an international focus, students do not need to speak a foreign language to attend. Our language specialists can give individualized attention to high school students who need it, in order to accelerate their language learning.
