our top reasons to pursue an ib education



The International Baccalaureate (IB) programs aim to do more than other curricula. IB programs develop inquiring, knowledgeable and caring young people who are motivated to succeed. The IB gives students distinct advantages by building their critical thinking skills, nurturing their curiosity and their ability to solve complex problems.

The IB strives to develop students who will build a better world through intercultural understanding and respect, alongside a healthy appetite for learning and excellence.

ISI is the only Indiana school offering language immersion in three languages; French, Mandarin and Spanish. The focus is on developing fluency in speaking, reading, writing and understanding, so students can actively participate in their target language.

As there is no previous language experience required to attend ISI at any grade level, students who are new to language learning are provided specialized programming and attain language skills at a different stage to their grade level peers.
