Riverstone International School

About Us

Riverstone International School is a co-educational, private, independent school in Boise, Idaho offering our day and residential students the academic prestige of the International Baccalaureate Programs and the personal attention of a supportive community school. We believe strong student-teacher relationships are the foundation for academic success and personal growth, so we purposefully keep classes small, with fewer than 18 students.

Engaging classroom discussions continue when students explore Idaho’s mountains and deserts with classmates and teachers. Fall back-to-school backpacking trips into the Sawtooth Mountains, winter snow camping, and five-day backpacking trips in the spring are highlights of our students’ time at Riverstone. We offer concierge college counseling, including a four-day college tour in grade 11 and individual support throughout high school.

Extracurricular activities include athletics, music groups, and academic teams. Our sports teams include girls volleyball, girls and boys basketball, girls and boys soccer, ski/snowboarding, and swimming. Music ensembles and academic teams for science, robotics, and humanities round out our students’ time out of the classroom.

One hundred percent of graduates are accepted into 4-year colleges worldwide. The Classes of 2017 and 2018 acceptances include Brown University, Bates College, Boston College, Princeton, University of Chicago, and the Universities of California, Rensselaer Polytechnic Institute, Tufts University, among others. Our most recent two-year International Baccalaureate pass rate exceeds the United States and international pass rates.

Our newly-built residential facility is located in downtown Boise, the third most populous city in the US Pacific Northwest, with easy access to skiing, kayaking, and mountain biking. Our residential coordinators will help students explore all that our beautiful city has to offer. Boise is one of the safest cities in the US and accessible via a direct flight from Seattle, San Francisco, Los Angeles, Denver, and Chicago.

Riverstone International School is a perfect place to hone your academic skills and expand your horizons! Adventure awaits!
