Our School

Sage International Schools began with a simple idea – parents and children needed a different option than the education they could find at other area schools. These parents wanted an international education, a rigorous learning environment, authentic teachers and a school that embraced innovation and change.

The Sage International School of Boise opened in 2010 with 211 students. By 2014, there were nearly 900 in Grades K-11. Today our Boise campus routinely enrolls 1000 students in four different International Baccalaureate (IB) programs in Kindergarten through 12th grades. Sage-Boise is one of only three public schools in the United States that offers all four IB programs.

In 2019, the Sage International Network of Schools opened a second campus in Middleton, Idaho. Middleton is a lovely and lively community that is in the rapidly growing area of the western Treasure Valley of Idaho. By the start of the 22-23 school year, the Sage-Middleton campus had enrolled 400+ students in Grades K-10 (growing to K-12). It is authorized to offer the IB’s Primary Years Programme (K-5) and is a candidate for the Middle Years Programme (6-10). As it continues to grow, our Middleton campus will offer the Diploma and Career-related Programmes for Grades 11 and 12.

We are Public Charter Schools

Sage International Schools are public charter schools. They are tuition-free schools of choice. We are the only public schools in southwestern Idaho offering a full continuum of International Baccalaureate programs. We are K-12 (or growing to K-12) public schools. Your child can start here in Kindergarten and graduate from the same school.

“Public charter schools are unique public schools that are allowed the freedom to be innovative while being held accountable for advancing student achievement…”

We are International Baccalaureate Schools

Our schools’ mission encourages us to ask questions; to be inclusive; to form a community of learners and to engage with our world – both locally and globally. We believe in our schools’ mission and we think the best possible way to encourage the broadest numbers of people to make a difference locally and globally is through an International Baccalaureate education.

Take a moment to view this short video – these are testimonials by IB graduates of different ages telling the audience how the program altered the courses of their lives. Your child could have a similar story to tell years from now.
