Our Schools

Our network is made up of two great campuses, Sage International Boise and Sage International Middleton. Our Boise campus began with a simple idea – parents and children need a different option than the education they could find at other area schools. Our parents want 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. The Sage Middleton campus has enrolled 400+ students in Grades K-10 and is still growing. It is authorized to offer the IB’s Primary Years Programme (K-5) and is a Candidate School* for the Middle Years Programme (6-10). These are schools that share a common philosophy—a commitment to high quality, challenging, international education that Sage International Middleton believes is important for our students.

We are Public Charter Schools

Sage International Schools are public charter schools, meaning they are tuition-free schools of choice. We are K-12 (or growing to K-12) public schools. Inquiry-based learning creates caring and curious students who ask questions and are equipped to solve big problems. Your child can start here in Kindergarten and graduate high school from our Sage Network!

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

Ou Mission

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 education.

Take a moment to view the short video below. These are testimonials from IB graduates from around the world sharing how the program altered the course of their lives. Your child could have a similar story to tell years from now.
