Welcome, and thank you for your interest in Sage International School!

Our Mission: Sage International School engages students within an inclusive International Baccalaureate® (IB) learning community, challenging all members to take risks and contribute locally and globally through open-minded inquiry. 

Our Curriculum is rigorous, balanced, and broad. We develop a strong foundation in early math and reading, offer French at every grade level, and develop critical thinkers. Our inquiry-based model creates caring and curious students!

The IB offers a unique educational experience designed to create passionate world citizens that engage locally and globally. It challenges and motivates students academically and personally. Sage inspires a lifelong quest for learning, infused with enthusiasm and empathy. In addition to supporting academic development, the IB addresses students' social, emotional, and physical well-being through the IB Learner Profile. 

We are the only public school in Idaho offering students in K-12th grades a free, public education modeled on the globally renowned IB curriculum. We are also one of only 3 IB World Schools nationwide to offer all four of IB's K-12 educational Programmes!

Enrollment for the 2022-23 (CURRENT) School year:

Sage conducts a lottery each spring to fill any open seats we anticipate for the next school year. We have current openings in some grade levels, and you can see waitlists for each grade via the link to the left. We invite you to apply via the link to the left or by clicking here. You will receive a confirmation email from our registrar either with an offer or to let you know that your student has been placed on the waitlist.

Whether we currently have seats available or if it places you on our waitlist in the event that grade is full, we have movement in our waitlist throughout the school year as plans change for families. Our lottery is just the start of enrollment season, and we'd love to keep in touch!
