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.
