School History

Riverstone International School was established in 1997 under the name Hidden Springs Community School. The mission of the school was to provide students in the Treasure Valley with a quality, independent education that focused on engaging and active learning, a commitment to the environment, and dedication to the school and local communities. Located just north of Boise, Idaho, Hidden Springs Community School opened its doors with 57 students enrolled in kindergarten through eighth grade. Since its opening, the school’s dynamic educational environment has continued to evolve.

Soon after the school began, word started to spread. In just three years, enrollment doubled. In 2000, the school moved from Dry Creek Valley to southeast Boise and changed its name to RiverStone Community School. With additional land to grow into, the school was initially housed in an old Forest Service building and three modular buildings.

By fall 2001, the school was accredited by the Northwest Association of Schools and Colleges and Universities (NASCU), and the State of Idaho. In that same year, school administration and staff began the rigorous authorization process that would permit the school to offer the highly respected International Baccalaureate Diploma Programme.

Wanting to develop a global student body, the school’s first international exchange students arrived in 2002. They came from Russia, Thailand, Germany, Brazil, Spain, Chile and Colombia. The following year, enrollment increased again with nineteen international students from countries including Austria, Chile, France, Germany, Korea, Kyrgyzstan, Mongolia, Spain, Thailand and Vietnam.

In 2004, the school was authorized to offer the IB Diploma Programme for grades eleven and twelve. In 2005, the school became an accredited member of the Northwest Association of Independent Schools (NWAIS) and our second graduating class became the first recipients of an IB Diploma in Idaho.

We changed our name to Riverstone International School in 2006, reflecting our commitment to an international student body and community — as well as a commitment to the International Baccalaureate Programmes. We had also grown to offer all grades, from kindergarten through grade 12.

In 2009, Riverstone was granted authorization to offer the Primary Years Programme and Middle Years Programme and began offering a dual language — Spanish and English — full day preschool. Athletic programs became formalized. We also defined our Five Pillars, which include academic excellence, community and service, leadership by example, international understanding, and outdoor education. Moving forward, the pillars helped ensure that students at every grade had opportunities to flourish and grow.

We were also the recipient of the Governor’s Brightest Star Award in 2009, in recognition of our service to the community.

Riverstone International School is one of a small number of schools in the United States that offers all three IB programmes:

  • Primary Years Programme (PYP)
  • Middle Years Programme (MYP)
  • Diploma Programme (DP)

In 2012, Riverstone was honored as Idaho’s only Malone Family Foundation School.

In 2016, we opened our dormitory, Riverstone House, and welcomed residential students in grades 9-12 to this beautiful downtown Boise facility. Sixteen students from seven countries comprised our first group of residential students.

This same year, we broke ground on Phase One of our new Middle and High School building. This new building will house two music rooms and three science classrooms, including a wet laboratory and dry laboratory.

We continue to grow and enrollment is currently at 350 students. Our students and faculty hail from six continents.

Throughout our history, the school community has remained committed to creating an environment in which students are known, supported, challenged, and encouraged to grow.
