Idaho

Past State Champions
Historically, St. Joseph's Catholic School has dominated Division B and Bishop Kelly High School has controlled Division C. However, in 2011 and 2012, Treasure Valley Math and Science Center won in B division, and in 2016, Capital High School dethroned Bishop Kelly. Treasure Valley Homeschool's Division B won two consecutive years in 2017 and 2018, and their Division C team has become a force, winning three years in a row from 2017 to 2019.
