Welcome to Northstar Middle School! Northstar Middle School began in 1981 as one of Lake Washington’s first choice schools. Northstar has four full-time teachers and a student body of 90, with 30 students per grade level. At Northstar, we believe students learn best in a small, caring community where individual talents can be recognized and nurtured, academic growth encouraged, and moral development fostered. Each student will graduate prepared to lead a rewarding, responsible life as a contributing member of our community and greater society.
