Logo Welcome to Athletics at Mount Si High School 

Mount Si High School has a long tradition of excellence in the competitive KingCo league and at the state level.  Mount Si High School competes at the 4A level.  Together with our staff, parent boosters, and community we are proud of our athletes on and off the field.  Go Wildcats!
All student-athletes must go through the clearance process to determine eligibility before the first practice or tryout. Athletes need to be cleared for each sport, even when playing multiple sports within the same school year.
