Lottery Process

For the International Baccalaureate program at Mount Rainier High School, up to 15 seats per graduating year will be reserved for each of the high school service areas (Highline, Tyee and Evergreen). If more than 15 students apply from each service area, a lottery system will be implemented. 

If there are more applications than space at any particular grade level, Highline will hold a lottery including all students with completed applications. Students not accepted in the lottery will be placed on a waitlist in the order they are chosen from the pool of remaining students. If there are more seats available than there are applicants, applications will continue to be accepted on a rolling basis throughout the year.

  • The lottery will take place on March 1.
  • Families will be notified immediately via SchoolMint.
  • Full results will be posted on the website on or before March 3.
