Mission and Values

About Us

Rainier Prep is a 5th – 8th grade middle school in the Highline area focused on college prep for all students. Approved as one of Washington State’s first charter schools, Rainier Prep opened its doors for the first time in the fall of 2015.  Modeled on some of the highest-performing charter schools around the country, Rainier Prep is committed to college and career readiness for each of our students as our outstanding faculty and staff are transforming the expected educational outcomes for limited-income families, bipoc families, and immigrant families in our resilient community.

College Access

Access to a college degree is the single-most important factor in moving into the American middle class and fully participating in our democracy. While our nation’s public schools aspire to make college access possible, in reality, only 15% of children born to families who earn less than $47,000 per year currently earn a college degree. In contrast, 59% of those children born into families earning $142,000 or more earn a college degree. Rainier Prep will change these odds.

Leadership Development

The challenges of the 21st-century require a new set of skills and approaches from its leaders. Rainier Prep believes in the inherent ability of our students to meet these challenges and provide leadership in a changing world. Our school model is specifically designed to prepare diverse students to lead in our community and beyond.


GUIDES is an acronym for the values we expect Rainier Prep students, staff, and families to live by everyday. We strive to go beyond expectations and be daily GUIDES to each other as we seek to develop our students and achieve our mission of college graduation and life of leadership.
