School Notes

Seattle Prep is a Catholic, college preparatory school.
Faithful to Jesuit tradition, our mission is the development of young men and women in the processes of learning to learn, learning to live and learning to love.
We recognize the prophet Micah's call to “act justly, love tenderly and to walk humbly with our God” for the transformation of ourselves and the world.
Since 1891, Seattle Preparatory School has instilled in young hearts and minds the values inherent in the Jesuit educational tradition.
Prep has graduated over 8,000 young men and women who have applied Jesuit values to achieve thoughtful and compassionate leadership in commerce, government, Church and family and in service to their country and community.
Prep's commitment to academic excellence, spirituality, diversity, access, community, inclusiveness and leadership must be constantly examined in light of how those values can be achieved in a changing world.
We are committed to providing our students the very best teachers, programs, opportunities and facilities to support students in their achievement of the excellence that is the hallmark of a Jesuit education.
