Seattle Girls' School

OUR MISSION is to inspire and develop courageous leaders who think independently, work collaboratively, learn joyfully, and champion change.

Middle school is a critical time for development - especially for girls. As girls reach early adolescence, their self-esteem and interest in certain subjects is likely to plummet as a result of being bombarded by conflicting messages about femininity and achievement.

Seattle Girls’ School combats the trend of girls losing confidence before competence, especially in the areas of science, technology, engineering, and math, with a transformative experience for girls in grades 5-8. At SGS, girls are challenged to discover who they are and who they want to become. Our project-based curriculum, grounded in real-world experiences, offers endless opportunities for leadership, collaboration, and problem solving.

We invite you to witness what countless visitors to our campus experience: poised, confident, and actively engaged students. Our alumnae, when reflecting on their educational experience as a whole, often attribute who they become and what they achieve to the transformative experiences they had at SGS - their middle school!

WEDNESDAY WORKSHOPS: We partner with local organizations like Skate Like a Girl, School of Acrobatics and New Circus Arts (SANCA), and Coyote Central. They include workshops such as Podcasting, Cooking, Rock Band, Woodworking, Graphic Arts, and Dance.

AFFINITY GROUPS: SGS students have the option of participating in school-based affinity groups to explore their ethnic, cultural, or sexual identity with the support of peers, faculty, and staff. Affinity and Alliance Groups meet monthly during school hours.

STUDENT INTEREST GROUPS: SIGS are created by students seeking an outlet for specific activities or interests. Led with the help of a faculty advisor, past SIGs have included Art SIG, Writers SIG, and Garden SIG, Coding SIG, and IMPUHWE.

MENTOR PROGRAM: The goal of the Mentor Program is to make our students “strong from the inside out” by building a village around each girl. The unique experiences and insights that each student gains by having a mentor enhances her education at SGS.
