Our Mission is to inspire and develop courageous leaders who think independently, work collaboratively, learn joyfully, and champion change.
Our Passion is empowering each girl to live her potential.
Our Beliefs: Empowering a girl changes the world. It is fundamental to understand and address issues of difference and oppression.
An integrated, collaborative curriculum challenges and engages students. Middle school should be joyful, curiosity-filled, and safe and open to all voices.
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!
