  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!
