School Notes
- 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!
