Lake Washington Girls Middle School is a place where girls explore, experiment, discover, create, and learn about themselves and the world around them.

LWGMS challenges each student with high standards and helps every student find the tools she needs to succeed. Here, girls are empowered to think critically, develop leadership, and enjoy learning through an integrated curriculum that has proven to prepare girls for success in high school honors and college preparation courses.

The LWGMS curriculum presents girls with multiple perspectives that encourage them to form – and articulate – their own opinions.

Our cooperative, experiential, holistic education supports girls throughout their middle school years - academically, socially, and emotionally. We have small classes, caring teachers who work with students as they move from sixth through eighth grade, and strong parent and community involvement.
