Welcome to Our Sisters’ School (OSS) where we educate and inspire girls in grades 5 through 8 from the Greater New Bedford area. Our dedicated teachers engage students in meaningful classes that are interdisciplinary, social justice oriented, place-based, community and project-focused and fun.

Strong academics are coupled with positive character development as students explore our Core Values of Excellence , Community, Civic Engagement and Leadership with a growth mindset. Our graduates demonstrate the power of an OSS education as they thrive in their high schools, colleges and beyond.
