Making Waves

What's Happening at OSS? We are making waves in the education of middle school girls. Click here for recent school news stories and pictures!

Educate Girls, Empower Women

Our Sisters' School opened in 2008 as a tuition-free independent school for girls, in grades 5 to 8, from low-income families. Our mission is to educate and inspire middle school girls from the Greater New Bedford area to reach their full potential in a safe, supportive and challenging environment. We have no religious affiliation. We are named after a few bold, brave women called Sister Sailors who joined expeditions on whaling ships in the early 1800's.

Experiential learning activities both in and outside the classrooms help our students develop excellent skills for success in high school, college and beyond. We offer many opportunities for girls to be leaders in the school community and continually strive to build self-esteem and respect for others.

  • 33% of our alumnae attend independent day and boarding schools with full scholarships.
  • 50% of our graduates choose to attend the local vocational technical high school.
  • 17% of our alumnae attend local public schools.
  • All of our graduates are college bound.

Our Sisters' School is 100% privately funded and relies on the generosity of our donors. Massachusetts law prohibits state funding for single-sex education, yet many families prefer an all girls learning environment for their daughters during middle school. Evidence supports the fact that when you educate a girl, you educate the next generation. We are doing just that!
