Educate Girls, Empower Women

Our Sisters’ School opened in 2008 as a tuition-free, non-sectarian, independent school for girls from low-income families. In our 10th year, we continue to educate and inspire girls in grades 5 to 8 from the Greater New Bedford area to reach their full potential in a safe, supportive and challenging environment. The School’s name honors New Bedford’s storied history of women, called Sister Sailors, who joined whaling expeditions in the early 1800s.

Experiential and in-depth learning activities in our classes 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 and purposefully instill the confidence to be self-reliant and respectful toward others through our Core Values of Community, Citizenship, Leadership and Excellence.

  • 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.

Why all-girls? Evidence supports our belief that when you educate a girl, you educate the whole family and the next generation. We are moving forward with vision and determination to preserve the best of our history while embracing our future.

To celebrate 10 years, we invite you to join us in the PEOPLE, PROGRAM and PLACE campaign to invest in strategic initiatives that will ensure that our wonderful school continues to thrive for future generations of girls. Learn more about the 10th anniversary campaign.S
