Program Overview

Extended School Day: Our 11-hour school day begins at 7:30 AM and ends at 6:15 PM.  Academic instruction is interspersed with fitness, sports and extracurricular activities.  Study hall rounds out our day; during this time students may receive academic coaching to bolster their success.

Philosophy: Our Sisters’ School believes that students benefit from an extended school day, small class size, experiential learning opportunities, inspirational speakers, advisory and physical activity incorporated into the school day.  From entrance in grade 5 to the completion of grade 8, students typically reach or far exceed their grade level in reading and math testing as specified by Stanford 10 Testing. Our Sisters’ School employs GMADE and GRADE assessments twice annually to monitor individual student achievement.

Academic Courses of Instruction: All students at Our Sisters’ School participate in the following academic courses: Humanities (incorporating social studies and English language arts), Science and Math.

Extracurricular Programming: Our Sisters’ School students are provided with additional courses including: creative writing, construction, foreign language, health, music (flute, piano, clarinet, guitar and chorus), public speaking, visual arts, advisory, robotics, internship programming, debate and chess.

Fitness:  All of our students participate in fitness and yoga.

Sustained Silent Reading (SSR): All students and staff read for 45 minutes each day in a silent school atmosphere. Modeled after research and work done by Stephen Krashen, Janice Pilgreen and others, we are seeing gains in reading fluency and levels for all students.

Experiential Learning: Our Sisters’ School students learn to sail through an educational partnership with the Community Boating Center of New Bedford. The Buttonwood Park Zoo, The New Bedford Symphony Orchestra, The Lloyd Center for the Environment, and the Youth Opportunities Unlimited organizations also provide frequent and consistent hands-on learning experiences for all students through their science and art classes.

Clubs and Internships: Chess, knitting, stained glass making, tennis, cheerleading, basketball, quilting and cooking are just a few of the club opportunities open to students during the week. Internships at the Whaling Museum, the Buttonwood Park Zoo, and the Immigrant's Assistance Center are also available to students.

Advisory: All students and staff participate in advisory activities, where Community Core topics designed to enrich the community’s social and emotional growth are practiced.

Community Meeting: This all-school gathering occurs twice weekly. It is a place for announcements, appreciations, celebrations, and songs. Positive role models and leadership opportunities are encouraged and celebrated.

Morning Speaker: Our mission is not only to educate but also to inspire our students.  They hear inspirational life stories from members of the greater New Bedford community twice each week.

Parent Involvement: Parents participate by supporting staff through attendance at academic conferences, monthly PTO meetings and by completing required volunteer hours.

Community Service: All students are required to participate in community service activities. They complete between ten and fifteen hours annually.
