- School Motto: 'Fostering independence, self-esteem, and a lifelong love of learning.'
- The Ocean State Montessori School is the oldest Montessori school in Rhode Island. It was founded in 1973 by a group of parents interested in the Montessori Method. They secured a grant to purchase Montessori materials and hired a teacher and two assistants to teach 30 students in a church in Barrington. Over the years the school has expanded, adding additional Montessori classrooms and programs.

The Ocean State Montessori School is licensed by the Rhode Island Department of Education and the Rhode Island Department of Children, Youth and Families.We arean affiliate member of the American Montessori Society (AMS). Our teachers all hold bachelor`s or master`s degrees and have received, or are in the process of earning, their AMSteaching credential.

Our classrooms provide this "prepared environment" in which children are free to explore and learn at their own pace. Each classroom has a full component of Montessori materials. The teacher acts as a guide to the classroom, recognizing periods of readiness, introducing new materials and demonstrating how to use them.

I love OSMS! My child has been in the primary classroom for a year and a half, and is absolutely thriving. The teachers are wonderful, and the school community is small enough and caring enough that everyone knew my kid's name within a week. The Montessori philosophy is executed flawlessly here, and it's beautiful to see the individual attention that each child receives, as well as how their independence is encouraged and nurtured. I'm so grateful for this school!

We've had an excellent experience at Ocean State Montessori. The teachers are nurturing and dedicated, the Montessori philosophy is thoughtfully applied, and both of our children have flourished in this environment. Highly recommend this wonderful school.

Our family has been involved with the Ocean State Montessori School community for 2 years now, and we love it! As parents, we knew we wanted our child to get a Montessori education, and the fact that OSMS goes until 6th grade was a huge draw for us. So far our child has been loving their experience, and we can already see the ways the routines in the classroom, the care for the other students, and the dedication the teachers have to our child's growth are showing up at home. Our child's teacher is always available to check in and gives us updates that are more than just "good or bad." Since the format is that students stay with the teacher for three years, she has really taken the time to get to know our child and sees genuine moments of growth and development. We are excited to watch our child flourish throughout their years there.

Parent of a child that attended from age 3 to sixth grade. Our child found OSMS to be a perfect fit for his social & emotional growth needs. OSMS helped him develop independence and self-awareness in a supportive environment surrounded by people who genuinely cared for him.

You could not ask for a better educational foundation for the preschool and elementary school years. The teachers are fully invested in their students and the Montessori approach to education has given each of my children confidence in their abilities while motivating them to achieve even more because they love learning. After graduating from OSMS, my older child had a smooth transition to 7th grade (in a traditional public school) and has excelled in high school. The community provides a welcoming and nurturing experience to the students and their family.

Our 2 children have been part of the OSMS learning community for the past 13yrs. Each and every year we are happy and excited for our children to continue their love of learning with the OSMS faculty and staff. We have a choice of where to send our kids, we choose the Ocean State Montessori School.

Over the least 7 years, we've watched as our son grow creatively, socially and academically in the nurturing OSMS community. The faculty and staff are caring, intelligent individuals that support, challenge and grow the kids in every way. I'm looking forward to what the next three-year cycle will bring in Upper Elementary.In short, we love it!
