The Middle School program at Charles River School is outstanding for its focus on academics and on individual student support and development.

At CRS, our middle school students:

  • Learn how to think abstractly and receive highly-personalized feedback across all academic disciplines (math, social studies, English, science, world language);
  • are nurtured in a close-knit environment free of social pressure, enabling them to embrace their own individualities and readily accept others as they are;
  • benefit from close monitoring of behavior and swift, direct attention to problems with the involvement of all parties;
  • develop close relationships with their advisors, who meet with them one-on-one to nurture academic, social, and developmental growth;
  • lead the student community, and set positive examples for their younger peers;
  • choose from a variety of electives and after-school activities, including sports, Model UN, Mathcounts, Speech and Debate, rock climbing, chorus and more;
  • are extremely well prepared for any secondary school they may choose to attend, public or private.
CRS faculty and staff are committed to the success of all students. Together, we set the bar high for their social, moral and intellectual development. And together, we provide them with the time, resources and steady guidance they need to achieve their personal best.


Mathcounts at CRS has become so popular over the years that it is both a club and an elective. Students in Mathcounts Club solve a set of ten problems each week and then meet over lunch to discuss and compare solutions. Students who choose to take Mathcounts as an elective on Friday afternoons tackle more difficult problems and learn additional advanced math concepts.  Members of the elective compete in the Metro-West chapter competition in February each year.

Model United Nations

Model UN (MUN) allows students to attempt to resolve real-world problems using the UN’s structure and rules of procedure.  In preparation for a MUN conference, student delegates work in teams to prepare draft resolutions that accurately reflect their assigned country’s position on a current issue.  Club meeting also review negotiation techniques, conflict resolution strategies, and public speaking skills. Students in MUN participate in a regional conference at Northeastern University and an international conference held in New York City at the United Nations Headquarters.
Charles River School is a PreKindergarten through Grade 8 independent school that honors the pursuit of academic excellence and the joy of childhood. We nurture each child by igniting curiosity, encouraging creativity, and cultivating intellectual engagement. Our graduates know themselves, understand others, and shape the future of our diverse world with confidence and compassion.
