The Cambridge School of Weston

What The Cambridge School of Weston does

The Cambridge School of Weston (CSW) is a private, nonprofit, coeducational day and boarding school serving grades 9-12 plus post-graduate students on a 65-acre wooded campus at 45 Georgian Road, Weston, Massachusetts. Founded in 1886 and legally organized as The Cambridge School of Weston, Inc. in Massachusetts, the school enrolls roughly 315 students and operates a gender-inclusive, sales-led admissions model (inquiries, campus visits, school fairs, and an enrollment workflow managed through Ravenna Solutions). Eighty percent of faculty hold advanced degrees, and the curriculum is delivered through a proprietary Module System — six six-week academic modules per year, each composed of three 90-minute daily class blocks — that supersedes the conventional semester model and enables curricular experimentation.

The school's product set centers on the Module System and four signature programs: the Social Justice Requirement (mandatory 10+ courses examining power, equity, and non-Western perspectives), Place-Based Learning with international Mod Abroads to France, Taiwan, Panama, and Japan, a Marine Biology program on Hurricane Island, Maine, and PACE (Promoting Awareness and Community Engagement). The technology stack is conventional SaaS — myCSW (built on Blackbaud's mySchool platform), Blackbaud Raiser's Edge NXT for fundraising and alumni management, MailChimp for email, and Homeroom for events — with no disclosed proprietary AI, ML, or platform-level differentiation.

Revenue is generated through four streams: tuition and fees (annual billing for day and boarding students), the CSW Fund (annual giving), endowment income, and planned giving (bequests, charitable trusts, annuities). Specific tuition figures and overall revenue are not publicly disclosed. Distribution is direct and campus-based: outreach via the website, social channels, and regional school fairs drives prospective families to campus visits and open houses, after which enrollment is executed through the Ravenna-powered admissions system. The institution is governed by a Board of Trustees with no parent company, private-equity, or venture ownership; the customer base is the 315-student cohort plus their families, with reported 100% college placement at selective institutions including Cornell, Dartmouth, NYU, Bowdoin, Tufts, and Northwestern.
