The school is organized into three divisions (Lower School, Middle School, Upper School) and uses a single-gender classroom model through Class 8, transitioning to co-educational instruction in the Upper School. Core academic programming is enhanced by a signature Public Speaking curriculum, individualized College Counseling (with 100% of Class 9 students assigned a counselor), Global Studies travel, a robust athletics program (32% five-year average of graduates recruited at the collegiate level), and 40+ annual arts performances and exhibitions. The institution is governed by a Board of Trustees, structured as a Massachusetts corporation, and led by Dr. Peter Folan, the fifth Head of School, installed September 2, 2025. The school reports 294+ faculty and staff plus 12 on-campus Teaching Fellows and is not publicly traded, with no venture capital, private equity, or parent-company ownership disclosed.

The product portfolio spans academic divisions (Lower, Middle, Upper School), signature programs (Public Speaking, College Counseling, Global Studies, New Venture Competition and Entrepreneurship), supporting infrastructure (Kraft Fieldhouse & Fusco Arena at 100,000 sq ft, Kraft Field, Veterans Ballpark, Dexter Southfield Squash Center, The Garage maker space, Gui Building), and ancillary offerings including the Teaching Fellows professional development program and the Dexter Summer camp (Classic, Enrichment, Premier Athletics). Technology is described as standard educational technology and learning management systems on the Finalsite web platform; no proprietary AI/ML models, APIs, SDKs, or partner-facing developer surfaces are referenced in any source.

Revenue is generated primarily through annual tuition under a subscription-style billing model (pricing not publicly disclosed), with diversification from Dexter Summer programs, online retail (SquadLocker and BSN Sideline Store for branded apparel and sports gear), and the Dexter Southfield Fund annual giving and capital giving programs. The go-to-market motion is direct-to-consumer via traditional private-school admissions (campus tours, admissions events, applications, and enrollment), targeting families in the greater Boston area; outreach extends through the school's website, organic social (Instagram, Facebook), email communications, campus events, and an active alumni and parent referral network. The customer base is the universe of 1,100+ day-student families, with no concentration in any single external enterprise logo.
