Greenwich Academy is an all-girls school. Brunswick School, just across town, is all-boys. For more than 50 years, the two schools have run a formal Coordination program that lets Upper School students share classes and activities across both campuses, without either school changing its single-sex enrollment.
Quick Answer for Busy Parents
The Coordination program is a decades-old partnership between Greenwich Academy (all-girls) and Brunswick School (all-boys) that combines course catalogs, activities, and theater productions for Upper School students at both schools, giving GA students access to a coeducational academic and social experience without changing the school’s single-sex structure.
What the Coordination Program Is
At the Upper School level, Greenwich Academy and Brunswick School combine their course catalogs, extracurricular activities, and theater programs, allowing students from both schools to take classes, join clubs, and participate in productions together. It’s a structural answer to a question many families ask about single-sex schools, one connected to broader social-emotional development: how do students get a coeducational social and academic experience without the school itself going coed?
How It Works Day to Day
In practice, the Coordination program shows up most visibly in the Upper School’s course catalog and theater program: GA and Brunswick students can enroll in select combined classes and audition for joint theater productions, alongside their home school’s own extensive offerings; GA’s Upper School alone lists 277 courses.

Weighing Single-Sex vs. Coed Options?
Cardinal Education helps families think through how a school’s social structure fits their daughter’s needs.
Why This Model Has Lasted 50 Years
A partnership surviving five decades suggests something more durable than a marketing arrangement: both schools have found a genuine way to preserve the academic and developmental case for single-sex education (which research and many families still find compelling) while addressing the social dimension that a purely single-sex environment can’t offer on its own.
Why This Matters for Families Considering Greenwich Academy
Families evaluating an all-girls school often want to know whether their daughter will have a well-rounded, socially balanced high school experience. Greenwich Academy’s answer isn’t informal or occasional; it’s a structured, half-century-old partnership specifically designed around that question. For families who value the case for single-sex education but don’t want to give up coeducational social and academic opportunities, the Coordination program is a concrete, long-standing answer, worth understanding alongside what schools look for in applicants more broadly.
Stand Out in Greenwich Academy Admissions with Cardinal Education
The Coordination program is one of the most distinctive features of Greenwich Academy’s model: single-sex academics with a genuine, decades-old coeducational partnership built in. Cardinal Education’s private school admissions consulting helps families understand how that balance fits their daughter’s specific needs alongside GA’s admissions requirements.
