High School Coordination

Greenwich Academy and the neighboring all-boys Brunswick School have a unique, coordinated Upper School relationship. At its simplest, Coordination means that GA and Brunswick students can each take classes at the other’s Upper School.

But this nearly 50-year partnership offers worlds more. Scholarship, camaraderie, performance, sport, lunch—the opportunities for our two student bodies to learn with and from each other transcend and transform all manner of spheres. Coordination makes it possible for GA girls to benefit from an incredible array of resources—physical, intellectual, social—while still enjoying the benefits of a small-school, all-girls environment. As so many members of our community will attest, it truly is the best of both worlds. 

In the Classroom

Academically, Coordination unites GA and Brunswick as one: Both high schools maintain the same calendar and daily schedule, and students select classes from a single catalog. While this allows an exciting array of course options—fiction writing! environmental history! infectious diseases!—it also enables each high school to smartly target resources: GA owns chemistry, Brunswick has physics. Together, we can offer more than 80 honors and AP classes and more than 200 academic and arts courses overall. Yet we are also mindful of what brings families to GA in the first place, the unique, enduring, and documented benefits of all-girls education. With that in mind, all math and computer science classes are single sex, as well as ninth grade English. 

On Stage

Every year, GA and Brunswick join forces for four stage productions, two plays and two musicals. These efforts combine considerable student talent with dedicated leadership which results in arguably dazzling events that are inevitably highlights of the school year. The collective GA memory still hums with recent productions of Mamma Mia! and Hairspray.

After Class

GA and Brunswick share many extracurricular activities, from proms to sports, but our joint, Peer Leadership Program is perhaps most emblematic. Each year, 18 senior girls and 18 senior boys are selected to lead freshman orientation. Every fall, on Orientation Day, the entire 9th grade from both schools gathers on campus to meet, greet, and be put through their paces by their peer leaders, a senior girl and boy. The groups continue to meet weekly throughout the fall, for discussion and activities, for sharing and support, for friendship and camaraderie. For freshmen, Peer Leadership is a helpful welcome to the new, co-ed environment. For seniors, it’s a chance to pass along the benefit of their experience, to help younger counterparts, and to lead with care, understanding, and character.
