The school is run under the guidance of the Episcopal Church, and offers the International Baccalaureate Diploma Program.

The International Baccalaureate (IB) is a nonprofit foundation headquartered in Geneva, Switzerland, and founded in 1968.

The school is known for its annual intramural basketball game, a tradition that began in the 1890s when co-headmistresses Polly and Sally Carter divided the students into two teams named "Brownie" and "Spider".

The game has been played each year according to the original three-court rules, with players wearing 19th-century tunics.

Equestrian facilities include: an indoor arena with 28 stalls and new premium footing, two tack rooms, and wash stalls; an outdoor riding ring with sand and fiber footing; and indoor ring; four private paddocks; and seven large fields - three with run-in sheds.
