Tri-School Coordinate Program

The logo for the TriSchool Coordination Program.

Perhaps the most unexpected characteristic of our community is that this all-boys school also includes girls as classmates.

Coordinate classes, begun in 1974 with The Bryn Mawr School (BMS) and later expanded to include Roland Park Country School (RPCS), offer the best of both worlds: single-sex education combined with co-education in the junior and senior years. The coordinate program allows students to choose from a wide array of classes unmatched by any single high school.




Our coordinate program allows Upper School students to take courses at nearby Bryn Mawr School and Roland Park Country School. The program provides a wider array of courses from which students can choose, with selections available in English, mathematics, German, Russian, Chinese, science, history, art history, and visual arts. Pedestrian bridges connect Gilman to the other campuses for safe and convenient access.
