Upper School

Grades Nine - Twelve

Fostering Independence

The Gilman Upper School prepares young men to build the world of tomorrow. Students engage in a timeless and challenging college-preparatory program that emphasizes strong work ethic, critical thinking skills, effective oral and written communication, and lifelong enjoyment of intellectual pursuits.

Students must take five major courses each semester (English, mathematics, foreign language, lab science, history). They must also complete courses in art, music, and religion, participate in either interscholastic or intramural athletics, and complete 50 hours of community service during their Upper School careers. Advanced Placement (AP) courses are offered in numerous disciplines, and a coordinate program allows students to take courses at Bryn Mawr School (BMS) and Roland Park Country School (RPCS).

Educating the whole boy reaches beyond classroom learning. A robust leadership development program and special lectures, along with daily assemblies, bring real-world situations and applications to life. Our Device of Choice (D.O.C.) program enables boys to best utilize the skills necessary to learn in the 21st century. Various extra curricular activities give boys the chance to try almost anything in a comfortable and collegial environment.
