The loss of identity based on their local high school was a challenge which many small communities did not survive.

The school is on a 45-acre (180,000 m2) fenced campus on the outskirts of Sherbrooke in viewing distance of Bishops University and Lennoxville.

It was constructed with concrete blocks and red brick in a Celtic cross-shape, nestled in a depression with a surrounding roadway level with the second floor.

Part of the building (one wing) is used by the Eastern Townships Technical Institute — a vocational education center.

The smaller gymnasium contains a rock climbing wall, a half-size basketball court, and a fully equipped weight training room.

The cafeteria has a seating capacity of 1,000 people and serves hot lunches every day to students for a fee ($5.00).

The library offers its students access to its 28,000 books and 14 computers, with racks of laptops left over from the Enhanced Learning Strategy (ELS).

The courses and programs at AGRHS include Drama, English language arts, English-History (Enriched Literature and Canadian Studies), Ethics and Religion, French language, French Geography, History, Contemporary World, Contemporary World and Literature, Home Economics, Mathematics, High Mathematics (Science or Technical Science), Integrative Project, Media Literacy, History of the 20th Century, Advanced Music, Multi-Sport, Music, Physical Education, School Community Service (Community Skills), Sciences which include Chemistry and Physics, and Spanish.

Additionally, activities are offered to students who sign up for the related courses in Band Concerts and Drama Play.

The school sometimes requests a few of the more distinguished players from the rhythm section (usually a drummer, a bassist and one or two guitarist) to play songs of their choice for the general public, usually for open houses and such gatherings.

Every year features a year-end concert where everyone in the band program is invited to play for the general public with their respective grade.
