Gould operates on a trimester system, and students typically enroll in five to six courses per trimester. Class periods are affectionately known as "dots" (periods), and have a fixed schedule changing between four and three classes a day. The fall and spring term schedules include a half day every week on Wednesday, a late start every Thursday, and occasional Saturday classes. The Winter term schedule is based on half days Tuesday through Friday to make time for athletics, mainly the On-Snow Competition programs.
