Classes run from Monday to Saturday, beginning at 8:00 am and ending at 3;10 pm. Wednesdays and Saturdays are half days with students ending at 1:45 pm and 12:15 pm, allowing for more time to contribute to athletics, volunteer work, clubs, and independent studies. Many courses offered at Peddie are full-year courses, running from Fall to Spring term. Many electives run for one to two terms, allowing students to take multiple different courses throughout the year. The majority of students take five courses each term. A select few students take six or seven courses at a time.

Additionally, Peddie students are required to participate in after-school activities throughout the year, including sports, theater productions, volunteer opportunities, and clubs. Students can request to have a course formed if they have a faculty representative and have demonstrated interest in the subject. Peddie offers 34 subjects for Advanced Placement (AP).
