Middle School students have the opportunity to participate in a variety of clubs and activities that meet during the school day and after school. Some students prefer to participate in these clubs one or two days a week after school, whereas others are involved every day. Activity offerings include but are not limited to: Art Squad, Rocketry, Role Playing Game Club, Studio (homework help), Esports Club, Fiber Arts Fun, Ceramics, Friday Afternoon @ The Movies, Friendly Fridge, Magic the Gathering, Debate, Stock Market Club, Vex Robotics, Dance Company, Computer Science Club, Student Council, Storytelling Club, Tech Crew, Yearbook, Math Team, and Model Government.
Upper School students can choose to join a couple of clubs if they choose. There are designated Activity periods during the school day so students do not need to choose between participating in a club/activity and joining an athletic team or participating in the theater program. Activity offerings include but are not limited to: Yearbook, Math Team, Riverdale Community Partners, Riverdale Criminal Justice Coalition, Robotics, Girls Who Code, Challenged Athletes Foundation, and Animal Welfare Club. Students are welcome to propose new clubs.
