Calhoun Middle Schoolers get involved in a rich array of co-curricular activities outside the classroom, exploring their talents, passions, and interests. These activities are an integral part of student life, reflective of the school's commitment to intellectual growth as well as to the development of each individual's creative, social and emotional well-being.
Club offerings may change from year to year, depending on the interest of the student body. Different clubs meet each day during recess so that students can join a number of clubs while still being involved in after-school sports teams and theater productions. Clubs in the last few years have included: Book Club, Chess, Comic League, Diversity Club, Film Club, Macrame, Music Club, Students of Color Support (SOCS), Student Government, Newspaper, Sustainability Club, Yearbook, and Dungeons & Dragons.
Calhoun's Middle School students are exposed to the wealth of New York City museums, as well as numerous other cultural and educational resources. In addition, students in every Middle School grade participate in at least one overnight trip each year.
