Commonwealth School

Commonwealth School, founded in 1957 by renowned educator Charles Merrill, is a unique independent day school in Boston's Back Bay, offering a rigorous humanities-centred college-preparatory education for grades 9–12. With only 150 students, Commonwealth is one of Boston's smallest independent schools, creating an intimate intellectual community where students are known and challenged individually. Accredited by NEASC, the school is celebrated for its exceptional focus on writing, literature, mathematics, and the arts, with a low student-to-teacher ratio of approximately 5:1. Commonwealth's alumni include Pulitzer Prize winners, MacArthur Fellows, and graduates of every major US research university. The school does not offer athletics or extensive extracurricular programming; instead, students are expected to pursue these interests in Boston's vibrant city life. Its Back Bay location, steps from the Boston Public Library and the Fenway cultural corridor, provides a uniquely urban educational environment.
