Founded in 1937, Middlesex Middle School serves public school students grades 6-8 in Darien. Each year, students are organized into groups called teams, consisting of approximately 80-90 students. Students only take classes with their peers who are on the same team as them, and within each team there are different teachers for each core subject. In addition to core classes, students take music, art, physical education, computer, technology education and family studies throughout their middle school education. Dr. Debi Boccanfuso is the principal.
