Boston and the greater New England area are known for premier colleges and universities. This pattern transfers down to the secondary schools in the area, which are equally competitive and rigorous.
Housed in a brownstone building, Commonwealth School is one of the most respected schools in Boston. This private, coeducational school is small but mighty, with a current enrollment of about 150 students in ninth through 12th grade. The coursework is rigorous and creative, with smaller classroom sizes allowing individualized academic attention. It enables students to delve deeper into subjects of interest, such as social sciences, the arts, languages or history, where they can study everything from photography to Mandarin.
Students who decide to take on a second language can expand their knowledge and even travel to France, Spain or Italy through Commonwealth’s study abroad program.
The school also provides clubs, sports and a literary magazine that students can join. In addition to extracurriculars, Commonwealth hosts special guest speakers on most Thursdays ranging from politicians and alums to Grammy award winners and jewelry designers.
