School Reviews

5  
Commonwealth students receive a distinguished education in a small community, which allows faculty and students to know each other and work closely together. It is akin to an idea lab bringing bright people together from different areas. The kids work hard and graduate, having had the equivalent of colleges` freshman/sophomore education. The campus is not extensive compared to suburban schools, but that does not prevent the school from offering sports, performing arts and other electives. Most students commute, which develops independence and urban savvy, and the school does a good job of introducing students to some cultural and geographical history of the city of Boston. Parents are also engaged through social events and volunteer opportunities. It is a special place.
