Commonwealth School Reviews

Commonwealth School provides a fantastic education which challenges students to develop deep academic understanding. This is because teachers at Commonwealth School are very qualified and are experienced in making challenging material understandable and interesting to all students. Even though the tests are extremely difficult and teachers grade harshly, students are able to gauge their understanding well. The only downside to this is that students have very low grades in terms of college admissions.
Beyond academics, there are a multitude of fantastic clubs and teams. Ranging from anime club to chess team, students can find a variety of clubs at Commonwealth. While options are limited since the student body is under 150 people, the clubs are run with good leadership and inclusive principles. The best part of Commonwealth is the community. Everyone is there with a passion towards and learning and a goal to make Commonwealth a better place for everyone.

Commonwealth is an extremely rigorous school that is very good at facilitating learning and helping prepare for college. The teachers are incredible, and are all there because they are passionate about the topics they teach. As a school, it has improved greatly at providing support for its students. I hope to see this improve further. Its extreme rigor can be quite challenging, though the school does offer good academic support if you reach out for them. Because of its small size, it has a strong community of students and faculty, though the small size can also feel claustrophobic. The facilities are quite limited, but the open campus and convenient location allows access to all of Boston's facilities, such as the Boston Public Library which is within walking distance, and sports facilities such as BU's soccer fields.
Commonwealth provided me with an extraordinary education. My classes at Commonwealth were more rigorous than at my Ivy League undergraduate and graduate schools (Princeton and Yale). It is a suprisingly well-rounded school with a serious science curriculum, strong English classes, and nearly-college level History classes. Juniors and seniors can take a variety of electives such as Art History or Constitutional Law. The small size of the school means that there is a strong feeling of community. Classes are never bigger than 12 students. The general environment is a very warm, inclusive one, although the school does lean heavily liberal.
