Commonwealth is a college preparatory school with a rigorous but achievable set of academic standards. Our core subjects parallel those offered at other independent schools as well as public schools. The difference is the way we teach, and the specific accommodations or compensatory strategies that students learn to use in order to master their assignments. Our faculty is comprised of teachers trained and experienced in their subject area, who complete ongoing, structured training in developing and using compensatory strategies in the classroom. Beginning in middle school, faculty advisors meet with their students on a daily basis to build study and organizational skills, teamwork, and to review biweekly reports.

Constantly evolving, our curriculum is frequently enhanced to reflect the special talents of individual students. If a student needs more advanced challenges, we will develop coursework or a new class to keep him or her progressively engaged. We offer several honors courses, such as Linear Algebra, Honors Physics and Honors British Literature. In the middle school, we continue to develop cross-curricular activities to enhance the relevance of classroom learning and relate it to the real world.

In addition to core academic subjects, students participate in physical education and a wide variety of electives through which they can sample new activities and explore their interests in more depth. Clubs meet weekly, providing another avenue for students to pursue extracurricular activities, as well as additional opportunities for social interaction.

We highly value success in all student endeavors – academic, artistic and athletic – and celebrate students' talents throughout the year. Honor roll students are formally recognized with certificates of achievement; parents attend theatrical performances staged by middle and high schoolers, as well as the Annual Middle School Science Fair.  We showcase the talents of our young artists and publish an annual collection of students’ poetry at the Annual Art & Poetry Show. And, both peers and parents enthusiastically support our basketball team.
