    Commonwealth's faculty deliver a level of academic rigor that I've been unable to find at other schools. Just as amazing to me is the amount of nurturing and support the school is able to provide to students in attaining their full potential. Thanks to Commonwealth's small size, students are able to meet one on one with their advisors on a weekly basis. A good number of the faculty have university teaching experience, yet it's abundantly clear from the individual attention they give students both in and out of the classroom that they're at Commonwealth because they love teaching and working with teenagers. Another key ingredient in the quality of this school are the students it attracts: bright, curious, unpretentious, and not cliquish. My daughter, who tends toward quiet and reserved, has been at the school as a ninth grader for under a month, but has already made close friends. We're extremely fortunate to have found this school; I can't recommend it enough!

    Commonwealth's strengths are its strong community and excellent academics. The teachers challenge students to think, create, and question, which results in a highly engaged and intellectually stimulated student body. All of the teachers are terrific, and you can see how passionate they are about their subjects and students. My child has gained confidence and learned important critical thinking skills while at Commonwealth, which will well-prepare him for college and beyond. The community is tight-knit, but welcoming, inclusive and diverse, which allows for a range of perspectives both in the classroom and without. The Back Bay location also expands the school's campus to include all of Boston, and students are able to take full advantage of all the resources the city has to offer.
    My experience at Commonwealth has been spectacular. The academics are challenging and taught by teachers who are passionate about their subjects and see teaching as more than just a job — they are actually excited to be in the classroom, which makes the experience that much better for the students. The school is very small, which can be slightly constricting for some people, but also means that everyone knows everyone, which makes the school a very close and welcoming place. I, a female student interested in STEM, have never experienced any gender-based discrimination at the school, and every single one of my advanced math and science classes has been approximately gender-balanced (50/50 or 60/40). Commonwealth has given me a place to grow academically and socially, where caring about school is not judged and the students and teachers want to be there. I would absolutely recommend the school to any student passionate about learning and willing to work hard.
