    The best of Commonwealth is the faculty and staffs! They are very caring and dedicated to help each student to improve and grow. My son started quite a few weeks late on the first year. I was very much impressed with how the school planned for my son’s curriculum. They truly encourage the students to take off as high as they can. The teachers are so helpful that my son was able to quickly catch up everything.

    The low teacher-student ratio makes it easy to schedule a meeting with any teacher to discuss any issues and concerns. The administration is very supportive who had worked very hard to create my son’s schedule due to course change this fall, while they were so busy with preparing the school for the hybrid learning mode. They amazingly turned the in-person learning to fully remote during the spring break.

    Commonwealth school offers authentic education. You'll see how fantastic students development themselves to be intellectual, responsible and sensible young people.

    My daughter is an alum of the school. Her experience at Commonwealth was superb!
    Caring faculty, collaborative environment, first rate academics and importantly a culture that teaches the students to take academic risk and to push way beyond the memorization/regurgitation of many high school experiences. My daughter grew tremendously as a person as she was pushed to be the best she could be but in a supportive, encouraging way. She was VERY well prepared for a rigorous college curriculum and is light years ahead of many of her fellow classmates in her ability/poise to tackle hard things in college. Not the school for everyone but for students looking for the challenge without the cut throat atmosphere, Commonwealth is a gem!
    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!
