Parent: 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.... Read 36 reviews

Senior: It is hard to put into words the incredibly positive impact that this school has had on my life. Coming in as an awkward freshman, I was greeted by a welcoming community of intelligent, funny, and hard-working students and teachers that have supported me since day one. Through the most amazing sports teams, clubs, organizations, and even just academic classes, I have made memories and formed relationships (with students and teachers alike) that will last me a lifetime. Now as a senior in my fourth year at the school, I feel confident in myself as a learner, friend, teammate, leader, and person, and so much of this is thanks to Nobles. Starting with assembly in the morning, and ending with "Dogs on three, one, two, three, DOGS!" at the end of practice in the afternoon, the constant infectious energy makes it a joy for me to go to school each day. I will miss this place dearly and plan to stay connected long after I graduate.... Read 55 reviews

Senior: Milton Academy students leverage their top-tier academics to achieve their goals. Whether that be in academics, athletics, the arts, or in social justice, everything these students do is done at the highest caliber. We love to learn and bond through knowledge! I would describe its community as full of social nerds. Milton has provided me with endless opportunities and has expanded my network immensely. Thank you for a wonderful three years so far, Milton. While I’ll be moving onto a new chapter in the next couple years, I know I will always have Milton’s support.... Read 148 reviews

Parent: BUA provides a unique opportunity for students to have the best of both worlds: a small dynamic curious community couched inside of a large university with endless opportunities. The classes at BUA are taught by high quality professors and teachers who are dedicated to their subject areas and to helping students. Expectations are high and for the student who seeks challenges while learning to navigate student life in the city, BUA is an enriching opportunity. Students learn to navigate taking college classes while at BUA which is a huge advantage because course offerings at the university level are diverse. Students become independent learners as they advocate for themselves in the university environment. This school has a unique culture attracting students and families who have inherent interests in learning, an unparalleled curiosity and kindness. My daughter who is a senior now has loved every year of her time at BUA and is over prepared for her next steps at college.... Read 66 reviews

The school also offers a robust extracurricular program, including sports, clubs, and community service opportunities, which further enrich the student experience. What sets BB&N apart, however, is the sense of community and inclusivity that permeates the school. Students come from diverse backgrounds, and the school actively works to foster an environment of acceptance and respect. The faculty and staff are incredibly supportive and engaged, and parents are encouraged to be active participants in their child's education. Overall, Buckingham Browne & Nichols School is an outstanding institution that provides an exceptional educational experience.

There are plenty of kind and friendly fellow students to bond with in classes, sports, performing arts, clubs, and other activities.

Alum: This school has had massive influence on my mind and spirit since matriculating in the JFK era. Can't really speak for current performance of school leadership and its culture, but lived it during an especially troubled and troubling time. Sorry to say it, though the obsession with Harvard, etc. detracted from the healthy experience that we needed so badly, but which was not available to many, despite the boosters who would cling to the idea that they had not been damaged nor damaged others. Bullying was the norm in our time, and one learned how to "blend in" so as not to receive the horrific public shaming that "gay" or otherwise non-standard boys would get. Not the best preparation for an accepting or humanistic mind set for life, one asserts. "IQ" learning may have been at the highest level than any school in the country if not the world, in one's time there. The Howard Gardner "Multiple Intelligences" model was unknown at that time and so the three R's plus sports dominated.... Read 48 reviews

Sophomore: There are several reasons why my high school is so dear to my heart and I really adore it. I have had the opportunity to explore several facets of academic life as a rising sophomore, which has made my journey extremely exciting and gratifying. First off, my high school offers a tremendous variety of extracurricular activities. Being a member of the soccer team has given me the opportunity to hone my talents, promote collaboration, and create enduring connections with my teammates. To sum up, I want to say how appreciative I am of my high school and the chances it provides. My high school experience has been really gratifying because of the variety of extracurricular activities, the academics that are in line with my interests, and the supportive environment. As a rising sophomore, I am eager to continue my path because I know that my school will continue to encourage my development, push me, and provide the groundwork for a prosperous future....

Parent: We have been very pleased with our Rivers experience. In addition to offering excellent academics and extracurricular opportunities, the school is committed to student wellness. There are two full-time counselors available, and the student-faculty advisor system provides an additional layer of support. We found the school to be extremely supportive of our child when they experienced anxiety during the pandemic. The school also spends a great deal of time talking individually to each student and their parents about course selection to ensure that each student is appropriately challenged. Overall, we are very grateful that we chose Rivers!... Read 44 reviews

Parent: Our son started as a 9th grader in the fall of 2020. The school has exceeded our very high expectations. Even with the ongoing pandemic, the school has managed to provide an academically rigorous and caring/supportive community. The teachers are extraordinary. They know our son very well and truly care about his academic AND personal and spiritual development. His academic transition from public school has been seamless. We are confident the education he is receiving will prepare him very well for college. In this uncertain time with so much angst in society, I can not think of a better community for our son to be part of. On a daily basis the faculty and administration communicate their time tested wisdom that allows him to help filter out the current angst and noise that surrounds us all. We are extremely grateful we can call St. Sebastian's home. Sending our son is truly the best academic decision we have ever made.... Read 50 reviews

Parent: We have experienced both public and private high schools and in the end, it’s what the student makes of the available opportunities. We find Dana Hall to be an excellent school with caring and responsive staff. Students have weekly one on one meetings with their advisor as well as daily group meetings. The environment promotes girls to take on leadership roles as well as fostering a spirit of sisterhood through their many school traditions. We were initially hesitant about sending our kid to an all girls school but so far, she academically amply challenged and is very happy where she is.... Read 73 reviews

Test taking and paper writing are more limited, so college preparation in those areas is difficult. The student body is small so a little cliquey.

Parent: Our children moved from a local State school to BISB three years ago. From day one the school has provided a first class academic and social education, helping children become well rounded members of the community. The curriculum is varied, thought-provoking, interesting, and challenges and encourages the children to be creative and ambitious. The teaching staff are very attentive to each individual child’s learning capabilities and needs, and the small class sizes are a definite advantage. As an international family we are excited that our children will have the opportunity of doing the IB Diploma, a highly regarded and recognized qualification that provides children with a wonderful springboard to move into higher education not only in the US, but worldwide. Overall as parents we are thoroughly impressed with the school as a whole, but more importantly our children are engaged and interested in their education and really enjoy attending school each day. We highly recommend BISB.... Read 102 reviews

Gann cares about its community, and wants everyone to feel safe and welcome. Gann works to create new and innovative ways to educate students, as well as help create/nurture future leaders.

Parent: An outstanding, thoughtful, knowledgeable, and passionate team delivering world class education! ISB offers a strong curriculum, offers best practices from across the world, and gives our children the option of a global education. We have been very impressed in all aspects of our experience thus far, from management to operations, and most importantly the way everyone interacts with the children. It is a beautiful experience to watch a child get excited about learning a new language from a community they enjoy being a part of. The safety and wellbeing of our children and teachers is very apparent by their detailed and well thought out protocol surrounding the pandemic. Their consistent, supportive and transparent approach with families, along with open dialogue is much appreciated.... Read 81 reviews

Sophomore: I have gone to school here since sixth grade, and I am about to enter my junior year. The dedication NCDS has put into my education is truly astounding, and continues to leave me in awe with every new year. I love everything about it, from the various committees/clubs you can partake in, competitive and fun sports teams, Sacred Heart traditions like conge, and the supportive TAG program for middle schoolers and the advisors program for upper schoolers. Between my advisor, my teachers and my coaches, I know that if a problem arises that I need help solving or just need to talk out, I have an abundance of options for people to turn to. Classes are also challenging, but with the support every student gets from their teacher, they are manageable. In addition to other committees, I also enjoy the computer science classes and the Independent Research Program, which allows girls to expand their horizons in STEM.... Read 59 reviews

Parent: When looking for schools for my son, I wanted the strong academics, but I also wanted an environment that fostered independent thinking and discovery; an increasingly difficult combination to find given the climate of education and expectation these days. However, Beaver delivered it all. The core skills being taught are the same as what other schools are teaching, but Beaver does it in a way that draws the students in to ask questions, test their own ideas (knowing that it is ok, and expected, for some ideas to flop), and explore topics as they apply to real life. AP classes are not offered and that is a huge pro, not a con. By taking them out of the mix, students have space in their schedules to try classes that pique their interests...Neuroscience and Theories of Justice to name a couple. The list of colleges into which graduates matriculate year after year is a testament to the strong education students are getting and how it is perceived in the broader academic world....

In addition to academics, teachers mentor students and support each of them along their unique journey at Montrose.

They feel loved and connected in addition to loving the curriculum and coming home every day to tell us what they are learning. They are engaged and excited about learning! The schools in all divisions are very strong at individualizing instruction and caring for the whole child-emotionally, socially and academically.

Parent: The admistration is highly productive. They did not lose a day of teaching in the pendemic. They has no expereince for the online teaching before the covid hited us. Right after the spring break, online lessons were started as a half day program on Monday. On Wednesday, they switched to a whole day class to fully engage students. They never missed the summer camp and even open the campus much earlier than most other schools still did not know how to open their campus. It truely respect people's choice & rights. Never force anyone to be vacinnated. They teach kids critical thinking by allow them to listen to all perspectives instead of teaching kids to one direction which would altimatly destoy the country. Teachers are really caring about kids and would approach parents regarding how to help the kids become better. Not the fake love elsewhere. Great school with true loves, caring and common sense.

Alum: I loved my time at Maimonides! The school ensures that students leave with a great education in both Judaic and Secular studies. The classes are taught by wonderful, devoted teachers who build strong relationships with the students. The personal interactions are a unique feature of this school that can make any student feel comfortable. Maimonides has built a culture where the students support each other while also challenging each other to achieve the most that they can. Being a Jewish School, Judaism is sewn into the fabric of the school with a foundation built upon Jewish values, Jewish classes throughout the day, and opportunities to learn and develop Jewish identities. Students here, are known for their advanced Talmudic skills and Derech Eretz (respectful behavior). Maimonides manages to perfectly balance the seriousness of an academically-focused school, with a supportive culture that comes with being a smaller school.... Read 38 reviews
