Parent: Trinity has been an amazing experience for my daughter. She came in 9th grade from an all girls school (Brearley) and my daughter had the fortune of choosing between Trinity, Dalton, Horace Mann and Exeter. We were worried about the academic intensity but my daughter was well-prepared by her time at Brearley and thrived in an environment where students are constantly challenged and pushed to do their very best. She loves her classmates, and finds the school much more diverse than Brearley. Overall a great experience so far!

2 Best Private K-12 Schools in America
Alum: Attending St. Mark's was the best decision I have ever made. The school made me grow academically, but even more as a young man. With bountiful leadership opportunities through the Community Service Board and Telos, I was able to take full advantage of serving those around me. In addition, the Wilderness Program taught me character and really helped bound my class. The teachers at St. Mark's are first-rate, and they are always available for office hours and really want to get to know the student. The student body is full of compassionate and caring young men, and anyone can fit in. Without my St. Mark's education, I would not be the man I am today.

My brother goes to Trinity, and we can both agree Collegiate is a way more superior institution. Collegiate is forward-looking, fresh, vigorous, immeasurably fun, and overall great school

The Harker School
Private School
San Jose, CA
PK, K-12

4 Best Private K-12 Schools in America
Alum: I graduated from Harker having gone here since kindergarten. Harker is a truly unique place because of its combination of school culture, top-level academics, and burgeoning athletics. While there is a sense of competitiveness and stress (mostly seen in the high school level), the teachers and students that go to this school are all wonderful, kind people who come from a wide range of socioeconomic and cultural backgrounds. As a student, you'll find so many options to choose from here: the multitude of clubs and student-run organizations, nationally-ranked speech/debate programs, business/entrepreneurship programs, sports (both varsity and JV), and musical (both singing and instrumental) departments. And I haven't even mentioned the academics, which is the biggest reason for Harker's success over the years. I've had the best experience here for over a decade, and I am ready to go to college safe in the knowledge that I've been very well prepared to make my mark on the real world.

Horace Mann School

5 Best Private K-12 Schools in America
Senior: Going to Horace Mann challenged me both mentally and emotionally. I had never experienced a curriculum as stimulating prior to me going to Horace Mann. Their facilities, resources and academic opportunities have allowed me to be both socially and politically conscious of the environment around me. The students that you meet strive for nothing less than perfection. But I will admit that this yearning for perfection can be emotionally and mentally taxing on students. It can be hard to be in a school where almost everyone is a perfectionist and where the school grooms you for college from the very beginning. It can be overwhelming and tiring to have such expectations placed on you. But without the pressure put on by teachers and administration, I would not be as ready for college as I am now. Horace Mann guided me every step of the way through the college process and helped tremendously with anything I needed financially. The challenge is worth it, and so is attending Horace Mann.

Junior: There are so many opportunities at the school, that you can honestly do anything you want to pursue your passion. The teachers are always there for you, and are there to help you improve all the time. The academics are strong, and it's honestly so manageable.

Poly does truly have a really competitive environment. Because the school is so small, you get to know everyone, and you realize the amount of competition that exists within every grade. Sometimes, you really just feel stupid in a class (I know I have). But I love this school so so much, and I have honestly met some of the best people in the whole world. Though it is competitive, everyone is welcoming, and once you feel a part of the Poly community, you feel like you can conquer the world. I am so happy I chose this school and don't regret my decision to come. GO POLY!

7 Best Private K-12 Schools in America
Senior: Sidwell Friends School has been an amazing place to foster my intellectual growth. Sidwell is a Quaker school and Quaker values (especially community and integrity) are very present within the school environment. Students are very involved in the school community and participate in various activities including club, plays, athletics, orchestra, chorus, and jazz. Teachers are always available to help and foster students that are sensible, compassionate and bright. At Sidwell I have been surrounded by students that genuinely care about whats going on the world around them, want to change the world, and are using their education to do so.

8 Best Private K-12 Schools in America
Parent: Dalton offers an incredibly challenging academic environment for it’s students. As a School with a progressive philosophy expect students to be charged with managing there studies and responsibilities on there own from a very young age. Music and arts a a focus but sports are somewhat of an afterthought. A quick poll of parents will have you believe that every child is easily getting A’s. Don’t believe it. The use of tutors is pervasive. The amount of homework is staggering. I have a student there and the teachers share test and project grade averages. Trust me when I say all kids are not getting A’s. For those kids who can cope with the homework and absorb the material Dalton will turn them into super students. Word on the street is that after Dalton, college is a breeze for these kids. Then again all those kids may have been the ones that easily got A’s :-)

Milton Academy

9 Best Private K-12 Schools in America
Senior: Milton Academy is one of the best things in my life, but also the most stressful. The opportunities at Milton are endless and I feel incredibly privileged to have teachers that care about my well being, activities and clubs, a beautiful campus, and a seemingly endless supply of resources (such as art supplies, computers labs, food).
Our food selection is incredible with a food for every person in any mood. The staff is always kind which just adds to the joy of lunchtime.
While there are teachers I have heard about that are hard to work with or learn from(which happens anywhere), I have been very lucky to only have dealt with one teacher I didn't like (out of more than 25). I appreciate the skill level that the teachers have and the personal relationship that students can build with them throughout the year.
I think that the faculty is very fair and thorough when dealing with disciplinary issues and I completely agree with the standards of respect and honesty that we are held up to.

Alum: Westminster gave me the challenges, opportunities and support to become the person I am today. I'm getting my degree at my university but I got my education at Westminster. Now having the chance to compare my high school experience to that of my friends in college it is even more clear that Westminster is an incredibly special place. I have always loved to learn and I think at any other school that love might have diminished instead of being nurtured. I will always treasure my time there!

11 Best Private K-12 Schools in America
Senior: I've absolutely loved my experience at Head-Royce. There are a few things that I'd want to change. As a minority at a predominantly white school, I can often feel alienated and without a voice. Minority students either abandon their culture completely or are extremely cultural, both of these being ways of survival in an environment thta does not look like them. There really is not a middle ground. but it is relatively easy to find small group of close friends and teacher who will support you. The academics are absolutely amazing, and the college counseling team is stellar. You're sure to attend an amazing university, if you attend Head-Royce.

Every family who comes here feels very welcome in the Brearley community. The school prepares students exceptionally well for college. The school is one of the safest out there, excellent security. There are many clubs and activities for the students to get involved in. Academics are top notch and the girls who come here have fun while learning!

Junior: The teachers and administration really do care about your well-being. Sometimes that manifests itself as tough love but you always come out a better person after. They also want to help you in any way they can. Personally, my advisor has worked with me to get me in the classes I want and encouraged me to take risks with classes I hadn't thought about before. The college counseling is top-notch. The campus itself is extremely nice, but the girls' bathrooms leave something to be desired. The student body is incredibly diverse; I have close friends of all colors, from places like Russia, Vietnam, China, Korea, etc. The diversity of perspective is the diversity of the campus ten-fold. The people I have encountered here are some of the nicest, most thoughtful people I have ever met. They are outgoing, accepting, everything you could want from classmates. Overall, my experience here has been amazing, and I highly recommend this school to others.

14 Best Private K-12 Schools in America
Parent: Plus:
Extreme college prep (getting tired of other parents telling me how their child thinks MIT was easy after Lab), theme of asking "why" in addition to "what" in every pursuit, general consistency in teaching excellence, well-organized academic programs, culture of excellence among students, nifty vibe on UChicago campus, good facilities, no-cut athletic programs

Minus:
This school is very religious (religion of liberalism, social justice, and multiculturalism--which are all laudable, but they lay it on very thick), too many helicopter parents, too much homework, superficial diversity (does not represent the actual SouthSide--seems like most of the black/hispanic kids have rich or famous parents. In general, minimal socioeconomic diversity), virtually no school spirt in a traditional sense (sports, school sweatshirts, dances).

Senior: The science and math classes were amazing, and teachers were great! We're working on our Computer Science program though. In terms of diversity, it is quite white despite the school's efforts.

The administration is probably the worst thing about the school. It's very complacent and when it comes to disciplining us, they don't do a very good job.

Besides that, GDS is a wonderful, quirky place where you can feel comfortable, relaxed and still be challenged and engaged in class.

Junior: I have been attending Pine Crest School since I was 4 years old. The educational experience received at Pine Crest is extraordinary. There is an extensive list of extracurriculars for students to get involved with. Although challenging, teachers are always helping students with time management. The school provides students with a College Admissions Office that helps students from choosing their classes freshman year through the college application process. The athletic facilities are top of the line, but the teams aren't all fantastic. The reason for this is because the culture at Pine Crest strongly promotes an academics-first mindset. Overall, I have had a great experience at Pine Crest and would definitely recommend it to anyone.

Senior: Though Chapin is a diverse and open community and has progressed to take more active stands social justice issues over the years, there is always room to improve. I think we need to focus more on action in our community. I have been thinking about this for some time, and I think Chapin should hold its own high-school wide diversity conference during a town hall meeting slot in which we would simulate some of the same discussions and activities from the Student Diversity Leadership Conference for all of us to experience. I think that, if that meeting were successful, it would be eye-opening to then include other inter-school students in this discussion, and host our own Diversity day. Also, as an individual I will of course continue to try to make our community as safe a space as possible both by voicing my own experiences and also, as an ally to other marginalized groups, by giving space for others to use their own voices.

Middle School Student: Academics are very good. Diversity could be improved. Teachers are wonderful. We have plenty of security guards to keep us safe. The school works very hard to create a open and welcoming environment. Sports are good but not great, the coaches are not very educated in the sports they coach. The food selection is very wide and it is good quality and healthy, however it is VERY overpriced (chicken and pasta was $9.25) Facilities could use improvement. In old buildings heat and air conditioning is poor and bathrooms are disgusting.

Freshman: Honestly, this school is amazing. I have been here since kindergarten and am now a freshman. There are small things that could be different. I feel Pingry could work on "sheltering" less. I feel like I have not experienced anything "real" because of Pingry. If there's anything would probably be from my personal life, not because Pingry has exposed me to it. This has had such a big impact in my life because I can tell when I am around my friends they act differently towards me than to our other friends. Like sharing something funny on their phones and saying that I wouldn't get it. I love this school a lot, but I feel like I am this perfect little private school girl who has no clue what happens around in other aspects of life. This school does a great job of getting us ready for college in terms of academics, but in terms of social comfort zones, not so much. At my school there's friends groups and cliques.Other people here don't try to be a part of other groups, which to be a problem

Junior: There is no other school like Hockaday. Our teachers challenge us with new topics and ideas in our studies, but also come out to support us in sports events and fine arts showcases. The friends that I have made at Hockaday compare to no where else. I always know that I can trust them, and, most importantly, make me laugh. Lastly, I know that after graduating that I will feel prepared to take on the world with both its exciting adventures and challenges with confidence after the Hockaday education I have received on lessons for in and outside of the classroom. Hockaday can at times be challenging but cultivates an inclusive, supportive, and positive community that I am proud to be a part of.

Alum: The sense of community at this school is amazing and something I definitely miss having graduated. My decision to attend this high school was by far the best decision I've made and prepared me so well for college. Couldn't have possibly wished for a better high school and definitely can't imagine my life without Greenhill in it! Athletics played a huge role in my time at Greenhill and I really don't understand why sports is rated so poorly on here. Football isn't the only sport at the school - they did struggle for a while but they're a great team now anyways. But regardless, Greenhill definitely has good sports teams and athletes. By far one of the strongest SPC schools in many different sports. In addition, the bonds of teams and the tight-knight relationships/friendships formed through athletic teams at Greenhill is priceless.

Hackley School

Tarrytown, NY

23 Best Private K-12 Schools in America
Sophomore: As a sophomore currently in Hackley, I can only highly recommend the school. The academic program is one of the most rigorous out there even if it isn't noticeable in the school. Various AP classes and advanced electives are the common practice beginning sophomore year and beyond and some freshmen may even take some as well.

The English Department is considered the bane of most students' existence and goes into such analytical depth that it rivals any AP English course out there.

Transitioning from a public school to this could be difficult, especially if it's into the Upper School. The rigorous curriculum will challenge you, and lower grades than usual will appear. Our strongest science and math students who take on AP Physics C and Multivariable Calculus in senior year are subject to the two most difficult classes in the school, classes that can give test grades as low as 40 on a regular basis. It's worth it though, the experience is unforgettable.

Senior: St. John's faculty are super engaged, hands on, and truly passionate about what they are teaching. They seem to genuinely care about every student. They are available to simply talk to whether you need help to understand a concept or are having a bad day. Similarly, the students are almost all just as engaged and interested in what they are learning. I do have some comments/complaints. The school and the students at the school have A LOT of money that is used for the most boujee things imaginable. 10 thousand dollars on cookie cake? Yes. Getting too lazy to water the grass so they spray paint the lawn green? Of course! Building a new baseball field, realizing it faces the wrong way, and then rebuilding it again to make it face the other way? Yep. The school is constantly under construction building many often unnecessary buildings and fields.

No busy work for homework, all homework helps you grasp the material. Also the teachers are amazing and students are amazing. We go on school trips, starting at Peru, Costa Rica then trips in America. And the first year they want you to get a grasp of the content so you don't have grades that go in the college transcript.
