  1. University of Chicago Laboratory Schools

    • Private School
    • Chicago, IL
    • PK, K-12
    • 106
    1 Best Private K-12 Schools in Illinois

    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).

    2 Best Private K-12 Schools in Illinois

    Parent: The school provides a rigorous, well-rounded education. Class sizes are small in the elementary school years so children receive a lot of individualized attention. The science and arts program are quite strong. The only areas of improvement are diversity (less diverse than private schools in Chicago due to location) and breadth of extracurriculars.

    3 Best Private K-12 Schools in Illinois

    Freshman: I have been here for a while and the school is very intriguing. Latin's academics are great, and have helped me in many ways to learn things that I have not been able to understand in previous schools. My only problem is that the social scene is a little bit cliquey and students (including myself occasionally) feel obligated to be sad about being left out. This includes parties of about twenty to thirty kids every weekend that is streamed on social media so others can see. Some students also participate in alcohol and e-cigarette behavior, although that is a minority, it usually is the kids at the parties. But otherwise, I love Latin and I am proud to be a Roman!

    Works Here: I have been working at the Kirov Academy since 2017, and have found the staff & students friendly. The students are very talented, even performing for a week at the Kennedy Center in conjunction with a major company! The teaching staff, both academic and artistic are professional, run an excellent program that prepares the students well for both companies and university placement.

    • Private School
    • Chicago, IL
    • PK, K-12
    • 47
    4 Best Private K-12 Schools in Illinois

    Senior: I have had an awesome experience at Francis W Parker. Teachers at Parker are creative (and free to make their own curricula because of Parker's progressive philosophy) and teach students mind-blowing ideas, along with critical thinking skills.
    However, the unavoidable smallness of each class makes some students too comfortable with one another - everyone knows everything about everyone. Additionally, many reputations stick from middle school.
    Yet the education, especially in history and English classes, is great. Parker has, however, been trying to improve their STEM classes - they finally introduced higher-level math courses into middle school curricula, and now high schoolers must take computer programming/coding for at least one year.
    Recently, because the administration in the high school has been changing for around 5 years now, some students feel that they have less influence in school processes than they used to.
    Overall, though, definitely come to Parker!

    5 Best Private K-12 Schools in Illinois

    Parent: Best parenting decision ever for our seven-year old. Here is why:

    The faculty: The teachers are incredible and genuinely care for each single child. Great teacher to student ratio (1/14) and excellent leadership.

    The diversity: 48% students are non-Caucasian. The school models a sense of social responsibility by taking part into community-oriented projects.

    Differentiation: The pedagogical approach is all about differentiation. In the lower school, the kids break up into need-based groups across two grades (first and second, third and fourth) for reading and math, with support from a gifted coordinator. Academics are very strong.

    Ethics: The lower school participates in a great program that emphasize “seven habits” including collaboration, respect for others, self-motivation, organization, etc. The teachers design imaginative activities prompting the kids to apply those habits in real life.

    The space: The facilities are bright, clean, and colorful.

    WE LOVE ROYCEMORE!

    6 Best Private K-12 Schools in Illinois

    Alum: Morgan Park Academy cares about it's students! You are able to get one on one assistance with your teachers if you need help. I attended this school from pre-school-3 to 12th grade, needless to say I was a super lifer at that school! Although the class size was really small (<30 graduating class) I really think that helped me learn to understand others and navigate through conflict. MPA prepared me for my college career through academics and the general care it has for students. If you (or someone you know) is considering MPA, do it, looking back I am grateful for the lessons I have learned (academically and socially) as a result of being a student at MPA.

    8 Best Private K-12 Schools in Illinois

    Alum: I attended the Lycée from pre-K through twelfth grade. Now, with a year of college under my belt, I am overall very grateful for my time there. The teachers were like family, as were your peers, since it was a small and tight-knit community. Be assured, it's a very heavy and at time grueling workload, especially for an American student who didn't speak French at home. But the feeling at graduation, exams done, celebrating with your best friends, teachers, mentors, and family, is irreplaceable!

    Parent: An excellent education that is truly Christ-centered and tenderly nurturing kids and their heart for the Lord. Students are challenged academically (as seen in their awards & scores), but flourishing because they are supported spiritually and emotionally. Loving and exceptional teachers are mentors who partner with parents. Our 3 kids are thriving here! High school: AP courses available starting in freshman year, high scores, high % of National & Presidential Honors students. Many opportunities for service and leadership, including Winterim and mission trips. Graduates are attending excellent schools, prepared for college, life and beyond.

    Alum: Good overall. Small class sizes ranging from 7-30 students, and the faculty was passionate about teaching. As always, some days were better than others since being in a small community has its pros and cons (e.g. Pro: you know everyone, Con: you know everyone).

    Senior: The education here is amazing! They really prepare you for college with implementing a lot of critical thinking in the course as well as a lot of essay writing. I also think that the teachers are the USP for the school. The teachers are very hands on and because they are very young it creates and a better student teacher relationship. The teachers genuinely care about our education and do everything possible to provide us with the best experience and education possible. Although, the social aspect of the school is quite poor but I think now that the school is growing the social aspect will be better, especially because the school is now trying to implement a more high school feel for the students. Overall I think British school is one of the best schools in Chicago!

    13 Best Private K-12 Schools in Illinois

    Senior: Chicago Waldorf High School has been the best choice I could have ever made. They Do not “teach to the test”. The students are met with age appropriate challenges that allow them to develop their own critical thinking skills. The friends I have made will be with me for life. I went on exchange to Colombia for 3 months and hosted the student I lived with here for 3 months. There is a constant stream of exchange students from all over the world coming in for a semester that you get to know. When you have experienced being an exchange student yourself, you know what it’s like to be that kid coming in with all of your insecurities about speaking another language and being so far away from your home and your family, so you are likely to lend a hand, be friendly and get to know the exchange students. The small class size allows for service learning experiences that you would not get anywhere else. My college application process went smoothly and I got accepted to my first choice!

    Senior: Islamic Foundation instills good moral character, and has outstanding academic standards. The small school and close community accepts all and everyone os treated like family. This is almost always a good thing, one of the only drawbacks would be the unprofessionalism you can see on occasion amongst faculty; whether that be through petty, immature, or unreasonable uses of authority.

    15 Best Private K-12 Schools in Illinois

    Senior: The one thing I love the most about CPSA is how much they care. From top to bottom, every staff member will go out of their way to make sure you're ok, to help you with schoolwork, or even just to have a conversation as a friend. This school took me in and made me feel like I was worth something, like I can actually accomplish great things in life. Yes, it is a private school so maybe we don't have the best infrastructure or the biggest budget, but the environment that you're nurtured in makes you forget about the small inconveniences and allows you to focus on bigger and better things in life.

    Senior: Real authentic Christian education that values community. I have been going to Timothy Christian for the past five years. It is such a wonderful community of people. I genuinely feel excited to go to school every day! There are so many opportunities to participate in sports, academic extra curricular, even e-sports! (And we take home lots of trophies in everything we do). My favorite thing about Timothy Christian is how much the teachers invest into their students-time, energy, and love. We have weekly chapels which prove that this is a true Christian environment that practices what they preach.

    Senior: Hinsdale Adventist Academy is a very loving and safe environment where students easily feel accepted and validated. It is a tight knit community where everyone knows everyone. Because of this, it is easy to get additional help after school from faculty members and even friends. The school also focuses on serving others which helps mold students into better people. Hinsdale Adventist Academy is also an extremely diverse environment where many different cultures and ethnicities are represented. This allows for students to interact with different cultures rather than being sheltered and uneducated. Overall HAA has a positive environment and is a school where each students knows they can turn to their teachers or peers in their times of need both academically and emotionally.

    Middle School Student: I really liked all of the faculty. Everybody was really kind and always looking out for the student's best interests. There were limited sports but that comes with a small private school. The sports that they did offer were very well coached and the equipment was always up to date and in good condition. The fine arts department is very important and they put a lot of their focus in encouraging the kids to do their best, especially in academics. All of their classes were very well taught and the teachers were always willing to meet and help if someone was struggling.

    Parent: My children attend SCS. I have found the academics to be comprehensive without being overwhelming. The teachers love my children. Other parents at the school have reached out to me and shown kindness.

    I absolutely love the cultural diversity found in the classroom. My young children remained "color blind" for a long time, seeing only beauty in the people around them, sweetly oblivious to any differences that divide so many across our nation. What a beautiful multicultural environment for my children to mature in!

    I am also an alumna of the school. I attended in the 80s and 90s. So very much has changed here for the good since that very strict time. I appreciate it when an institution can recognize its weaknesses and work to correct them. I appreciate 2nd chances and am so glad that I gave one to SCS.

    I plan to continue sending my children here as well as enroll my others as they become school age.

    Parent: Our son has been attending Westminster for both middle and high school, and has thrived in the welcoming, Christian learning environment. WCS is a true gem in the Fox Valley area, helping to ensure all students can succeed academically, interpersonally, and spiritually. Small class sizes, dedicated faculty/administration, and varied opportunities for students inside and outside of the classroom help to make this school such a great value. There is a right balance struck between technology and traditional educational strategies for students of all ages at WCS. We have been so grateful for how this school and the wonderful people therein have helped to engage our son's learning journey and further build into his spiritual journey as well. Kudos to the Westminster Warriors!

    23 Best Private K-12 Schools in Illinois

    Senior: I began attending Harvest Christian Academy in the sixth grade. I was hesitant at first, as I was starting there second semester, but now I look back and am so glad that I attended the school. The community at HCA is one of a kind: the teachers genuinely care for you, the students are accepting and loving, and each week chapel is held and continually convicts students in their walks with Christ. Additionally, the food from the cafeteria is absolutely amazing, and the facilities (including the main gym) are beautiful and quite well-kept. One thing that I would improve about HCA would be the dress code. Kids in elementary school through middle school are required to wear a uniform, but over the years these rules have become less enforced. I would vote to remove them completely from the middle school at the very least. Overall, this school is absolutely wonderful and I highly recommend attending. Go Lions!

I appreciate that most of the teachers care more about the students than the grades they are getting. I like the flex schedule and chapel. Something that could be improved would be the athletics. There is no football team. There is only one gym so practice is always a struggle since both elementary and high school use it. There is also room for improvement in the electives that are offered in high school.

    25 Best Private K-12 Schools in Illinois

    Junior: My experience at Chicago Christian High School (within Southwest Chicago Christian Schools) has been overall good, but it could have been better. It is a Christ centered community if you surround yourself with the right people. For someone who didn't go through the SCCS system and just went to the high school, I found it relatively easy to make friends because of all the events that happen throughout the school year (homecoming, freshmen lock in, field trip and etc.). The band program is my absolute favorite thing about CCHS! There's many different bands and opportunities to show your talent! Next favorite would be the tennis team. Although it's small, it's a great place to make new friends before school starts! There are many good things about it but there are also bad. Many things happen at the school that are swept under a rug or kept on the down low, usually they don't effect large amounts of students unless you're involved.

    Parent: We are in our 3rd year as a St. Benedict family and we couldn't be happier. Our 2nd grader absolutely LOVES going to school. She recently started in student council, in SECOND GRADE! The extracurriculars, from Running Club to Dance and Violin, there is something for every child, no matter the interest. They're making great strides in technology as well with their recent 1:1 device rollout, STEM curriculum, new cyber security as well as new safety measures puts them on the cutting edge.

    The culture is fantastic as well. We quickly made lifelong friends and we can all count on each other - it takes a village.

    St Bens is a fantastic school and they continue to make great strides toward becoming one of the leading private schools on the northside.

    Parent: Our family LOVES CCS! Our two boys went through CCS and are much better young men and students as a result. The overall environment at the Catholic School is exceptional. Academically, the students are encouraged, supported, and pushed to do their very best in the classroom. The teachers do an amazing job of reaching each student individually which translates into a trusting, caring, and successful school experience for the student, the parent(s), and also the teacher. In and out of the classroom the teachers and staff also do an extraordinary job of instilling discipline, self-respect and respect for others, thoughtfulness, and a sense of community and personal responsibility. Our boys continue to excel each and every year both as students and as young men in our community and I believe those valuable traits are a direct result of the foundation, mentorship, and guidance that they received as students at the Charlottesville Catholic School.
