St. John the Baptist Diocesan High School is truly a school of academic excellence. It is an amazing school. The family atmosphere you feel the moment you walk through the door is something you will not experience at any other school. The academic program is very challenging and top notch. The teachers and administrators are truly supportive, and always willing to go the extra mile for their students. The students are very thoughtful and respectful - true ladies and gentlemen. Overall, Saint John's is a great school where the students get an excellent education, in addition to their outstanding athletic programs.

I just completed my first year at SJB. Coming from a public school, I saw a big improvement in both faculty and the students. I became more challenged in my classes, whereas the district I live in makes classes easier, therefore, simple for me. SJB invited the freshmen in, and provided us with all the information we could ask for. The faculty are truly one of a kind. Not only are they great at teaching the students, they are caring and help each individual student's needs, no matter how little it may be. The atmosphere is always friendly and there is never a day that bores me. Overall, the students that attend SJB are well-mannered, and the group of friends I have made are truly one group that I am very close to. A great aspect of St. John's is the arts. Some schools do not fund the arts well, or put any importance in it, but St. John's is quite the contrary. Our musical is top notch, where everyone; students, faculty, and parents are impressed with the show they see. Our music program features great teachers that don't just teach music, but express their love for the arts, and mentor the students to do the same. SJB has truly become a 2nd home to me, as well as my peers.

AMAZING SCHOOL... This school is beautiful, immaculately clean with fllors so shiny they look like glass, beautiful bathrooms with real tile not the public school industrial tile... Teachers who truly care and give 200 % to the students.. Discipline, pride and sense of community and faith are instilled in every student. Were considering another CATHOLIC HS in area but this one was the more recommended one and now that my child is their I see why. My child is excelling and absolutely loves the school and loves going to school! Best decision we ever made!

This school has totally gone down hill. Four years ago when my first child attended the school was well run and organized. I would have given the school a 4-5 star rating. Now the school is terrible since the old administration left. Kids are disgruntled and frustrated, teachers are inexperienced and insubordinate to parents. What was once a very pleasant environment has turned stress filled and very unhappy. Plus the school is filthy, and I mean filthy. My daughter fears going to gym because of the mold and slime on the floors. Its disappointing but I can not recommend St. John's anymore. We are switching to St. Anthony's.

Seriously, this school is not very good. It is not Chaminade or St. Anthony's and it knows it. It has great kids though just too bad the admin treats them like 1st graders. I went there because I live in North Bab and my parents didnt trust that school but I wish I went there. SJB tries to squeeze every penny out of u too, it never stops. I was on track and it cost $300 to be on the team, and the charge kids for dress down day's. Its a disgrace but thats nothing compared to how bad the teachers are. They test like its harvard but teach like its 3rd grade. I hated it but made a lot of friends.

My experience in the school was up and down. The school is disciplined and no cell phones, etc. but i think they treated us like grade school kids instead of teenagers about to become adults. I thought I was getting a decent education until I took the ACT/SAT and realized that this school was way behind in preparing me. I had a b+ average and thought that would get me in a top tier school but the fact that it was from a "prep" school didn't matter. I got accepted to a good school, not great and was shocked how behind I was. I would say go here if your public school is real bad but if its decent, go public, its not worth the money and it probably is not a better education either.

This school was good. The past principal was able to incorporate a feeling of pride and enthusiasm within a disciplined environment. The new principle can not do that. The balance has swayed to one of absolute discipline without any compassion or care of each students future. The new principal is an over emotional tyrant who doesn't understand why we send our kids to the school. The grading system and the teachers policies make it nearly impossible for students to get grades high enough to be admitted to a good college. 85 in St. John's is a great grade but St. John's isn't Chaminade and the Harvards of the world don't know the difference. If you want your kid to get into a good school, stay away from SJB and save your money. A 95 in public school carries a heck of a lot more weight than an 85 at SJB. Half the teachers are in their mid 20's and they like grading super tough as if it is a sign of a good teacher. STAY AWAY IF YOU CARE IF YOUR CHILD GOES TO A GOOD COLLEGE.

One of the best schools on LI! Great academics, arts & athletics. Far better than any public HS! Zero tolerance for troublemakers (bullies & druggies). Students & paculty have pride in their school and themselves.

I'm a parent now and I also went to St. Johns and loved it. You know I read some negative comment about the school and faculty. When I went there was discipline but that was good and yes the teachers cared and I'm sure they still do. We can't make every student happy its up to the individual. We all make our own destiny. I believe when I was there we started the day off with prayer that was the best thing to do. Your day was first God then school work and also great friends. We use to have study groups and help each other out in class and out of class. We all worked together as one unit. We had great team spirit and I believe love for one another even though we did'nt outwardly say it. What did I learn at St. john the baptist; Love,respect,kindness,loyalty,friendship, knowledge,wisdom,discipline,Jesus.

I went to SJB 25 years ago and now I'm sending my daughter. She absolutely loves it! I believe kid's need discipline,safety, structure, Religion in their life, and teachers who really care. This school has all of those things and more! It is like a big family.

This school is amazing!!! The four years I spent in high school were filled with great experiences and thanks to SJB I was definitely prepared for college! It is 100% worth the money. I had to get a job sophomore year to help pay for my tuition and I do not regret that at all! I would do it all over again! Saint John's is great.

there are a lot of conflicting reviews here so i'll give it to you straight, if you want a good education from sjb you can get it. we have some great really teachers willing to help you if you're having trouble and so many elective and AP classes i wish we had a longer day so i could take them all (we have 9 periods) But if you dont want to try and you complain about the rules then you won't like the school. its a no BS place, they won't put up with junk if you dont want to be there; it gets in the way of the kids that do. i'll say it again, if you want a good education twhere people really care about how you are doing, both academicly and as a person, hen SJB is the way to go. i personaly love it there.

I have gone to this school for 1/2 a year now. Already I can tell that though it is a challenging school it will prepare you for college. The Teachers respect you as a person as long as you respect them as well. I'd reccomend this school to anyone who lives on Long Island.
