School does not accommodate students and doesn't provide adequate education resources.

OTHS will do just about anything BUT support their staff. If you plan to send your students here, or you want to work here, know there will be no support. Getting anything done is like getting teeth pulled, the district welcomes people who use school devices for inappropriate activities and the incompetence at the admin level is almost baffling. Multiple incidents recently have screwed over the staff and staff havent been getting paid. I wouldnt recommend anyone touch this school with a 10 foot pole.

Weve had multiple kids at OTHS and overall its been a good experience. My kids are in all honors core classes and they have been sufficiently challenged and prepared for college. The music program is hands down amazing and the drama, choir, cross country programs are also top notch. The single time over 6 years I had a concern about an academic issue, it was addressed. The counseling staff is under-staffed and they could use some more AP teachers so the advanced kids can take some more electives sophomore year- but thats pretty normal for public schools nowadays. Overall weve been pretty happy.

OTHS is bad in a handful of ways, definitely more ways than good. Starting off with the building, it's crammed. The halls are narrow, the middle section is filled with intersections that you don't end up making it through. The parking situation is outrageous. First of all there's 3 parking lots, 2 of which is a good little walk from the building, especially in the rain, and the other one is essentially a walk way for students so good luck getting in and out of there if that's where you park. All of them are tiny and have no room which makes no sense considering it's for high school students.. that are newly licensed. And the biggest issue of them all is that they charge over $100 for a parking pass claiming it's for lot maintenance, and the lot isn't maintained..
When it comes to the teachers and the student's learning experience, I can't complain too much. The teachers do all that they can to provide a positive and effective learning experience for the students. However, the staff isn't exactly perfect. From weird history teachers that picks on all the girls the whole class, special ed teachers paying no mind to anything but their phone, and security guards that peek into your stall to see if you're vaping. To be honest I don't know how people may feel about this statement, or even how I do, but I kind of feel like the security actually only cares about students vaping. There was an incident where they had searched every person in a bathroom, obviously leading to student's missing some class time, not to mention the poor students who actually had to use the bathroom. There had been multiple fights in the previous school year (singular) with video evidence of no one but teachers intervening. Where was any of the numerous guards at? They were standing in the bathroom. Students crowd around in intersections of halls causing traffic and no one is there to do a thing about it. Like dude guard the halls.

Admin will sweep almost everything under the rug. Teachers scream at special ed students like no tomorrow and get reported multiple times by families and nothing is done about it. The energy in some of the classrooms is very negative and admin will do just about anything but support their staff.

Bullying is out of control. Does not keep students safe, the zero tolerance policy is a joke. Does not offer many advanced classes. I wouldnt send my dog here on a free ride. Run far as you can drone OTHS.

We moved from Texas where all 3 of my kids had ap classes, ofallon high school didn't even offer ap classes, thank God we came to our senses and moved back to Texas but the year in ofallon really set them back. Now thankfully since we are back in Texas they will all have a high school diploma and at the same recieve a associate's degree thanks to the high school program at their high school here in Texas. Never knew how good we had it here in Texas till we moved to ofallon.

The Superintendent is more interested in increasing her salary than doing what is right for the district. She has a staff of people for a district that encompasses one high school.

The school operates at a high academic level. Most of the teachers care about their students' education. However, the superintendent's office is severely lacking in leadership.

Our son has truly enjoyed his experience at OTHS. From the very first day as a freshman he has felt welcome and challenged. He was part of the very successful band program that OTHS is known for. He took many honors classes that provided him with the knowledge required to excel at the ACT. He feels excited about learning and felt very prepared as he went through the college application process. OTHS is a great public school that far exceeded our expectations.

My daughter really enjoyed this school, but we moved to DC in the middle of her senior years, and she really misses her friends and teachers from O'Fallon. The school she attended in DC is rated as #47 in the Newsweek best high schools in the nation, and yet, it has nothing on the O'Fallon High School. We thought this school was good, but after leaving, we realized it is actually a great one. The academics are as tough as anywhere, the sports programs are very engaging, and the arts programs are just about the best I've ever seen, and I don't mean just for high school...the teachers and the kids are simply fantastic. One aspect that really impressed us was the setup they have with their student counselors. The counselors are very engaged with the parents, and have great people skills. Beware of teachers forcing kids into the advanced classes program. With the hectic schedule (between academics, sports, choir, theater) mine had, I wanted my daughter to pace herself, only to find a lot of resistance from two particular teachers. BTW, she will graduate with honors, and has received several academic and talent scholarship offers.

Great place. Parking isnt good. Lots of food options. Good basketball team ( lost to derrick rose.) Colorguard is the WGI world champs. Drumline was best in 4 states. Classes are entertaining. The teachers are the kind of people you would wanna have a coffee with. Frolics can be good some years. Halls wernt very crowed with the right timing. Yeah, I miss it.

I attended OTHS from 2005 to 2009 and the school is amazing. They offer a wide variety of classes and have a particularly strong science department. Socially, the school doesn't have the huge cliques that most do, attributed to being a military town. Academics is a number one priority, just looking at the level and number of honors courses they have. Their honors chemistry department can be used for duel credit with St. Louis University. The AFJROTC unit is also amazing, encouraging students to do community service, peer tutoring, academic success, and its own variety of extracurriculars outside of the ones the school already offers. There were several teachers there that I love and till talk to today.

I currently attend OTHS and i love it! As a member of the class of 2013, we were the "guinea pig" class, we were the 1st to enter the Milburn Campus and the 1st class to get summer reading projects from freshman to junior years. Milburn was a success, in my opinion, because it prepared the freshman for their high school careers and gave them unique experiences like Challenge Day (amazing experience). There are many course options and many honors classes to take for the more advanced or hard working student and the teachers are awesome and display their personalities making class more fun. There are many clubs, sports, and activities to participate in. Our IMCs are also amazing, there are tons of books to choose from, friendly librarians, comfy chairs, private sound proof rooms, a student lounge, and tons of computers and flip cams for checking out. Unfortunately, sometimes the Smiley Campus smells weird...and all fees are inflated currently because of debts. For example, parking passes are now $50 a semester instead of $50 for the entire year. Overall, attending OTHS is a good experience, we have great incentives for grades and daily, our school broadcast is looked forward to.
