    Do not listen to parents describe what a school is like. They get the propoganda that is fed to them by the school. Take it from an actual student this place is no where near as top notch as they like to think. Pathetic sports with overly demanding coaches administration that cares about their bottom line more than the well being of the students security guards picked straight out of the nursing home food that prisoners at dupage county jail eat (literally same company provides for both institutions) watered down academics because "every kid is an honors kid" and teachers that are overpayed in proportion to how much they actually do. Not to mention the pure wastefulness of the funds. There is a smart board in nearly every classroom over $5000 a pop. And you know what the teachers do with them? Pull down the projector screens in front of them because they are so buggy and inefficient that it's better to just use handouts and projector screens. This is a miserable place to be and nobody should be fooled by the smoke and mirrors the administration puts up. I hated every second of my experience at glenbard south.

    I am an alum from around 2007-2010 grad year (prefer to stay anonymous). Honestly this school is a small school so therefore it is what you make it. If you are a motivated student who wants to do well and wants to get along with teachers and hang out with the right people you will do well. That's why I am currently doing very well in the real world. However if you have some needs beyond being self motivated (not that you are a bad kid) then this might not be for you. Not all kids are mature enough to be able to do this. As the community around this area is relatively well off there are certain limitations with that but there are certain benefits. I enjoyed high school overall (although I seriously disliked some teachers and some aspects but who doesn't?). As far as public schools go this is a great one. Also security is minimal because it doesn't need to be better. Its a great area and there is a certain trust with students and teachers. Lastly I agree with the person who discussed the separation between honors and regular. Honors students are regarded above the "regular" kids which creates an environment in which high performers are rewarded (AKA just like the real world).

    I have the distinct honor of being a Glenbard South alumni as well as a parent. As a product of this small but proud school I was thrilled to be able to find a home in the area so my sons could have that same opportunity. Smaller class sizes offer more one on one teaching if necessary and tons of AP class options. Excellent teachers a caring and involved principal along with a challenging academic program is what makes Glenbard South such a fantastic school! I honestly don't believe my son would've been able to get an academic scholarship to the University of Illinois without having the benefits of academic rigor this school instilled in him.

    Pros Stellar academics (particularly for honors/AP track) active extracurriculars flexible course choice personal attention due to small size Cons Athletics are lackluster somewhat cliquish honors and regular kids divided socially administration considers students' views little when making decisions. Overall it's a good school. I'm glad I went here.

    The honors program is so diluted my daughter is getting bad grades from pure boredom. Not a good idea for anyone who's kids are involved in the honors program.

    As far as schools go i think gshs is a good one although it may be lacking in a few areas it's a small school which is nice it's in a safe location and it's well rounded in many aspects as far as having a variety of sports clubs and classes. As a student there i must say i rather enjoy it.

    Honestly this school isn't exactly the best place on earth like these parents say. They don't attend the school. But I did. I hated it personally. I mean it was alright to some extend but I much rather attend a different highschool. The security is horrible. I know a little birdie who snuck her boyfriend in the school and he got by with 5 classes. What does that tell you about the security? And might I add...they police offers are mainly over 50. What coul they do when there is a crisis? Nothing.

    Great high school. There is a lot of division between the honors and regular kids. If you are not honors don't plan on being challenged to much. The school caters to the honors kids. If you are in any honors classes or AP classes you can really go places. If are just a 'regular' student you still have many opportunities but you're on your own.

    Scholastically top notch. My children diid well as a result of the programs directives.

    This is a fantastic school. It offers a variety of classes including a wider-than-usual selection of AP classes. The music program is exceptional and academic excellence is stressed. Glenbard South is a very competative school for a public high school and dozens of academically-based clubs and after-school activities are great suppliments to the already fantastic leaning environment.

    This is a wonderful school with amazing teachers and students. My daughter was a new student last year and she made friends amazingly fast being that she is so shy. The teachers were wonderful at helping her catch up seeing as we moved with only seven weeks of school left. She felt very welcome and had wonderful grades thanks to the fabulous staff at Glenbard South. I would recommend this school to anyone and everyone.
