I can honestly say that South is one of the best high schools in the area. My oldest just graduated and will be going to ISU. The staff and teachers express an honest care and concern for the students. I also have a son who completed his freshman year. I am sad to say that we are leaving the area. ...  Read more

CLS is a great school with a very young and energetic faculty. It really seems to motive the kids. There is a termendous amount of participation in the school activities from athletics and clubs to spectators at school events. A fantastic experience for your kids.

We have enjoyed sending through two boys through CLS and both have thrived in the college environment. We beleive the Principal leadership and freedom the teachers receive in developing cirriculum make CLS a unique place.

Crystal Lake South is a diverse school academically. The normal classes are okay (as always quality of teachers varies). There are a decent number of AP classes and a number of good teachers for them. Without the AP program (which, as of my graduation in 1999, had a small portion of students), the school ...  Read more
