Included in prohibited areas in FCCA
“(15) Any building, classroom, laboratory, medical clinic, hospital, artistic venue, athletic venue, entertainment venue, officially recognized university-related organization property, whether owned or leased, and any real property, including parking areas, sidewalks, and common areas under the control of a public or private community college, college, or university”.
While they failed to mention the parking lot exemption, it looks like they correctly paraphrased the law.
That might apply if the student had a CCL. But since they are there to take the CCL class, that seems unlikely.
Many CCW training classes restrict or limit bringing a firearm to certain areas. Here are a few that I found with a quick search.
Midland Academy, Orland Park
“Do not bring firearms or ammo into the class, please secure them in your vehicle until you are asked to bring it into the class and then only unloaded firearms are allowed”.
Illinois Concealed Carrry, Oak Brook
“Q: I have registered for a class. Do I need to bring any firearms?
A: NO. They are not allowed in the classroom setting. The Utah CCW Permit requires no live firing, but the Florida permit does. Illinois Concealed Carry will provide the firearms for all classes. There will be an extra small fee for ammunition”.
Champaign CCW, Champaign
“Please leave your firearm/ammo in your car during classroom hours
(If you want to bring it inside, tell the instructor and he'll tell you where to secure it.)”
