I live in a small town in Southern IL and I'm actually going in this week to fill out paperwork to try to get into a CNA class in my county. The secretary told me that as long as I make a certain amount of money or less I can get into the program for free, I'm assuming financial aid or the state will pay. It's a 12 week program (6 weeks class, 6 weeks clinical) and it's Mon-Fri 8:30am - 3:30pm. It's going to be pretty intense, but worth it! I was taking a CNA class at my local community college earlier this year, but I was having to pay out of pocket and I couldn't afford it so I had to drop out

.
Anyway I found it by doing a google search for nurse aid classes + my zip code. It doesn't hurt to try and you never know what you may find.
