Here's how it worked for me: I decided I wanted to go to school for nursing, I applied at the school in my area that had the shortest waiting list, they told me in order to get on the waiting list, I had to be certified as a nursing assistant and this school offered the CNA class.
Part II: once I became certified, I got a job with the state and found out that they would have actually paid me to get certified on their site themselves.
I know that sounds a little goofy...& it was. A lot of people would get hired at this facility just to get certified (by the way, this place paid you hourly just to take their CNA class) and would quit immediately after.
I'm originally from MN, so I know a LITTLE bit about the schools. Of course, I have no idea what part of MN you're from...but...Inver Hills Community College is rumored to have an excellent nursing program. And there's another technical college I'm thinking of, too...maybe Dakota Tech?
I would just find out what schools in your area offer the nursing program and go from there. It's an easy 6 week, or something, course.
Good luck! And congratulations on your decision to be CNA...it absolutely changed my life
