Every state has different requirements for the courses provided. Some more then others.
Even CNA work. One state you don't need classes. Its on the job training for 6 months then you can be certified. When I got mine I had to do classes for 3 months 3 days a week then I had to take a state exam to even get my certificate.
I also lived on a state line the one state where I did the classes I couldn't work till after I received my certificate the other state I was two weeks into class and was hired and working by myself in a week. This shouldn't be a ok Im gonna do this then enroll.
It takes research. Even if you went to college for years to be a doctor every state had different requirements and state testing and classes that have to be done to even practice.
