One problem with all automotive schools is simply this, they are made to teach all this in two years, and automotive should be at least a four year school. You cannot teach this material in two years. Two years and you are only in an introduction. Maby 20 years ago, but this is another world. The fact is that automotive technology because of emmisions and competition has multiplied in complexity so quickly, probally faster than any other industry short of say military related.
I am an ASE Automotive Master Technician. I work for a Goodyear Service Center. I started out doing General Service, and there is a lot to learn there. I then was an assistand to one great tech, and now I am on my own and let me tell you, I have a lot to still learn. There are so many things you cannot learn in a classroom.
Don't listen to these fresh out of school types that tell you how much they know. There was a guy that posted on this forum that used to list his "certifications" in his signature, and claimed he was fresh out of UTI and didn't need experience because his instructors taught him everything. The truth is, your going to be in the buisness at least 15 years until your really, really good. I've met a lot of techs in my life, and it isn't eas out there.
Maby look into a dealership and tell them you want to learn, many of them will send you to school if you show the initiative. However, you will become dealer specific. I guess I perfer to be a jack of all trades.
