These schools are taught by teachers who left the field of business to teach students who want to enter that field after gradation.
Services range from cosmetology to printing to automobile maintenance to pet care. The list is extensive.
This place is a gold mine. You can even go to some of the high schools and have lunch in the dining room that is run by the food department to have a restaurant quality meal for a few dollars!
Every tech school is different, so you need to contact the school to see what services they provide. It will be a very interesting experience.
