Community Colleges have been around a long time and the savings from living and eating at home with the same first 2 years of the curriculum are an enticing option. Most Community Colleges work their curriculum out with the State schools to ensure a good transition from the community to 4-year school. Some Community Colleges have grown into becoming 4-year institutions. Our local Community College/Trade School transitioned from there into becoming a 4-year College but lost the Trade School part along the way. At Tennessee Tech they still had an active Trade School integrated into the University offering Machine Shop, Welding, etc. Not sure if it is still there now. They also had a heavy water reactor when I was there that has been long gone.
