We have technical college in my area, High school vocational programs are struggling, one local county just outfitted class with all manual machines, local industry toured it and said graduating students would be of no use they do not know CNC. Other issue seams to be getting instructor 40k for full time is what they are offering. But back on subject you can take individual classes at the communtiy college for machining and metrology without all the art appreciation and the like.
