I have a former colleague who earned his Bachelors Degree at the University of Wisconsin, and then went back for some professional development classes at CCAC.
He told me that the quality of the instruction at CCAC was better than Wisconsin, and he actually learned more.
Most of my business class teachers were business men. My teacher for my business law class was a senior partner at a local firm that specialized in business law. The things they taught were from real life rather than books.
You also get a wider spread of students, the majority are adults who are back for either continuing education or, in things like the arts and humanities, just there for the fun of it.
