I love the idea of sending my kids to community college for all the general education classes. Some of the instructors in community college are superb. They are instructors only and not researchers. And they are also not newbie graduate student teaching assistants. My son, however, has high academic abilities and I bet he will be encouraged by the school district guidance counselors toward a more competitive university.
I agree. But keep in mind a four year college that is not associated with a university should also result in the teachers being professors rather than grad students. That was something I looked at when I was applying to colleges back in the day. I ended up having one or two new teachers in my 4 years at a liberal arts college but not any TAs.
