I have plugged Community Colleges into the spreadsheet noting transfer requirements.
Here is a cautionary note on community colleges.
Community colleges in the U.S. typically have open admissions, and part of their mission is to provide a low-cost path to higher education for nontraditional students, including adults returning to school. We moved to a suburb with "good schools" so our children will have high-performing peers. Very few children from our high school will start at a community college, and none of the best students will. I'd be very wary of putting a gifted child in a community college, because that's not where the smartest people are. Even repeating high school in a "good school" would provide more appropriate peers.
