The Business Journal Top 25 lists this week include two that focus on education. The first is the largest in-state four-year colleges and universities, and this year we are also highlighting the largest two-year colleges based in this area. Based on enrollment going back to fall 2011 (the more recent fall semester is not always available for all institutions when the list is published), the No. 1 four-year institution in the state is the University of Wisconsin-Madison.
