<p>This appears to list the colleges that do take the Common App: [CollegeData</a> - Common Application Colleges](<a href=“http://www.collegedata.com/cs/content/common_app_colleges.jhtml]CollegeData”>Student Stories Resources | College Data)</p>
<p>On quick review, the only public universities that appear to do so are SUNY (State University of New York, several different campuses) and the Virginia and Vermont public universities. In the US a “public” university is one set up, controlled, and funded (at least in part) by a State. Your question is one that is not easy to actually answer because as US residents, we just almost always automatically recognize which ones are public universities when we hear a name and never have to really think about answering the question: how do you know. Generally any college named “University of” followed by the name of a State (e.g., Maryland, Illinois, Michigan, California) or Name of a State followed by "University (e.g., Indiana University) is going to be a public university but of course there are others that don’t follow that set word pattern. (Note, though not really an exception, New York University is a private college but it was named after the city not the State) If you are looking at any particular college’s site, just go to the part that sets out amount of tuition – if it shows two tuition numbers, a lower one for in-state residents and a higher one for out-of-state applicants, it is a public college.</p>
