Where can I find correlation between US News ranking and IPEDS database? I have been building a search tool for colleges and universities in US. I could find most of the data from the IPEDS database. Now I am trying to relate the colleges with US News ranking. I'm trying to find any source of data which could give me ranking of colleges with their UNITID/college name .
Any clues on how to get the rankings data along with UNITID ?
I uploaded a file to wikisend (free and no sign-up file hosting service) with the correlation.
