To be honest, most folks really don’t care about the ARWU or Times rankings (in the US). As for research, UF is measured by the state (via the performance based model) on research output, faculty awards, etc. These are also used by other rankings systems. UF does well in R&D spending (slightly higher than Georgia Tech and Berkeley), but is trailing in faculty awards, etc. Only way to fix that is by hiring “critical” faculty, which UF has been doing for the last few years.
US News Peer ranking is a hard needle to move. It’s a survey completed by college presidents and provost. How much do these Presidents and Provost really know about the 200 some odd schools they’ve been asked to rank? How much does that have to do with undergraduate rankings?
One critical factor that allowed UF to break into the top 10, was an increase in the peer score, from 3.6 to 3.7 (the first time the UF peer score has increased in 20 years).
UF has past UW-Madison, Illinois, Washington and Texas, in the rankings, even with a lower Peer score. UF does better in the less subjective measures, such as graduation rates, freshman retention rates, test scores, % in 10 Top of HS class, class size, % faculty who are full time, financial ranking, etc.
Academic rep is something that will have to take care of itself. Improve what matters, like graduation and retention rates, student to faculty ratio, and faculty quality (which will translate into awards, R&D, etc.).
At the end of the day, why does UF even care about these rankings? UF cares, because the Governor, state legislature and Alumni care very much about that fact. Setting the goal to be a top 5 public university, is how UF gets these stake holders to financial support UF"s “preeminence” plan with funding and donations. Of course, these stake holders will hold UF to its plan and expect results (hence the states performance based funding program).
