I always read that the U.S. New Rankings were very heavily weighted on survey forms that were sent out to academics, so it's very opinion based. But these rankings get a lot a publicity even though many academic types say they really don't mean $hit.
Lets look at ACT scores, if the Board of Regents would ratchet up K-State's entrance requirements a half a notch, the average ACT score of incoming freshman at K-State would go from 24 to 25 or 26 over night. If K-State (the Board of Regents) were to raise the instate GPA requirement to 2.5 and 22 on the ACT (instead of 2.0 and 21), and ratchet up the loophole around a bad ACT score from top 3rd of high school graduating class to top 10% . . . than the perception of K-State would go up on that alone. Plus it really wouldn't weed out that many kids. Come on, if you can't score a 22 on the ACT, and get a 2.5 GPA in reading, writing and math, do you really belong in a 4 year university right out of high school?? (stud football and basketball players being the exception of course).
Lets look at CU, their entrance requirements are supposed to be really tough, but they've got nearly 25,000 undergraduates. I can't believe any school of that size doesn't have a copious amount of if/then entrance loopholes.
Plus we know that a number of Colleges at K-State have pretty strident entrance requirements. You might be able to get into K-State pretty easily but getting into some of the colleges and being allowed to stay in them is a different story.
