College rankings tie university leaders in knots.
On the one hand, they love them - when they bring good news. On the other hand, they essentially ignore them - when they bring bad news, or the perception of such.
In this country, one of the most famous is the annual U.S. News & World Report "Best Colleges" issue, which tracks universities in all sorts of categories. Around here, the local universities generally do quite well; for example, I cannot remember the last time UNC Chapel Hill wasn't among the top four or five public universities.
But there's much more than just U.S. News out there. Check out this link to a staggering number of methods by which colleges around the world are ranked, listed and evaluated. Think how valuable a resource this could be if, for example, you're considering a college career in Slovakia.
