Digressing from the specific question on good teaching to consider the wider topic of comparing how colleges and universities "add value" (rather than, as for most college rankings, focusing on the selectivity of their student inputs), I'll mention "The Alumni Factor", a website/set of college reports/book compilation of such reports.

Because they're trying to make money off their alumni survey research, "The Alumni Factor" information is less transparent than I'd prefer. In particular, I can't evaluate how truly representative their alumni samples are (nor how up-to-date).

But they seem to be asking interesting sorts of questions.
