How does a university know when it needs a revision of its core/general education?

One interesting tool is the AACU diagnostic questionnaire Assessing General Education. I strongly urge every person interested in these issues to truthfully answer the 28 questions; they lay out quite sharply (and in ways a bit depressing) how far from ideal are the typical campus institutions and processes for maximizing the value of a general education/core requirement. In some sense, it is a similar exercise to reading Bok (we/you could be doing so much more...) and yet the shortcomings are the same (a university has limited resources and manpower, and can't have a great core and also a nice pony too).

By the way, UC San Diego has an interesting setup, with six colleges on campus, each one embodying a slightly different general education approach. The descriptions are a bit vague (and there is something slightly creepy about the way many of the colleges emphasize that they are "friendly"... is that something the marketing research focus group told them to put in there?) but nevertheless convey a sense of a different model, abandoning the idea that higher education should have one core, and instead facilitating room for student choice among various general education experiences.
