This sounds a lot like Campbell's Law as well: Campbell's law is an adage developed by Donald T. Campbell:[1] "The more any quantitative social indicator is used for social decision-making, the more subject it will be to corruption pressures and the more apt it will be to distort and corrupt the social processes it is intended to monitor."

Here's a little Sunday-morning insight that I thought you might find interesting. I just ran across this thing called Goodhart's L aw, the popular form of which is "When a measure becomes a target, it ceases to be a good measure." http://en.wikipedia.org/wiki/Goodhart's_law Although it is usually applied to business and gov't, it occurred to me that it applies to all kind of issues in education as well. For instance, when the gov't starts measuring the "success "of universities on the bases of retention and completion, most of what then happens is that universities start retaining and graduating people who would not have been retained before (and the value of grades and degrees is thus debased). We don't talk about it that way, of course; we spend a lot of time and money developing systems (both physical and social) that are claimed to help those who would not have stayed and finished otherwise, but this ignores t he ugly but undeniable fact that university is hard and some people decide that it is not for them. But it is hard for them to know that it is not for them before they have done it for a year or two. So, to summarize, the gov't sets t argets, and we set up systems to meet the ta rgets. Some students may be truly helped, but to the exact degree that those systems fail to bring EVERYONE up to level, we retain and graduate students we wouldn't have before in order to meet the targets anyway (otherwise we are considered "failures"). T hat is, as per Goodhart's Law, as soon as passing the test ( the retention and completion quotas) becomes the chief aim, the test fails to measure whether t hings are actually g etting better or worse. It becomes just another part of the system to be navigated. Chris .......
