Of course it's not quite so binary. The dean wants a strong applicant pool as well as to dissuade helicopter parenting. I don't believe it's a contradictory stance she's taking.
If you are a gatekeeper to an area of high value, and if you set demanding test standards, then people are going to try to teach the tests. All the talking about good parenting in the world seems unlikely to change that.
In that position, one can either change the standard to support that which one desires, (Have a discussion that goes something like, “If we are interested in educating young men and women of resilience, how do we encourage and/or test for resilience?”) or one can complain. I've yet to seen any indication that complaining will improve matters in a situation where the majority of the incentive seems to lie on the side of those who act contrary to your desires.
What teen would be able to have the breadth and variety of experiences that seem to be required nowadays to stand out in a university application unless they have a set of parents that make them possible?
