<p>Alexandre, I mostly agree with your assessment insofar as I suspect it is generally true that it is possible to “skew” performance on the SAT/ACT upward by investing time and money on prep, and/or teaching to the test, so to speak.</p>
<p>I also suspect the admissions department at U of M is talented enough to know how to use these scores in a relative context informed by other indicators and general knowledge about a school’s reputation for rigor, socio-economic makeup, and other qualitative means (re: Clyde10s comment about the scores giving the only standard benchmark for OOS, which I do not believe to be true.)</p>
<p>THAT SAID, in the case of my son, I do happen to know his professionally assessed IQ (from a neuropsych assessment related to a different matter), and it does correlate very precisely with his first and only unprepared sitting at both SAT and ACT.</p>
<p>Re: First and only unprepared sitting…yes, I’m a stupid/naive parent in that I did not think it was necessary to hire coaches etc. for these tests…I thought that colleges might be more interested in knowing first sitting scores, and in his case, that all worked out just fine. ( I only share this b/c the cc community may find it hard to believe that it is possible to have been unaware of all the prepping and pampering that usually goes into what I had viewed to be a simple aptitude test…this ignorance is in part due to the fact that my own college experience was in a different country with a different approach at the time…)</p>
<p>At any rate, I include the following for information for our amusement purposes only, to see if those posting here come up with an accurate correlation or not.</p>
<p>I realize there are many types of intelligence (I hold with Gardner on this subject) and that many of said types are not quantifiable…and I would not bet my life or even make a hire based on the following…disclaimer over, now enjoy!</p>
<p>Cheers,
