"range restriction" is always an issue when debating the efficacy of admissions tests. I like this SAT/GPA graph from Randolph Macon College. Its not optimal, as the Y axis has _high school_ GPA, but it's a proxy for college GPA (according to the NPR story HS GPA is a good predictor of college GPA) . When you preselect students on either grades or SAT, notice the correlation between SAT and GPA disappears. But if they let everyone in, the correlation becomes positive. In general, SAT/GPA correlations are strong at weaker colleges, and disappear at elite schools as there is very little variability.

From what I heard, the SATs ultimately don't add very much to this. If you would more clearly explain toi nme the "big difference" that makes the conclusions unwarranted, I am interested. I understand that the SATs provides a modest amount of additional information about potential for college success. Not enough to warrant the misery that preparing for this (what amounts to) annual hazing of HSJuniors from what I've seen. I am not sure that we lose a lot of information by not forcing students to take the exam. I am sure that several corporate entities are sweating the loss of income. I feel worse for the students who don't really benefit much from this. I can easily and happily watch this become an optional and then probably unnecessary part of the college preparatory experience. A good high school student (truly good) will be a good college student.

On the air it sounded like we'd be better off admitting students based on just HS grades, but that conclusion may not be warranted, even using their data: http://www.nacacnet.org/research/research-data/nacac-research/Documents/DefiningPromise.pdf The NPR story is: http://www.npr.org/2014/02/18/277059528/college-applicants-sweat-the-sats-perhaps-they-shouldn-t I did a quick peek at their figures, and found (Figure 40) that, as I suspected, the combined use of grades and SAT scores predicted more variance than either alone. If you had to choose between them, their data shows grades a better predictor but that should not be surprising. I am wondering if, these days, there is a tighter relationship between HS grades and SAT scores (and general cognitive ability) at least in the US, given the tendency to teach-to-the-standardized test. I will never forget my shock when I saw some of my children's homework that looked liked IQ items, of absolutely no use to anyone or anything other than general-cognitive etcetera etcetera etcetera ========================== John W.
