Even with an open access institution there's a self-selection factor.
Did the paper give demographics on their sample population showing that it was
representative of all college graduates, not just all grad school applicants?
Reply:
I misrepresented the study slightly. The university did not have an open-access
policy. Rather, they admitted applicants without reference to GRE score. In
addition, they only report the standard deviations of GRE scores for the
applications and for those who attended. Because they were similar, the authors
state that there was no restriction of range in GRE scores. Under these
circumstances, the validity coefficients were higher than usual.
Dear Tipsters,
Interesting correlations here for the GRE from an open access institution:
Huitema, B. E., & Stein, C.R. (1993). Validity of the GRE without restriction
of range.Psychological Reports, 72, 123-127.
Correlations of the GRE with four graduate school performance criteria were
.60, .70, .55, and .63. (!)
Sincerely,
Stuart

"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.

I suspect that the College Board - and various test prep companies - will want
to shoot holes in this study. 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.

I usually don't read articles with "executive summaries" but this got air time
on NPR this morning. 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
