There are two big factors driving the growing unpopularity of college admission testing:
There is the perennial white vs. black gap in average scores. This has been around forever and it doesn’t change much. All that is different now is that nobody with brains and money really believes at the moment that it will ever go away. In contrast, 15 years ago it was common for billionaires to suggest that their new Ed Reform initiative would close the Gap real soon now because, obviously, nobody ever tried before us to Close the Gap. So, at the moment, the Ed Reform guys are disillusioned and unpopular.
And there is the growing Asian vs. everybody else gap (from Unsilenced Science):
This is almost never discussed publicly, but it has to play a role in the current unpopularity of testing: non-Asian upper middle class parents are seeing their kids get left in the dust by the kids of Tiger Mothers who insist upon fanatical years-long test prep. …
How could we reform college admissions testing? …
2. Shrink SAT to more of pure IQ test. High school grade point average is a pretty good measure of how hard-working students are. But outside of a few St. Grottlesex-type prep schools, it’s not that easy for the admissions committee to figure out just from GPA if the applicant has the raw processing power to thrive in a difficult major.
Moreover, there are more than a few diamond-in-the-rough kids, usually boys, who have the smarts to make something impressive out of their lives but were bored, unchallenged, distracted or whatever in high school.
For example, analogies were dumped from the SAT about 17 years ago For Reasons involving The Gap. But analogies are highly g-loaded and perhaps tougher to massively test prep for. So instead of helping blacks narrow the gap, getting rid of analogies helped Asians pull away.
So, shorten the SAT from multiple hours of stuff that can be massively test-prepped to maybe an hour of the most g-loaded, hardest to prep questions.
The SAT changes 17 years ago changed the SAT scores to reflect hard work more and IQ less, and lo and behold that’s when Asians started doing even better. Maybe go in the other direction: use SAT as an IQ test, and use school grades as a measure of hard work.
