Useful article in the Washington Post re: standardized testing and fairness: No one likes the SAT. It’s still the fairest thing about admissions.
I’ll post some of the sections on income and scores in a bit, but this section on tutoring caught my eye:
Highly paid tutors make bold claims about how much they can raise SAT scores (“my students routinely improve their scores by more than 400 points”), but there is no peer-reviewed scientific evidence that coaching can reliably provide more than a modest boost — especially once simple practice effects and other expected improvements from retaking a test are accounted for. For the typical rich kid, a more realistic gain of 50 points would represent the difference between the average students at Syracuse and No. 197 University of Colorado at Boulder — significant, perhaps, but not dramatic.
