They aren't going out in the field to interview friends and family.
A single nice family home in the suburbs could have one kid turn out to be a successful judge and the other a drug addict drop-out (even Trump's older brother died an alcoholic). Good luck measuring that honestly from a college entrance office.
What about a single metric for scholastic aptitude, though? :)
The change moves the onus of metric aggregation from the College Board to individual colleges. We'll institutionalize injustice / poor decision making, but you'll have a choice of which institution will apply the injustice.
Blind admissions. We may even incentivize kids to actually study for college, instead of waltzing in with a seventh grade reading level. If we don't like that recent immigrants outperform natives [of all colors!], perhaps we could perform a serious root cause analysis and address it, instead of papering over the metrics.
