“Should colleges and universities—especially those regarded as elite—use the scores students earned on standardized tests in making admissions decisions?”
Actually, they should ONLY use those scores, at least if they really do care about actually educating people.
Should be 50% test scores, 25% grades and classes taken, and 25 % activities (work, sports, extra-curricular, social interaction (church, charity, etc))
Some people just do not test well, but you can see their capabilities and perserverance in their day to day work.
