The purpose of admissions testing for almost any organization (businesses for prospective employees, military for recruits, schools for students, basketball teams for players) is to find those who are most likely to succeed at what they will have to do if admitted. The only question is whether these measures are good or bad at predicting who is likely to succeed. In the university case, that means do well in classes and graduate. If they are bad predictors, they need to be replaced with good predictors. If they are good predictors, the problem for groups who are "known to receive lower scores" is not the measurement. The fact that Massachusetts routinely receives lower temperature scores than Florida is not evidence that thermometers are bad.
