A decade ago, the U.S. Supreme Court kept the focus on race as a barrier, upholding the right of colleges to make limited use of racial preferences to ensure a diverse student body. But in a ruling due this month, the court is widely expected to roll back that decision. Such an outcome would shift attention more toward a less constitutionally controversial practice: giving a boost to socio-economically disadvantaged students, regardless of race.
