"Elite colleges have been undermining their own efforts to diversify by giving much more weight to high SAT scores than they did before, according to an analysis of College Board data presented this morning at the annual conference of the American Educational Research Association," The Chronicle of Higher Education reports. "Over the past two or three decades, the share of freshman-class seats that elite colleges award to students with high SAT scores has risen significantly - and risen more quickly than the number of high scores, according to an analysis by Catherine L. Horn, an assistant professor of educational leadership and cultural studies at the University of Houston, and John T. Yun, an assistant professor of education at the University of California at Santa Barbara."
