U.S. elementary and middle-school students have made notable gains on national math and reading exams since the early 1970s, while high-school students have made none, according to data released Thursday by federal education officials. African American and Hispanic children are making the most rapid progress, according to results from the long-term National Assessment of Educational Progress, known as NAEP. Still, minority children post lower scores than their white counterparts in every age group. Carnegie Board member Kati Haycock, president of The Education Trust, an advocacy group that works to close the achievement gap, praised the gains but added that "we aren't yet moving fast enough to educate minorities who will soon comprise a new majority of our children."
