WASHINGTON (AP) — Students preparing to leave high school are faring no better in reading or math than their peers four decades ago, the government said Thursday. Officials attributed the bleak finding on more lower-performing students staying in school rather than dropping out.

The news was brighter for younger students and for blacks and Hispanics, who had the greatest gain in reading and math scores since the 1970s, according to the National Assessment of Educational Progress, commonly referred to as the Nation’s Report Card.
