In a stunning blow to Mayor Bloomberg's legacy on education, new national exam results show that New York City's math and reading scores have flatlined since 2009

The Bloomberg administration has staked its legacy on closing the gap in achievement between minority and white students, but the national exam results show that the gap has not narrowed significantly between white and Hispanic students or white and black students since he instituted reforms. The city's white students scored better than black and Hispanic students by margins ranging from 22 points to 31 points.
