The study was put together by the non-profit Center for Education Policy. It analyzed five years of data from state test scores in reading and math.
Jack Jennings is president of the education policy center. He says there’s good news to report from the data since 2002, when the No Child Left Behind Act was signed into law.
"Reading and math achievement on state tests has gone up in most states. And there are larger gains on the elementary and middle levels than there are on the high school levels. And there are larger gains in math than there are in reading".
Those math gains were reflected in Georgia numbers, showing moderate to large increases.
However, that was before the recently toughened curriculum standards in math. The latest state-mandated testing showed nearly 40-percent of 8th graders failed. School officials stand-by the more rigorous standards.
