ST. PAUL, Minn. (AP) -

New statewide student achievement ratings label 213 Minnesota schools as underperforming, compared to more than 1,000 under the previous federal measurement.

Minnesota developed the Multiple Measurement Ratings system after the state received a waiver from some of the requirements of the federal No Child Left Behind law. Under the new system, Minnesota's 2,000 public schools are judged on students' math and reading scores, plus individual academic growth, high school graduation rates and achievement gaps.

The Star Tribune reports statewide, minority and poor students and those learning English showed better academic growth in math scores in 2012 compared with 2011. But, the new ratings show schools aren't closing the achievement gap in reading. The schools are required to submit plans to address shortcomings.
