Forty-two states are now using a data tool called a unique student identifier to follow individual student progress, up from 37 states a year ago, says a report released this month by the Data Quality Campaign, an effort by the Washington-based National Center for Educational Accountability to improve the collection and use of education data.
The report, available online at www.DataQualityCampaign.org, also found that 26 states report that they have or are building data warehouses for education.
