Improving the high school drop-out rate has been a perennial priority for policymakers, but which strategies are actually helpful?

The U.S. Department of Education is trying to get to the bottom of that question, and is seeking the all-clear from the Office of Management and Budget to survey a nationally representative sample of high schools throughout this school year, according to a notice slated to be published in the federal register tomorrow.

Information from the survey, which will include 2,000 high schools will be used to help develop a forthcoming report on what sorts of interventions schools are using to ensure students graduate on time.
