The Data Research and Development Center (DRDC) conducts research to improve understanding of the conditions under which educational interventions that prove to be effective in one setting can or cannot be extended to larger or more diverse populations. DRDC also supports investigators carrying out research across the country as part of the U.S. Federal government’s Interagency Education Research Initiative (a collaboration of the National Science Foundation, the U.S. Department of Education, and the National Institute of Child Health and Human Development).
