In this Request for Applications (RFA), IES invites applications for research projects that will contribute to its Statistical and Research Methodology in Education (Methods) grant program (CFDA 84.305D). IES’s mission is to provide rigorous evidence on which to ground education practice and policy and to encourage its use. The Methods program supports the development of a wide range of methodological and statistical products, including new or improved methods, guidelines or other methodological resources, and software, to better enable applied education scientists to conduct rigorous education research. Researchers should plan to disseminate their methods and tools to applied education researchers who may use them in their own work as well as to methods researchers who may further develop or make use of them.
