In comments on the proposed federal guidelines for stimulus funds, some researchers say there's no evidence for the policies touted. Among education researchers, one complaint about the U.S. Department of Education under former President George W. Bush was that it relentlessly promoted "scientific research in education," while at the same time endorsing some policies that lacked solid research evidence. With recently published draft guidelines for federal economic-stimulus money and Title I aid, critics are beginning to ask whether much has changed under the Obama administration. For their part, department officials are not yet answering the criticism. They did not respond to repeated requests from Education Week to address such complaints. The lack of research reflected in some of the department's school-improvement initiatives is a disappointment, though, to researchers and advocates who were encouraged by President Barack Obama's Inauguration Day pledge to "give science its rightful place" in government decisionmaking. The evidence behind Race to the Top's call for giving priority to states that don't impose caps on the growth of charter schools, likewise, is far from definitive, various commenters said.
