Stuart Shieber has a blog post on a new open access policy for the Institute of Education Sciences, which is within the U.S. Department of Education. The policy stipulates that institute-funded research must be made available through the ERIC repository. From the blog post, quoting the policy:

Recipients of awards are expected to publish or otherwise make publicly available the results of the work supported through this program. Institute-funded investigators should submit final, peer-reviewed manuscripts resulting from research supported in whole or in part by the Institute to the Educational Resources Information Center (ERIC, http://eric.ed.gov) upon acceptance for publication.
