What is it?
The AHRQ now requires that those receiving research grant funding from the AHRQ take steps to make their publications and research data publicly accessible. Here's link to the policy: http://www.ahrq.gov/funding/policies/publicaccess/
Publications: Effective February, 2015.
Data: Effective Oct 1, 2015.
Publication manuscripts will be submitted to PubMed Central; the Data Management Plan (DMP) should include a repository where the data will be deposited. The Data Management Plan Policy (effective May 26, 2020) is detailed here.
This plan was developed in response to the White House's Office of Science and Technology Policy’s (OSTP) February 22, 2013 memorandum, “Increasing Access to the Results of Federally Funded Scientific Research."
