The Assistant Secretary for Special Education and Rehabilitative Services announces priorities and definitions for the Disability and Rehabilitation Research Projects and Centers Program administered by the National Institute on Disability and Rehabilitation Research (NIDRR). Specifically, we announce priorities and definitions for Disability and Rehabilitation Research Projects (DRRP) on Community Living and Participation of Individuals with Disabilities (Priority 1), Health and Function of Individuals with Disabilities (Priority 2), and Employment of Individuals with Disabilities (Priority 3). If an applicant proposes to conduct research under these priorities, the research must be focused on one of the four stages of research defined in this notice of final priorities and definitions. The Assistant Secretary for Special Education and Rehabilitative Services may use these priorities and definitions for competitions in fiscal year (FY) 2013 and later years. We take this action to focus research attention on areas of national need. We intend these priorities to improve community living and participation, health and function, and employment outcomes of individuals with disabilities.
