This presentation summarizes the design approach developed for an evaluation of the Helen Keller National Center (HKNC) for Deaf-Blind Youths and Adults. The study evaluated HKNC by gathering data on program implementation to help deaf-blind individuals achieve independent living and vocational goals. The study included residential adult educational programs offered in Sands Point, NY at HKNC Headquarters as well as services offered by HKNC regional representatives and field staff across the United States. HKNC provides services to a wide variety of stakeholder groups including deaf-blind individuals, their families, service providers who support deaf-blind individuals, vocational rehabilitation agencies and staff, and other interest groups. The Rehabilitation Services Administration (RSA) in the U.S. Department of Education identified 14 evaluation questions to be addressed. Westat developed instruments to collect data through interviews, site visits, an email survey, and archival data analysis with 10 different stakeholder groups. #2011Conference #GovernmentEvaluation #DisabilitiesandOtherVulnerablePopulations #HowTo
