Needs Assessments

The 2012 Needs Assessment that was conducted as part of the first year in the funding cycle provided us with important information about services, products, and activities that are valuable to Pn2 stakeholders. Over 1,500 individuals who are deaf or hard-of-hearing (DHH), parents, and professionals participated in surveys, interviews, and focus groups throughout spring and summer 2012. You can read the complete Needs Assessment or the Executive SummaryThroughout 2014-2015, RES will conduct several mini Needs Assessments to stay current on our stakeholders' needs.  This work has already begun, so stay tuned for exciting developments on these projects!


The RES team conducts mixed-methods research studies to identify and assess evidence-based practices related to transition.  Our studies include qualitative studies, literature reviews, and quantitative analysis. Research findings are presented in a variety of accessible formats including conference presentations, journal publications, white papers, and online resources.  Quick reference summaries of our recent publications are available for download.

National Longitudinal Transition Study (NLTS2) Secondary Analysis

Using secondary analyses of longitudinal data from the NLTS2, RES investigates factors related to postsecondary outcomes for individuals who are DHH, such as English literacy, parent factors, social skills, autonomy, technology, transition planning, and extracurricular involvement.
