Researchers in field of secondary transition have developed recommendations for increasing the quality of research in the transition field (Mazzotti, Rowe, Cameto, Test, & Morningstar, 2013) including increasing the inclusion of students from diverse backgrounds in research and systematically analyzing differential impacts of predictors of postschool success for diverse student groups in correlational research. Trainor, Lindstrom, Simon-Burroughs, Martin, and Sorrells (2008) highlight the need to understand that diversity and cultural identities are defined by multiple factors, including gender, racial/ethnic identity, disability, and socioeconomic status and that research and intervention development must consider these factors, as well as systems-level (e.g., school policy and organization) factors that affect outcomes. The importance of research with diverse groups is highlighted by research findings, using data from the National Longitudinal Transition Study-2 (NLTS2), suggesting that racially/ethnically diverse youth with disabilities are less likely to be employed competitively after high-school graduation, as are youth from lower socioeconomic backgrounds (Wagner, Newman, Cameto, Garza, & Levine, 2005). Disability label also influences postschool employment. For example, young adults with intellectual disability have much lower rates of paid employment than other disability groups, particularly those with high-incidence disabilities (e.g., specific learning disability, other health impairments; Newman et al., 2011). Outside of employment, systematic differences based on gender, disability, race/ethnicity, and socioeconomic status have been found in postsecondary access and community inclusion (Newman et al., 2011). Researchers have also systematically reviewed transition research to identify predictors of positive postschool outcomes for youth and young adults with disabilities (Test et al., 2009). One factor that has been identified as having a significant and positive impact on postschool outcomes is promoting and enhancing self-determination (Dattilo &
