Despite numerous legislation efforts and increased attention aimed at facilitating successful transition outcomes for students with disabilities, postschool outcomes remain less than desirable (Newman et al., 2011). A variety of factors contribute to these poor outcomes, including a lack of preparation of teachers who work with students as they prepare for adult life (Kohler & Greene, 2004). Thus, the need for trained professionals to provide quality preparation, planning, and services, as students prepare for adult life environments, is warranted (Plotner, Mazzotti, Rose, & Carleson-Britting, 2015). In response to these poor outcomes over the last three decades, an emphasis in training professionals (e.g., secondary special educators, transition specialists) has emerged to ensure adequate transition service delivery (Plotner, Trach, Oertle, & Fleming, 2014). Both secondary special educators and transition specialists typically have a variety of tasks and responsibilities, including transition assessment, planning, career development, and coordinating with adult service providers (Tilson & Simonsen, 2013). In 2013, the Council for Exceptional Children's Division on Career Development and Transition (CEC-DCDT) issued an updated set of transition specialist competencies that defined required knowledge and skills in seven major areas: (a) assessment; (b) curricular content; (c) programs, services, and outcomes; (d) research and inquiry; (e) leadership and policy; (f) professional and ethical practice; and (g) collaboration. However, research has shown that a significant number of special educators do not have competencies related to secondary transition practices (Benitez, Morningstar, & Frey, 2009; Morningstar & Clavenna-Deane, 2014). The literature is replete with studies that support teachers/transition specialists not feeling prepared to properly plan and implement activities that lead to successful transition for students (Plotner, Trach, & Strauser, 2012). Mazzotti and Plotner (2016) found that while transition specialists report using evidence-based practices (EBPs), the majority felt that they did not have adequate knowledge in EBPs related to secondary transition. This is compounded by the fact that many professionals involved in transition planning receive most of their training "on the job" (Kohler & Greene, 2004). To promote sufficient preparation and qualification of special education professionals, the Office of Special Education Programs (OSEP) in the U.S. Department of Education (USDOE) has long provided assistance. Through the authorization of the Individuals With Disabilities Education Act (IDEA, 2004), OSEP assists states and local 742138C DEXXX10.
