Effective vocational instruction is an essential aspect of preparing students with intellectual and developmental disabilities (IDD) for the world of work. We systematically reviewed research on instructional methods used to teach employment skills to secondary students with IDD. We identified 56 studies involving 766 participants with IDD. Four intervention approaches emphasized technology or some other instructional stimulus (i.e., self-management devices, video-based, audio-based, picture and tactile-based) and four focused on live instructors (i.e., direct instruction, augmentative and alternative communication, simulation, peer-delivered). Among the 21 instructional methods used within these approaches, performance feedback, device-assisted instruction, response prompting, and community-based instruction were the most common. We address the extent to which these intervention approaches were effective across students, instructional methods, settings, and outcomes, as well as offer recommendations for future research and practice.

The employment outcomes for young adults with autism or intellectual disability (ID) lag far behind those of their peers without disabilities. Most postsecondary education programs for students with disabilities incorporate internship experiences to foster employment skills. However, the proximity of job coaches may inadvertently hinder social opportunities and independence. We used a multiple-probe, single-case experimental design across three college students with autism or ID to examine the effects of a coaching package on task engagement and social interactions. For all participants, interactions increased and task engagement maintained when job coaches reduced proximity and delivered prompts discreetly through bug-in-ear devices. Participants considered the intervention beneficial and unobtrusive. We present implications for supporting employment preparation within postsecondary education programs.

Building the communicative competence of individuals who use augmentative and alternative communication (AAC) requires intervention and support. This systematic review examined experimental studies involving aided AAC modeling to promote the expressive communication of children and youth (i.e., birth to age 21) with complex communication needs. A search yielded 48 studies involving 267 participants. Interventions were categorized according to three different approaches to aided AAC modeling-augmented input, models as prompts, and models within instructional demonstrations. Although the procedures varied, interventions were generally effective at improving diverse measures of expressive communication. This review provides insight for both researchers and practitioners by describing interventions involving three distinct approaches to aided AAC modeling, highlighting areas needing future research, and offering implications for practice.

Postsecondary education (PSE) programs for young adults with intellectual and developmental disabilities (IDDs) have increased steadily since the passage of the Higher Education Opportunity Act. The purpose of this scoping review was to explore a decade of research pertaining to PSE programs for students with IDDs on college campuses. Online databases were examined. Hand searches were completed to identify studies released from 2008 to 2018 about PSE programs offered on college campuses. Sixty-eight studies met inclusion criteria: 43 peer-reviewed articles across 26 interdisciplinary journals and 25 dissertations across 20 universities. This review identified an increasing trend in research on PSE programs on college campuses. Suggestions for future research and implications for stakeholders were discussed.
