Collaboration is touted as a powerful way to help improve postschool outcomes for students with disabilities. Indeed, collaboration is an evidence-based predictor of improved adult outcomes associated with postsecondary education, employment, and independent living (Test et al., 2009). Interagency collaboration has emerged as a particularly important aspect of collaboration. Morningstar, Kleinhammer-Tramill, and Lattin (1999) reviewed indicators of effective transition programming and highlighted both family networks of support and interagency collaboration as pivotal for transition educational planning, decisionmaking, and resource sharing. Landmark, Ju, and Zhang (2010) also found that interagency collaboration and family involvement were predictive of improved adult outcomes that led to better employment conditions, sustained employment, and independent living opportunities. In addition, they concluded that interagency collaboration during transition planning helped youth with disabilities gain jobs and stay employed with supports. Finally, Noonan, Morningstar, and Gaumer-Erickson (2008) found that inclusion of multiple stakeholders (i.e., practitioners, administrators, and statelevel personnel) during implementation of interagency collaboration, along with sustained interaction between state and local entities, seemed integral to improved collaborative activities. Additional key components in high-performing districts were having a transition coordinator job position and accessing multiple interagency strategies to support collaboration. Passage of two pieces of federal legislation also provides policy levers to facilitate change. To provide key supports and services for employability and employment, the Workforce Innovation and Opportunity Act (WIOA) was passed in 2014 with final rules enacted in 2016 (United States Department of Labor, 2016). Through collaboration with the U.S. Departments of Labor, Education, and Health and Human Services, the aim of the WIOA is to improve the public workforce system for all youth including those with significant disabilities through creation of jobs, training, and retention of workers. Passage of the Every Student Succeeds Act (ESSA) is focused on ensuring in public education high standards and expectations for all students, and 739407D PSXXX10.
