Interagency collaboration facilitates strong linkages to adult agencies, which improves adult outcomes among youth with disabilities (Kohler & Field, 2003; Repetto, Webb, Garvan & Washington, 2002). State-level transition teams increase collaboration, reduce duplication of resources, improve professional development, and heighten the cross-flow of information (Blalock, 1996; Wehman, 1998). Using social network (Daly, 2010) and focus group analysis (Krueger & Casey, 2000), this mixed methods study examined changes in collaboration, as well as collaborative characteristics and activities, among members of one state-level transition team. Analysis of the social network indicated a significant increase in the network density. Furthermore, focus group results indicated a range of collaborative strategies that built group cohesion and facilitated movement toward improving transition and student outcomes.
