In the United States, employment experiences of people with intellectual and developmental disabilities (IDD) have been dominated by discrepancies between recent policy shifts promoting integrated employment for people with IDD and the stagnation of the employment rate in integrated settings for this population. Although there is no direct source for labor force participation for individuals with IDD in the general population, data from the National Core Indicators Project suggest that, in 2015-2016, only 19% of working-age adults supported by state IDD agencies worked in one of the three forms of integrated employment--group-supported, individual-supported, or competitive (individualized and without supports). Twelve percent (12%) worked in competitive or individual-supported employment, and 7% worked in group-supported employment (Hiersteiner, Bershadsky, Bonardi, & Butterworth, 2016). In addition, individual employment supports have not been implemented with fidelity to a consistent model or set of expectations, and participation in nonwork services has grown rapidly (Domin & Butterworth, 2013; Migliore et al., 2012; Winsor et al., 2017).
