It is well established that parents with disabilities are likely to have adverse experiences within the U.S. child welfare system, including disproportionately high rates of involvement and termination of parental rights. However, no known studies have examined the child welfare system through the lens of ableism. This qualitative phenomenological study included interviews with 15 parents with disabilities, 15 child welfare workers, and 15 attorneys who represent parents. Interviews revealed four levels of ableism within the child welfare system: (1) internalized, (2) interpersonal, (3) institutional, and (4) structural. Participants described their own internalized ableism, offered examples of interpersonal prejudice against disabled parents in the child welfare system, and discussed the institutional practice of using parents’ disabilities as a reason to separate them from their children and deny them services and accommodations. Interviews with parents also revealed that ableism across the child welfare system and other institutions could make it more difficult for them to reunify with their children. At the same time, child welfare workers and attorneys noted that disabled parents are disadvantaged by federally mandated reunification timelines. Ameliorating ableism in the child welfare system requires interventions at each level.
