Disabled young people leaving care often experience a more complex transition to adulthood than other youths. Still, policy and services can fail to recognize the intersection between a young person’s care experiences and disability. Drawing on data from a qualitative interview study with 14 social workers who work with aftercare in the Norwegian child welfare services, we investigate social workers’ professional judgements about support for this subgroup of the leaving care population. Our analysis uses the theoretical construct of institutional logics and shows that social workers did not include concepts of disability in their judgements about support for these young people. Instead, the social workers’ considerations were guided by three other organizing principles: a ‘medical logic’, an ‘activation logic’ and an ‘aftercare logic’. We discuss these findings in light of critical disability studies and argue for a more nuanced understanding of disability in social work practice with care leavers. Highlighting disability rights and going beyond diagnosis and categorisations of disabled people can challenge a medical model approach to service provision.
