Abstract\nPoints of interestIn this article, we build upon a historical and critical analysis of de-institutionalisation strategies, representing a fundamental shift in disability policy and practice starting in the 1960’s. We state that de-institutionalisation has commonly been interpreted and translated as a vital ‘transition’ – referring to the dismantling of residential care and institutions – in rights discourse, policy, and (self-) advocacy. Whereas de-institutionalisation currently often interferes with neo-liberal welfare state reforms, we argue that the focus on ‘transition’ tends to ignore controlling and oppressive institutional care cultures that circulate in a variety of settings, whether ‘community based’ or not. In this article, we elaborate on Francois Tosquelles’ Institutional Pedagogy as a theoretical framework to radically ‘transform’ (residential) care in a wide variety of settings. Our analysis is based on qualitative interviews with residential care providers and (self-) advocacy groups, and offers a more in-depth insight in the complexities of de-institutionalisation as ‘transformation’.The common interpretation of de-institutionalisation states that large institutions for citizens with a disability need to be dismantled. It is claimed that institutions should be replaced by care and support in society to realise human rights for all.The article examines how closing down institutions hasn’t changed institutional ways of thinking, like oppressive and controlling ways of acting. It also has not facilitated inclusive relations. We state that de-institutionalisation should also focus on transforming the culture of residential institutions, no matter where this care and support are organised.The article uses a theory of Francois Tosquelles, Institutional Pedagogy, to rethink and transform institutions.The research builds on interviews with board members of care organisations that are changing, and with (self-) advocacy groups in Flanders.The article describes the need to transform residential institutions in a radical way. After all, residential care might still be the choice or last resort for citizens with a disability. [ABSTRACT FROM AUTHOR]
