The aim of this study was to gain a deeper understanding of Swedish social workers’ experience of disabled children’s participation, to discover in what ways their knowledge about impairment and disability, combined with legal literacy and local context influence children’s participation in formal meetings and decision making. Seven focus-group interviews were conducted with 35 municipal social workers from communities in different parts of Sweden. The phenomenological analysis resulted in the overarching theme of elusive participation, in which participation was described as difficult to grasp both in relation to what was supposed to be achieved and what it was meant to result in. Elusive participation entailed a discrepancy between policy and practice, norms and perception of normality, conflicting perspectives and needs, judgment of children’s abilities. These findings underline the importance of creating safe spaces in which social workers have the opportunity for critical reflections and shared discussions about social work practice.
