Parents of dyslexic children often take on additional parental responsibilities as they seek to ensure fair and equitable access to education for their children. Often framed as advocacy, this paper explores the ways in which the term allyship may be well placed to represent the complex primary adjacent and vicarious disability experiences parents of dyslexic children have within schools. Drawing on interviews with 10 Australian parents, this study found that parents of dyslexic children felt they took on additional responsibilities to support their children within the school context and externally. This paper contributes a conceptual lens for viewing these activities as a form of allyship, rather than traditional understandings of advocacy. Findings highlight the need for greater recognition and understanding of the extensive responsibilities assumed by parents of dyslexic children and the ways in which their allyship roles within school settings can impact them.
