Purpose: The purpose of this tutorial is to educate speech-language pathologists (SLPs) on the need for and positive outcomes associated with neurodiversity-affirming care. This primer will outline what neurodiversity is, why it is central to the provision of evidence-based practice and culturally responsive care, and introduce the reader to neurodiversity-affirming clinical practices. Method: This tutorial is based on a review of literature, including academic research and written works from autistic and disability activists, existence in autistic spaces, conversations within the autistic community, lived experience as autistic individuals, and clinical experience as SLPs. Discussion: SLPs specializing in developmental disabilities will provide services for children with a variety of diagnoses and co-occurring conditions. Consequently, SLPs are likely to work with autistic and otherwise neurodivergent individuals. In supporting autistic clients, SLPs may promote communication development, provide and support augmentative and alternative communication, teach executive functioning strategies, educate family members and/or other members of the support team, and more. As such, it is imperative that SLPs have an understanding of the neurodiversity paradigm, how it relates to providing culturally responsive care, and the positive outcomes associated with incorporating it into our practice. This tutorial provides descriptions of neurodiversity-affirming care principles and definitions of related terms through visuals, discussion, and fictitious case scenarios and examples. Conclusion: Clinicians may use this primer to integrate neurodiversity-affirming care principles into their practice.
