Social communication is a core deficit of autism spectrum disorder (ASD). Speech-Language Pathologists (SLPs) play a key role in evaluating social skills of individuals with autism. Use of person-centered assessment tools in individuals with autism to explore social communication may facilitate improved consideration of perspectives of individuals with autism, which is critical for developing interventions and supports that align with their perspectives and values. An assessment process called the repertory grid can be used to explore one's personal construction systems as they relate to social relationships. This article describes a process for administering this person-centered diagnostic process in individuals with autism using a semi-structured format established by Hess and colleagues. Data obtained through repertory grids may expand upon information gleaned from traditional assessment protocols when evaluating social communication strengths and challenges of individuals with autism. Furthermore, it offers clinicians and clients insight into clients' unique personal experiences and relationships.
