Graphic symbol collections are often implemented in assessment and interventions with clients with autism spectrum disorder (ASD). The selection of the optimal collection is considered by speech-language pathologists (SLPs) a challenging task. Since limited literature exists on the factors that guide this selection specifically for clients with ASD, this study aimed to explore those in detail, for which a qualitative design was followed. Semi-structured interviews were conducted with SLPs who shared their views on the factors that affect this selection. A thematic analysis of the interview transcripts took place. The outcomes showed that SLPs focus on multiple factors, grouped as SLP-related factors (e.g., training on collection(s) of graphic symbols), client-related factors (e.g., age), family-related factors (e.g., opinions on graphic symbol collections), factors related to graphic symbol collections (e.g., iconicity), practical factors (e.g., cost), and assessment/intervention factors. Assessment methods such as trial-error and dynamic assessment to assist with this selection were also reported. The findings revealed the need to support SLPs in optimal symbol collection selection through evidence-based practices, helping to ensure that symbol selection is tailored to the communication needs of students with ASD.
