Recent discourse has identified significant issues surrounding the lack of diversity in autism-related research. However, recent efforts have called for the regular use of diversity advisory boards (DAB) in autism-related research to improve the inclusivity of underrepresented and marginalized groups included in the growing autism scholarship. This article outlines the development and implementation of a DAB to support the design and evaluation of an innovative intervention, "WorkChat: A Virtual Workday." Specifically, "WorkChat" focuses on improving knowledge and practicing conversational skills with virtual customers, coworkers, and supervisors to support workplace interactions for autistic transition-age youth. Here, we share guidelines for developing, utilizing, and maintaining a DAB, as well as recommended practices and future implications for implementing DABs in autism services research while using the "WorkChat" DAB as a case study. The goal is to support the further use of DABs as a means of significantly improving the inclusion of underrepresented and marginalized identities including racial, gender, and sexual minorities, and individuals with disabilities in autism services research.
