Nonspeaking autistic people remain largely absent from higher education because rapid, real-time participation norms and uneven accommodations limit who can meaningfully participate and influence decisions. This neurodivergent-led session shares a practical framework for building inclusion-by-default systems. Using the TYPE project – six nonspeaking autistic co-designers and interdisciplinary collaborators developing an adaptive typing-based training system – as a case study, we show how communication-access practices and shared-authority practices enable nonspeaking collaborators to co-lead design and decision-making. Attendees will map their access ecosystem and leave with a draft “next 30 days” change to implement in classrooms, meetings, labs, and committees.
