Introduction: Accessibility training frequently relies upon checklist-based approaches to convey important standards and guidance. Such approaches limit scalability and acknowledgement of the user experience. About the case: A certificate program for faculty and graduate teaching assistants who are instructors of record at one university provided an opportunity to develop a learning module about dyslexia. Situating the case: Dyslexic students frequently require alterations to both teaching approaches and document design; however, studies show that some faculty do not see or feel a need to offer any accommodations for this dis/ability. Research indicates that train-the-trainer approaches to accessibility training offer improved scalability and efficacy when it comes to engaging and acknowledging the needs of dis/abled communities. Amplifying voices from the dis/abled community in training also personalizes the need to make content accessible. Approach: This article covers the module's creation and implementation via the iterative Analysis, Design, Development, Implementation, and Evaluation (ADDIE) method. In doing so, it provides a framework for creating similar modules that industry practitioners and faculty can implement within their own organizations. Results/discussion: The COVID-19 pandemic led to fewer participants in the module than anticipated; however, preliminary feedback suggests the approach's efficacy. Conclusion: A train-the-trainer approach that integrates testimonials from the dis/abled community offers a user-focused means of disseminating accessibility guidelines that organizations should consider if looking for rapid scalability for new accessibility initiatives.
