When subject matter experts (SMEs) have limited time, every minute matters. Yet traditional workshops often exclude contributors from underrepresented, multilingual, or novice backgrounds. This session introduces inclusive design and facilitation strategies that boost SME engagement, improve equity, and lead to stronger assessments. Drawing from real workshop data, participants will explore tools and communication techniques that honor SME expertise while addressing common barriers such as language, accessibility, and competing demands. Baseline and post-intervention data will highlight effective strategies that can be applied in any workshop setting. Attendees will walk away with a practical toolkit, including a checklist, communication template, and survey questions to implement into their own process. This session is ideal for program managers, facilitators, and psychometricians seeking more inclusive and effective assessment development.
