Creating fair, accessible, and culturally responsive assessments requires more than a final bias review; it starts during item development. But how do you translate broad principles into practical guidance for item writers, reviewers, and exam development staff? This session explores how one credentialing organization revised its item development standards to better integrate accessibility, bias and sensitivity review, and cultural responsiveness throughout the item development process. Attendees will learn about the decisions, challenges, and lessons that shaped the project and gain practical ideas for strengthening their own item development guidance, reviewer training, and style guide standards. Whether you're updating existing processes or building them from the ground up, you'll leave with actionable strategies for developing more accessible, inclusive, and fair assessment content.
