Abstract
This paper illustrates how Evidence Centered Design (ECD) can be used to address the accessibility of learning-centered assessments, and how such efforts lay a critical foundation for improvements in other aspects of quality, particularly learning efficiency. Specifically, it illustrates how the same basic strategies used to ensure accessibility can be taken a step further to make such systems more learning efficient for students more generally. We draw on Cognitive Load Theory to provide a research-based rationale for this approach. If validated, this approach may lay a foundation for learning-centered systems that are not only more accessible for students with disabilities but also more learning effective and efficient, valid, and engaging for all students.
