Evidence-Centered Design

Evidence Centered Design (ECD) is an approach to creating assessments, like tests or evaluations, by using research and data to ensure they accurately measure what people know and can do. In the context of general knowledge, ECD focuses on defining specific knowledge and skills that should be assessed, aligning the assessment to these criteria, and using data from actual test-takers to improve the assessment's effectiveness. This method helps ensure that the tests are fair, reliable, and can genuinely reflect a person's understanding and abilities in various subjects.
