Evidence-Centered Design: A Summary
In this brief, Herman and Linn define evidence-centered design (ECD) and its relationship to PARCC and Smarter Balanced consortia assessments. ECD is a principled approach with interrelated stages for assessment development and validation. The main purpose for ECD is to support a close correspondence between the claims about student performance that a test is designed to evaluate and the nature and quality of the assessment evidence that is used to draw inferences from student scores.
