Evidence-Centered Design
We are developing in PADI a special case implementation of the evidence-centered assessment design (ECD) framework developed at Educational Testing Service by Mislevy, Steinberg, and Almond. The ECD framework explicates the interrelationships among substantive arguments, assessment designs, and operational processes. The specialization for PADI includes providing higher-level schemas that build in national science standards (ETS’s ECD is content-free), limiting statistical models to a family developed by Wilson and his colleagues, and providing supporting software tools for creating assessment designs within this framework.
