Abstract:

When using item response theory IRT models in educational and psychological measurement, it is standard practice to estimate the operating characteristics of test items from examinees item responses alone. This is the final report of a project that employed Bayesian and empirical Bayesian methods to exploit additional information that is often available about test items e.g. , format, content, or cognitive processing requirements or about examinees e. g., educational background or demographic status. Practical and theoretical results obtained in a series of research reports are summarized.
