With the increasing demands of the modern workplace and a global trend of accountability in higher education, educators and employers pay great attention to the development of students' critical thinking skills…

Both professional certification and academic tests rely heavily on multiple-choice questions, despite the widespread belief that alternate, constructed-response questions are superior measures of a test taker's understanding of the underlying material.

The need to develop measures that tap into constructs of interest to social work, refine existing measures, and ensure that measures function adequately across diverse populations of interest is critical. Item response theory (IRT) is a modern measurement approach that is increasingly seen as an essential tool in a number of allied professions.…

Validity and reliability of the new high stakes testing systems initiated in school systems across the United States in recent years in response to the accountability features mandated in the No Child Left Behind Legislation largely depend on item response theory and new rules of measurement.

Policymakers see VAM as a possible component of education reform through improved teacher…

The need for scale linking in the National Assessment of Educational Progress (NAEP) is discussed, and the specific procedures used to carry out the linking in the context of the major analyses of the 1990 NAEP mathematics assessment are described. Issues remaining to be addressed are outlined. (SLD)
