Over the past thirty years, obtaining diagnostic information from examinees' item responses has become an increasingly important feature of educational and psychological testing. The objective can be achieved by sequentially selecting multidimensional items to fit the class of latent traits being assessed, and therefore Multidimensional…

Item calibration is an essential issue in modern item response theory based psychological or educational testing. Due to the popularity of computerized adaptive testing, methods to efficiently calibrate new items have become more important than that in the time when paper and pencil test administration is the norm. There are many calibration…

This article describes the 2009 revision of the Dutch Rating System for Test Quality and presents the results of test ratings from almost 30 years. The rating system evaluates the quality of a test on seven criteria: theoretical basis, quality of the testing materials, comprehensiveness of the manual, norms, reliability, construct validity, and…

Previous systematic reviews indicate a lack of reporting of reliability and validity evidence in subsets of the medical education literature. Psychology and general education reviews of factor analysis also indicate gaps between current and best practices; yet, a comprehensive review of exploratory factor analysis in instrument development across…

This article reviews the "Wechsler Individual Achievement Test-Third Edition" (WIAT-III), a newly updated individual measure of academic achievement for students in Pre-Kindergarten through Grade 12 (age 4 years, 0 months to 19 years, 11 months). Suitable for use in educational, clinical, and research settings, the stated purposes of the WIAT-III…

Orlando and Thissen's S-X[superscript 2] item fit index has performed better than traditional item fit statistics such as Yen' s Q[subscript 1] and McKinley and Mill' s G[superscript 2] for dichotomous item response theory (IRT) models. This study extends the utility of S-X[superscript 2] to polytomous IRT models, including the generalized partial…

Samejima ("Psychometrika "65:319--335, 2000) proposed the logistic positive exponent family of models (LPEF) for dichotomous responses in the unidimensional latent space. The objective of the present paper is to propose and discuss a graded response model that is expanded from the LPEF, in the context of item response theory (IRT). This…

This presentation was presented at the 2011 National Conference on Student Assessment (CCSSO). The focus of this presentation is how to validate the common core state standards (CCSS) in math and ELA and the subsequent assessments that will be developed by state consortia. The CCSS specify the skills students need to be ready for post-secondary…

The widespread application of personal computers to educational and psychological testing has substantially increased the number of test administration methodologies available to testing programs. Many of these mediums are referred to by their acronyms, such as CAT, CBT, CCT, and LOFT. The similarities between the acronyms and the methods…

The paper gives an overview of multidimensional adaptive testing (MAT) and evaluates its applicability in educational and psychological testing. The approach of Segall (1996) is described as a general framework for MAT. The main advantage of MAT is its capability to increase measurement efficiency. In simulation studies conceptualizing situations…

A component of a school assessment plan includes traditional IQ testing, often referred to as psychological or psycho-educational testing. Psycho-educational testing can yield information about how a student compares to others in her grade or age group, individual strengths and needs, and recommendations to improve instruction. The intended…

The treatment of validity in the newest edition of "Standards for Educational and Psychological Testing" is quite different from coverage in earlier editions of the Standards and in most measurement textbooks. The view of validity in the 1999 Standards is discussed, and suggestions for instructors of measurement courses are offered. (Contains 56…

Factor analysis attempts to study how different objects group together to form factors with the purposes of: (1) reducing the number of factorable entities (e.g., variables) with which the researcher needs to deal; (2) searching data for qualitative and quantitative differences; and (3) testing hypotheses (R. Gorsuch, 1983). While most factor…

This bibliography provides annotations on over 165 testing sources in the collection of the Humboldt State University (California) Library. Focus is on psychological and educational tests. Information resources are grouped according to information need, including sources of tests or information about tests, and by subject. The Library does not…

This glossary of terms used in educational and psychological measurement is geared toward the non-specialist in measurement. Terms which are considered basic are defined, such as those used in test manuals or educational journals. Definitions are based on current usage in textbooks in the areas of educational and psychological measurement and…
