Naomi Gafni, director of Research and Development, National Institute for Testing and Evaluation, Jerusalem, Israel, has devoted a substantial part of her career to the development of admissions tests and other educational tests and to the investigation of their validity. As such she is keenly aware of the complexities involved in this process.…

Psychometric practice does not always converge with the advances of psychometric theory. In order to investigate this gap, the authors focus on the 10 most used psychological tests in Europe, as identified by recent surveys. The article analyzes test manuals published in 6 different European countries for these 10 most used tests. A total of 32…

The article "Thinking About Linking" by Newton (2010) presents a novel philosophical perspective on the way that educational assessments should be linked. Newton starts by describing the linking framework as it was characterized in various publications and identifies a cross-cultural dimension in the definitions and uses of test…

Results obtained when a procedure for assessing the questions on uniersity mathematics examinations to see what skills were needed for their solution are given for a sample of 1400 questions set during 1976 in 10 British universities. The method is a way of focusing rational argument. (MNS)

Discusses classical test theory, including test construction, administration, and use. Covers basic statistical concepts in measurement, reliability, and validity; principles of sound test construction and item analysis; test administration and scoring; procedures for transforming raw test data into scaled scores; and future prospects in test…

Tau-equivalence means that two tests produce equal true scores for individuals but that the distribution of errors for the tests could be different. This paper examines the effect of performing equipercentile equating techniques on tau-equivalent tests. (JKS)

In an attempt to restore the symmetry and balance between the study of person and item variation, this paper presents a novel methodology construct specification equations, which allows one to ascertain from the lawful behavior of items what an instrument is measuring. (Author/PN)

On the basis of the characteristics of criterion-referenced tests, the contribution of German research to the development and application of criterion-referenced tests is discussed. (PN)

Diagnostic testing confronts several challenges at once, among which are issues of test interpretation and immediate modification of the test itself in response to the interpretation. Several methods are available for administering and evaluating a test in real-time, towards optimizing the examiner's chances of isolating a persistent pattern of…

Discusses the use of standardized test results as a guide to developing curriculum content and uses data gathered at Hellgate Elementary School, Montana, as an example. (JC)

Discusses the use of standardized test results as a guide to developing curriculum content. Discusses such a plan being used (and offers data gathered) at Hellgate Elementary School, Montana, as an example. (JC)

This text was written to help the reader acquire a base of knowledge about classical psychometrics and to integrate new ideas into that framework of knowledge. The material is organized into five units: (1) introduction to measurement theory; (2) reliability; (3) validity; (4) item analysis in test development; and (5) test scoring and…

A multi-faceted model for the selection of answers for multiple-choice tests was developed from the findings of a series of exploratory studies. This model implies that answer selection should be curvilinear. A series of models were tested for fit using the chi square procedure. Data were collected from 359 elementary school students ages 9-12.…

The idea that validity should be considered a property of inferences, rather than of assessments, has developed slowly over the past century. In early writings about the validity of educational assessments, validity was defined as a property of an assessment. The most common definition was that an assessment was valid to the extent that it…

A look at the history of intelligence testing suggests that those most closely allied with intelligence testing were often least able to see the larger issues. Input is needed from those who have examined broader currents in the history and sociology of ideas. New ideas must be cultivated to avoid redundancy in the field. (SLD)
