The paper argues that contemporary test validity theory places the consequences of testing on the lives of all college applicants at the back of the test validation argument. It introduces the notion of test efficacy as a process to gather evidence on claims on consequences of testing on all college applicants that can be traced back to validity.…

The Quality Control (QC) Guidelines are intended to increase the efficiency, precision, and accuracy of the scoring, analysis, and reporting process of testing. The QC Guidelines focus on large-scale testing operations where multiple forms of tests are created for use on set dates. However, they may also be used for a wide variety of other testing…

Recently there has been an increasing level of interest in subtest scores, or subscores, for their potential diagnostic value. Haberman (2008) suggested a method to determine if a subscore has added value over the total score. Researchers have often been interested in the performance of subgroups--for example, those based on gender or…

The "International Journal of Testing" (IJT) is the journal of the International Test Commission. It is intended to support the dissemination of scholarly research on tests and test use worldwide. The purpose of this article is to reflect on what has been published in IJT over its nine volumes to date, with a focus on the extent to which…

This article reviews three topics from test theory that continue to raise discussion and controversy and capture test theorists' and constructors' interest. The first topic concerns the discussion of the methodology of investigating and establishing construct validity; the second topic concerns reliability and its misuse, alternative definitions…

In this article, we present a theory of test translation whose intent is to provide the conceptual foundation for effective, systematic work in the process of test translation and test translation review. According to the theory, translation error is multidimensional; it is not simply the consequence of defective translation but an inevitable fact…

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…

As with any test administered across linguistically and culturally diverse groups, evidence suggesting the equivalence of score meaning across countries is needed for valid comparisons. The current study examines the cross-cultural equivalence of score interpretations from the Trends in International Mathematics and Science Study (TIMSS)-1999 from…

This study compares five scoring approaches for a test of clinical reasoning skills. All of the approaches incorporate information about the correct item responses selected and the errors, such as selecting too many responses or selecting a response that is inappropriate and/or harmful to the patient. The approaches are combinations of theoretical…

Presents a model of tests and measurement that identifies test scores with Hilbert space vectors and true and error components of scores with linear operators. This geometric point of view brings to light relations among elementary concepts in test theory, including reliability, validity, and parallel tests. (Author/SLD)

This article focuses on Louis Guttman's contributions to the classical theory of educational and psychological tests, one of the lesser known of his many contributions to quantitative methods in the social sciences. Guttman's work in this field provided a rigorous mathematical basis for ideas that, for many decades after Spearman's initial work,…

"Test Scoring" provides insight into psychometric procedures as used by a professional testing company or in large-scale projects. The book contains an overview of standard test theory, a discussion of factor analytic theory, and an exploration of special applications and problems. (SLD)
