Diagnostic scores are of increasing interest in educational testing due to their potential remedial and instructional benefit. Naturally, the number of educational tests that report diagnostic scores is on the rise, as are the number of research publications on such scores. This article provides a critical evaluation of diagnostic score reporting…

Paul Newton (2010), with his characteristic concern about theory, has set out two different ways of thinking about the basis upon which equivalences of one sort or another are established between test score scales. His reason for doing this is a desire to establish "the defensibility of linkages lower on the continuum than concordance."…

This article presents the author's rejoinder to thinking about linking from issue 8(1). Particularly within the more embracing linking frameworks, e.g., Holland & Dorans (2006) and Holland (2007), there appears to be a major disjunction between (1) classification discourse: the supposed basis for classification, that is, the underlying theory…

Newton's article (2010) makes three main contributions to the literature. First, it is transatlantic, bringing together literatures that have been dealing with similar problems, using sometimes different methods and certainly with distinctive educational, cultural perspectives. He points out that neither of these literatures has all of the…

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…

A new test of Advanced Placement Physics, explicitly designed to balance both content and cognitive-processing skills, was developed using Sternberg's theory of successful intelligence. The test was administered to 281 AP Physics students from 10 schools during the 2006-2007 school year. Six empirically distinguishable profiles of strengths and…

The history of generalizability theory (G theory) is told from the perspective of one researcher's experiences, describing psychometric and scientific perspectives that influenced the development of G theory and its adoption. Work that remains to be done in the field is outlined. (SLD)

Classical test theory is founded on the proposition that measurement error, a random latent variable, is a component of the observed score random variable. This article traces the history of the development of classical test theory, beginning in the early 20th century. (SLD)

"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)

Discussed are nine questions regarding standard setting issues in educational testing: (1) Should normative or content-referenced standards be used? (2) Different standard setting methods yield different results. Does this finding present a problem? (3) Assess the adequacy of the grounding of various methods of standard setting in psychological…

The inclusion of a position on standardized testing in the 1980 Democratic Party platform established testing as a political and legislative issue. Testing regulations have been introduced in 20 states and in Congess, involving critics and supporters such as: the National Education Association, Nader's Public Interest Research Groups, and the…

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…
