This paper follows a line of logical argumentation to claim that what Samuel Messick conceptualized about construct validation has probably been misunderstood by some educational policy makers, practicing educators, and classroom teachers. It argues that, while Messick's unified theory of test validation aimed at (a) warning educational…

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…

The purpose of this essay is to describe the principles of educational measurement proposed by B. Wood during the 1920s in his dissertation, written under the direction of E. L. Thorndike, and later published as "Measurement in Higher Education" (1923). These principles were selected because they illustrate one of the earliest and most complete…

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…

In mastery testing a linear relationship between an optimal passing score and test length is presented with a new optimization criterion. The usual indifference zone approach, a binomial error model, decision errors, and corrections for guessing are discussed. Related results in sequential testing and the latent class approach are included. (CM)

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…

This issue presents examinations of educational testing, large-scale alternative assessment, small-scale alternative assessment, and educational measurement. These discussions go beyond technical issues to provide a conceptual perspective and a view of underlying histories, theories, applications, and the uncertainties associated with these…

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)

A study compared the performance of 44 applicants seeking admission to an alternative high school (n=19) and nursing assistant program (n=25) at a Wisconsin postsecondary institution on the Assessment of Student Skills for Entry Transfer (ASSET) test and the Nelson-Denny Reading Test. (Applicants who did not achieve a minimum score on ASSET then…

Standardized achievement tests are often misused as indicators of a school's quality or effectiveness relative to other schools. This is an incorrect use because it ignores variation among schools in student abilities, family support of education, student mobility, and other factors. People also misuse tests because they impute to them more…

Different models of performance assessment arise from interactions of three dimensions of assessment: the measurement versus the standards model of testing, quantitative and qualitative assumptions concerning the nature of learning, and whether learning and testing are situated or decontextualized. Addresses difficulties in implementing…

Student test scores are increasingly used to judge the competence of the educational enterprise. Exaggeration of scores is the result of directing attention away from the individual student achievement to the average scores of schools, districts, and states. Implications and recommendations are discussed. (BJV)
