Both the attenuation paradox of traditional test theory and the assumption of local independence in person-item response theory have caused problems in interpretation. This paper demonstrates that the two are related concepts, and, through this demonstration, both are clarified. It is demonstrated that the breakdown of local independence leads to…

Because test scores are ordinal not cordinal attributes, the average test score often is a misleading way to summarize the scores of a group of individuals. Similarly, correlation coefficients may be misleading summary measures of association between test scores. Proper, readily interpretable, summary statistics are developed from a theory of…

It is suggested that error of measurement cannot be routinely incorporated into the "error term" in statistical tests, and that the reliability of test scores does not have the simple relationship to statistical inference that one might expect. (Author/GK)

Discusses issues in reading assessment, including the concern that tests can not measure the reading process. Concludes that tests will never be more than useful indicators; calls for more research and examination of existing and new types of reading comprehension tests. (MM)

Reliability coefficients of linear combinations of observed scores have anomalous properties which have led to difficulties in the investigation of difference scores and gain scores in test theory. Discrepancies between classical results and correct results obtained from more general formulas, which allow for correlated errors, are examined…

Issues concerning equating test scores are discussed in an introduction, four papers, and two commentaries. Equating methods research, sampling errors, linear equating, population differences, sources of equating errors, and a circular equating paradigm are considered. (SLD)

Reviews selected research, widely-used commercial tests, and recent literature on critical thinking. States that evaluation of critical thinking processes should encompass more than simple tests. Concludes with six guidelines for evaluating critical thinking. (JDH)

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)

Estimation techniques for generating the covariance matrix for two new tests and an existing test without the necessity of any examinee having to take two complete tests is presented. An application of these techniques to linear, observed-score, test equating is presented. (Author/JKS)

The interrelationships among halo and leniency rating errors were examined using simulated rating data. As leniency increased, halo decreased when measured by dimension intercorrelations but increased when measured by standard deviations across dimensions. Implications of these results for the use of the various measures are discussed. (SLD)

The author proposes a greater professional association role in establishing standards for quality assurance in testing. He presents his views as a test developer who dislikes the legal model for resolving professional issues. The use of publications and informational activities to make people aware of the professional standards and how they can be…

Test scores that are not perfectly reliable cannot be strictly equated unless they are strictly parallel. This fact implies that tau equivalence can be lost if an equipercentile equating is applied to observed scores that are not strictly parallel. Thirty-six simulated data sets are produced to simulate equating tests with different difficulties…

An important determinant of equating process efficiency is the correlation between the anchor test and components of each form. Use of some monotonic function of this correlation as a measure of equating efficiency is suggested. A model relating anchor test length and test reliability to this measure of efficiency is presented. (Author/DWH)

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…

Based on a review of the literature, this paper examines criticisms leveled against the communication audit developed by the International Communication Association (ICA) and then offers a modified version of the audit designed to meet those criticisms. Following a brief introduction, the first section of the paper reviews criticisms of the audit,…
