Current methods that simultaneously model differential testlet functioning (DTLF) and differential item functioning (DIF) constrain the variances of latent ability and testlet effects to be equal between the focal and the reference groups. Such a constraint can be stringent and unrealistic with real data. In this study, we propose a multigroup…

Complexities of test fairness are described in nontechnical language, and their implications for the selection procedures practiced in our society are discussed. Four clearly distinguishable models of fair selection are presented: the Cleary, or traditional, model; the Cole model; the Thorndike model; and the Darlington model. A distinction is…

The common approach to studies of predictive bias is analyzed within the context of a conceptual model in which predictors and criterion measures are viewed as fallible indicators of idealized qualifications. (Author/PN)

Three types of test bias are discussed: content bias, atmosphere bias, and use bias. Use bias is considered the most important. Tests reflect the bias in society, and eliminating test bias means eliminating racism and sexism in society. A six-stage model to eliminate racism and sexism is presented. (Author)

Models proposed by Cleary, Thorndike, Cole, Linn, Einhorn and Bass, Darlington, and Gross and Su for analyzing bias in the use of tests in a selection strategy are surveyed. Several additional models are also introduced. The purpose is to describe, compare, contrast, and evaluate these models while extracting such useful ideas as may be found in…

The authors suggest that efforts to comply with the protection in evaluation procedures provisions of P.L. 94-142 (the Education for All Handicapped Children Act) have been characterized by attempts to identify a single fair test for use with specific groups of minority children, and that such efforts will not result in improved efforts to…

This publication reviews issues and processes in the quest for less-biased, least-biased, non-biased assessment. It is intended to aid the school psychologist in assisting all individuals in placement or program decisions for school-age children. The first section articulates the common sources of bias in assessment and identifies concepts…

The Nonbiased Assessment module contains seven sections that provide information on various issues relevant to the construction of programs for assessing minority group children. Each section, in addition to the discussion of the topic, contains a list of objectives for the workshop participant or reader, a pretest, simulations, and an annotated…

A defense of the System of Multicultural Pluralistic Assessment (SOMPA) in response to previous articles in this issue of this journal is presented by the test developer. The defense is detailed and addresses each previous article. (JKS)

Test publishers and the users of standardized IQ and summary-score achievement tests have failed to consider the problems associated with testing the minority child. Since the results of these tests are used to determine the education, economic, and social future of children, a harder look at the minority child's cultural background is essential.…
