By design, randomized experiments (XPs) rule out bias from confounded selection of participants into conditions. Quasi-experiments (QEs) are often considered second-best because they do not share this benefit. However, when results from XPs are used to generalize causal impacts, the benefit from unconfounded selection into conditions may be offset…

Three areas of concern related to test bias and validity should be considered during the revision of the Standards for Educational and Psychological Tests. The first area concerns the sources and consequences of test bias. Five sources of bias have been identified: numerical bias, role bias, status bias, stereotypic bias, and familiarity bias. The…

States that to demonstrate that a test is not biased for any given use, it is sufficient to show that it is equally valid for different groups. Although an examination of criterion-related validity can indicate bias, it is not ordinarily sufficient to indicate lack of bias, for which explorations of its construct validity regardless of use are…

Reviews the judicial-legal definition of test bias as it has emerged in court litigation, asserting that while technical research studies of test bias have focused either on predictive validity or content validity, the judicial-legal concepts of test bias have attempted to focus on both these issues in a relatively non-technical manner. (JM)

Biased tests systematically favor some groups over others as a result of factors not part of what the test is said to measure. Bias is basically a problem of differential validity. Validity can be discussed in terms of either the procedures for establishing it or test use. Both ways clarify bias in any test. For content and construct validity, the…

For the most part, standardized tests are verbal and presuppose that the test takers know the language, culture, and values of the test makers, who usually represent white, middle class language and values. The communication problems that minority groups face when taking standardized tests include phonological biases (especially when the tests are…

Evaluated 11 of the most popular tests used by school psychologists in Illinois as to their technical adequacy along three dimensions: norms, reliability, and validity. Results suggested that the most popular tests used by school psychologists are not typically technically adequate devices. (Author)

This monograph serves as a nontechnical guide to teachers, counselors, school psychologists, administrators, parents, and others who use the 1974 Standards for Educational and Psychological Tests. The Standards are a concise summary of standards and guidelines for the development, evaluation, interpretation, use, and reporting of information on…

This guide is a compilation of factors considered important in the selection of tests for bilingual/bicultural programs. It is intended for use by test selectors or teachers in bilingual education, and does not presume to be exhaustive or authoritative. Basically the guide consists of questions the test selector or teacher should ask when…

This paper is concerned with the accusations made by such groups as the Association of Black Psychologists in their call for a moratorium on testing, that standardized tests are biased. A biased test measures one trait in one group of people but a different trait in a second group. Evidence about the amount of bias in tests is thin. Bias must be…

The "Griggs vs. Duke Power" decision of the Supreme Court specifies that job relatedness is the only lawful reason for using tests for the purpose of selection when their use results in the disproportionate exclusion of minority group members. One of the main implications of the "Griggs" decision for the test producer and user…

This text is designed to accompany workshop instruction in student assessment technique for the purpose of evaluating bilingual programs. It is addressed to those involved with bilingual programs generally, educators directly involved in planning and implementation, and research and evaluation specialists. The contextual variables that affect the…

The migrant lifestyle, in which a student moves to a new school nearly three times per year, destroys the continuity of educational programs and contributes to abnormally high dropout rates. Educational testing can help improve educational continuity for migrant students by yielding valuable information about their levels of skills mastery so they…

Because of the developmental characteristics of young children, the potential user of tests for educational evaluation needs to be keenly alert to the kinds of decisions which can be made on the basis of testing and to the limitations of testing when young children serve as subjects. The choice of a test to be used will depend on the type of…

Questions often raised about intelligence tests are discussed: (1) the definition of intelligence; (2) the definition of intelligence quotient; (3) the kinds of tests available; (4) validity; (5) fairness to minority groups; (6) use made of test results; (7) differences in results among various intelligence tests; (8) differences in scores using…
