The document presents findings from a comprehensive review of the literature on the topic of nonbiased assessment. An introductory chapter describes the review's conceptual framework. Chapters 2 through 9 present analyses of the following major aspects of the topic (sample subtopics in parentheses): historical perspectives (ancient influences,…

This guide presents a series of check lists to help teachers and counselors provide nonbiased assessment for referred children, particularly those who are culturally different. The first section deals with evaluating the legitimacy of the referral and considers whether parents have been properly notified. The second section, meeting the child,…

This brief report states that legal problems with competency testing have been more procedural than substantive-more concerned with implementation than legitimacy. The right to notice is the most straight-forward and firmly established principle to emerge from competency testing litigation. Students must have fair warning and opportunity to…

To show the difficulty of eliminating test bias and to develop a methodology for distinguishing between the effects of prior knowledge and of skill development on reading comprehension, 207 eighth grade students from rural and urban areas were administered an 18-question reading comprehension test. Quantitative and qualitative effects of prior…

The development of the emerging technology of item writing was motivated in part by the desire to reduce potential subjectivity and bias between different item writers who attempt to construct parallel achievement tests. The present study contrasts four test forms constructed by the combined efforts of six item writers using four methods of item…

Efforts to study the fidelity of translation of attitudinal scales into foreign languages have faltered due to the lack of powerful statistical tests to assess such transformations. This study uses a maximum likelihood factor analysis procedure to compare multivariate factor structures across subpopulations. The results showed that inconsistent…

A brief overview of item response theory is provided, and a 186-item bibliography of books and articles on the subject dating from 1953 to June 1989 is presented. The overview includes a definition of the theory, a discussion of its development and application, and comparisons with classical test theory. All publications in the bibliography were…

The necessity of controlling the order in which trained essay raters for a statewide writing assessment program receive student essays was studied. The underlying theoretical question concerns possible rater bias caused by raters reading long strings of essays of homogeneous quality; this problem is usually referred to as context effect or…

This book discusses tricks for answering questions on the Law School Admission Test (LSAT). The tricks are based on an analysis of 12 editions of the LSAT which have been made public pursuant to New York's Truth in Testing Law. Sample LSAT questions published by the Law School Admission Council are referenced to exemplify the tricks' applications…

This book discusses tricks for answering questions on the Graduate Management Admission Test (GMAT). The tricks are based on an analysis of 20 editions of the GMAT which have been made public pursuant to New York's Truth in Testing Law. Sample GMAT questions published by the Graduate Management Admission Council are referenced to exemplify the…

The reliabilities of 6 item bias indices and correlations among them were investigated for each of the 11 tests of the Iowa Tests of Basic Skills (ITBS). The difficulty and delta indices detected group differences in relative item difficulty. Biserial and point biserial indices detected group differences in item discrimination. The Scheuneman and…

The use of the restructured Graduate Record Examination (GRE), students' entering grade point averages (GPAs), and other variables as predictors of success in graduate school at Texas A&M University (TAMU) was studied. Comparisons were also made to a similar study (Kunze, 1974). A sample of 564 entering graduate students who had taken the…

Since the approval of the Basic Skills Improvement Policy in 1978, the Massachusetts Department of Education has been developing tests and alternative forms for the assessment of student achievement in five basic skills content areas: reading, writing, mathematics, listening, and speaking. Because of the lack of previous research on which to draw…

The Test of Language Development--Intermediate (TOLD-I) was administered to 26 learning disabled (LD) and 26 nonLD elementary aged black children. The subjects were matched for age, IQ, and class placement. Statistically significant differences were found between the two groups on four of the five subtests of the TOLD-I. The data also were…

Formula score theory (FST) associates each multiple choice test with a linear operator and expresses all of the real functions of item response theory as linear combinations of the operator's eigenfunctions. Hard measurement problems can then often be reformulated as easier, standard mathematical problems. For example, the problem of estimating…
