An item content criterion, independent of the test psychometric characteristics, of classifying items as biased is described. It was used with a sample of female adults in a training program for administrative secretaries. The minority group in the study were Hispanic immigrants. The majority group was a mixture of Blacks, English speaking…

The purpose of the present study was to examine the accuracy of indirect trait estimates, i.e., estimates of some primary trait obtained from a second measure which have been equated to the first. The California Achievement Test in Reading was the primary measure and the Prescriptive Reading Inventory was the indirect measure. Four kinds of…

Through reference to the "Edmonton Grade 111 Achievement Study: 1956-1977 Comparisons" this research attempts to dispel the uncertainty associated with current curricular validity of old tests. Examines five standardized tests used in the Edmonton Study, which were first given in 1956 and designed to measure basic skills. (Author/RK)

A computerized adaptive test (CAT) may be modeled as a closed-loop system, where item selection is influenced by trait level ([theta]) estimation and vice versa. When discrepancies exist between an examinee's estimated and true [theta] levels, nonoptimal item selection is a likely result. Nevertheless, examinee response behavior consistent with…

A pilot study was conducted on test item ambiguity in standardized tests. A group of second and third grade children were selected and given a random sample of items from four standardized test series. Items were drawn from the reading, science and social studies subtests and put together in a composite reading comprehension, science, and social…

The desirable characteristics of criterion referenced test items and sets of items are described. A two-stage item tryout and item selection procedure are also described. The paper presents the results of using the procedure as compared with traditional item selection procedures used in selecting items for norm referenced tests. It was found that…

This study examined characteristics of multiple-choice reading comprehension tasks suspected of influencing their difficulty, through administration of the California Achievement Tests to 158 deaf college students. Problem components evaluated included manifest content, psychologically salient features, and processing demands. Variation in item…

The passage dependence of an item refers to the degree to which it is necessary to read the associated passage in order to be able to answer that item correctly. This paper studies the value of obtaining data about passage dependence in the construction of reading comprehension achievement tests. Passage dependence indices were examined in several…

Standard procedures for estimating item parameters in Item Response Theory models make no use of auxiliary information about test items, such as their format or content, or the skills they require for solution. This paper describes a framework for exploiting this information, thereby enhancing the precision and stability of item parameter…

Arguments which suggest that improved prediction of multiple criteria can be achieved employing pattern scoring of responses, as opposed to conventional methods, are examined. Models for improving prediction of single and multiple criteria were examined. The findings are: (1) simple linear combinations of predictor variables perform as well…

This paper considers the question of bias in group administered academic achievement tests, bias which is inherent in the instruments themselves. A body of data on the test of performance of three disadvantaged minority groups--northern, urban black; southern, rural black; and, southwestern, Mexican-Americans--as tryout samples in contrast to…

The content of selected major achievement tests is examined for bias in the frequency of references to the male and the female sex. The performance of males and females is contrasted on each item considered, and the relationships between item content and the performance differences is surveyed. The tests used in this study include the Metropolitan…

This study investigates whether a linear factor analytic method commonly used to evaluate violation of the item response theory (IRT) unidimensionality assumption is sensitive to measurable curricular differences within a school district and to examine the possibility of differential item performance for groups of students receiving different…

The extent, causes, and importance of context effects on item parameters for one- and three-parameter latent-trait models were examined. Items were taken from the California Achievement Tests Reading Comprehension and Mathematics Concepts and Applications subtests. The reading items were administered to 1,678 fourth-grade students, and the…

Two chi square techniques were applied to identify culturally biased items on the Reading Vocabulary and Reading Comprehension sections of the California Achievement Tests. Subjects were 1,035 Mexican Americans and 2,474 Anglo Americans in grade 7. Eight items appeared biased against Mexican Americans, but not Anglo Americans; seven occurred in…
