Statewide minimum competency testing programs have emphasized basic skills in reading, mathematics, and writing. However, continuing concerns are expressed in national reports about the level of achievement, particularly in mathematics and science, and increased testing has been suggested as a means of encouraging curriculum change and evaluating…

In response to concerns raised by principals at both the elementary and intermediate levels regarding the amount of instructional time consumed by students taking tests which were not related to day-to-day instruction, a study was conducted of the amount of time spent preparing to give such tests and actually administering them, and the manner in…

To date, the majority of computerized adaptive testing (CAT) systems for achievement and aptitude testing have been based on the dichotomous item response models. However, current research with polychotomous model-based CATs is yielding promising results. This study extends previous work on nominal response model-based CAT (NR CAT) and compares…

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--written for school administrators, teachers, counselors, parents, and the community--describes educational tests and measurements and test-related statistics. While specifically intended to help readers interpret the tests administered in the Los Angeles (California) Unified School District, this information may also be used to…

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…

Examines some of the problems in interpreting data from attitude measures when the dimensionality of the instrument and sources of heterogeneity in the population are ignored. Illustrates this point by describing the development of an instrument designed to measure children's attitude toward science-related activities. (TW)

Stanford Achievement Test scores of 1,434 elementary-level students already placed in either regular or special education programs were arranged according to four cutoff points: 20th, 15th, 10th, and 5th percentiles. This identification method, setting the cutoff at the 5 percent level, is proposed as a preliminary screening device for special…

State legislative action to control and reward teaching quality has resulted in the coming of age of systematic teacher performance evaluation for certification, merit pay, or career ladder advancement decisions. This article overviews issues of credibility and practicality--including test design, validity, and reliability--which arise when…

The initial development of a testlet-based algebra test was previously reported (Wainer and Lewis, 1990). This account provides the details of this excursion into the use of hierarchical testlets and validity-based scoring. A pretest of two 15-item hierarchical testlets was carried out in which examinees' performance on a 4-item subset of each…

This paper provides an overview of the types of testing accommodations used for students with disabilities and presents arguments for and against their use. It begins by discussing student participation in educational assessments and federal requirements concerning the participation of students with disabilities. The types of accommodations are…

Second language (L2) computer-adaptive testing (CAT) is a technologically advanced method of assessment in which the computer selects and presents test items to examinees according to the estimated level of the examinee's language ability. The basic notion of an adaptive test is to mimic automatically what a wise examiner would normally do.…

Several methodological problems (particularly the assumed bipolarity of scales, instructions regarding use of the midpoint, and concept-scale interaction) which may contribute to a lack of precision in the semantic differential technique were investigated. Results generally supported the use of the semantic differential. (Author/JKS)

Implementing measurement specialists' ideas about content validity with licensure examinations and the problem of court litigation are discussed. Validity issues surfacing when sponsors of national licensure examinations conduct validity investigations are considered. Issues include local versus national focus on content validity, job analysis,…
