Latent trait theory is used as a basis for a definition of item bias, and an experiment is described in which a test of vocabulary items was not found to be biased when administered to two groups of high school students, one group of 58 black students and the other 168 white students. The experiment for the detection of bias began with separate…

This equating study of the National Board of Medical Examiners Examinations was a combined common persons and common items equating, using the Rasch model. The 1,000-item test was administered to about 3,000 second-year medical students in seven equal-length subtests: anatomy, physiology, biochemistry, pathology, microbiology, pharmacology, and…

Differences among test item writers and among different rules for writing multiple choice items were investigated. Items testing comprehension of a prose passage were varied according to five factors: (1) information density of the passage; (2) item writer; (3) deletion of nouns, as opposed to adjectives, from the sentence in order to construct…

A sixth-grade mathematics test was evaluated in two different ways, and the evaluations were compared. One method of evaluation was to use the Rasch model for item analysis and to accept or reject items on the basis of the extent to which the data fit the model. The other method of evaluation was to ask school superintendents and teachers to rate…

The Mathematics Achievement Test Project (MATP) was set up by the Learning Assessment Branch of the Ministry of Education of British Columbia to develop testing materials to assist teachers throughout the province in the task of evaluating students' performance in mathematics. The two major objectives of the project were to construct "banks" of…

Since grade-appropriate levels of standardized achievement tests must frequently be used in Elementary and Secondary Education Act Title I evaluations, there may be large discrepancies between test difficulty and the achievement level of those being tested, with resultant inaccuracies in the scores. Procedures based on the Rasch scaling model were…

This study is an initial investigation of the effects of grade level, item content and type of probe on children's understanding of communicative ineptness. It was hypothesized that children's recognition and avoidance of inept communications would increase as a function of age and that recognition of ineptness would precede the ability to avoid…

The Regents Competency Testing Program has been designed to assure that all students develop adequate skills in reading comprehension, writing, and mathematics before graduation from high school in New York. This bulletin provides information on two of the program's three basic elements that contribute to the accomplishment of this goal. First,…

These written domain referenced tests (DRTs) for the area of transportation/automotive mechanics test cognitive abilities or knowledge of theory. Introductory materials describe domain referenced testing and test development. Each multiple choice test includes a domain statement, describing the behavior and content of the domain, and a test item…

Using informal, objectives-based, or linguistic methods, three elementary school teachers and three experienced item writers developed criterion-referenced pretests-posttests to accompany a prose passage. Item difficulites were tabulated on the responses of 364 elementary students. The informal-subjective method, used by many achievement test…

Three kinds of rating statements, trait-oriented, worker-oriented, and task-oriented were evaluated in a context permitting the comparisons to be made in terms of criteria external to the ratings. One hundred twenty Air Force noncommissioned officers assigned to seminar grouPs of 13 or 14 were involved. No evidence of superiority was found for any…

Sample test questions are given for the Proficiency Testing Program adopted by the Idaho State Department of Education. Except for the writing skills test item, which requires a writing sample, all questions are objective, multiple choice items. Sample questions are given for reading, spelling, and mathematics. (MH)

A general process for testing the feasibility of applying alternative mathematical or statistical models to the solution of a practical problem is presented and flowcharted. The system is used to compare five models for test equating: (1) anchor test equating using classical test theory; (2) anchor test equating using the one-parameter logistic…

Three paradigms for assessing children's vocabulary knowledge were evaluated in this study: synonym, synonym in context, and cloze. The vocabulary tests, a paper-and-pencil adaptation of the on-line tests used in two previous studies, were administered to 830 second through seventh grade students. Subjects performed similarly on the three formats…

Latent trait models may offer considerable potential for the improvement of educational measurement practices, but until recently, they have received only limited attention from measurement specialists. This paper provides a brief introduction to latent trait models, and provides test practitioners with a non-technical introduction to the…
