For the six available sets of empirical data, the discrimination (slope) parameter of the logistic item characteristic curve was found to have a significant positive correlation over items with the difficulty (location) parameter. This unpleasant situation can be eliminated by a suitably chosen transformation of the ability scale. (Author/RC)

Deficiences in the field of psychological testing associated with the assessment of vocational aptitudes are considered. The rationale for a new approach designed to obviate these deficiences is given. A description of the procedures which provide for implementation of the new approach and the semi-automated Performance Assessment System (PAS) is…

This paper has shown the advantages of tailored testing over traditional methods, the need for latent trait theory in the application of tailored testing, and some of the results available to show the quality of estimates obtained by tailored testing procedures. Since the tailored testing procedures overcome many of the problems with traditional…

This study analyzed user manuals and technical supplements of 27 aptitude and achievement tests to determine whether disabled children were included in development of the tests' norms, items, reliability indices, and validity indices. Most test developers provided scant evidence that their tests were valid for use with disabled students. (JDD)

The research leading to the decisions to revise the Graduate Record Examination Aptitude Test (GRE) (beginning in October 1981) is reviewed. The issues discussed include the format of the test (the timing of each section and the number of sections, the content of the sections--especially the analytical section), the scoring procedure for the GRE,…

In the summer of 1996, the U.S. Armed Services will implement the computerized adaptive testing version of the Armed Services Vocational Aptitude Battery (CAT-ASVAB). When conversion is completed at the 65 targeted military entrance processing stations, about half the applicants will take this test version. This paper describes the efforts that…

A number of strategies are described for adapting ability test items to individual differences in ability levels of testees. Each strategy consists of a different set of rules for selecting the sequence of test items to be administered to a given testee. Advantages and disadvantages of each strategy are discussed, and research issues unique to the…

A 15-stage pyramidal test and a 40-item two-stage test were constructed and administered by computer to 111 college undergraduates. The two-stage test was found to utilize a smaller proportion of its potential score range than the pyramidal test. Score distributions for both tests were positively skewed but not significantly different from the…

Current testing and selection practices in schools and the workplace are examined to describe the experiences of handicapped people and to determine the extent to which testing is a barrier to the full participation of handicapped people in society. The Panel on Testing of Handicapped People dealt in depth with the legal and psychometric issues…

Examines the differences between norm-referenced tests (standardized assessments of intelligence, aptitude, achievement, and personality) and criterion-referenced tests. Until school districts improve their potential to develop meaningful criterion-referenced tests, norm-referenced tests will be the major yardstick for measuring student…

Linear and equipercentile equating conversions were developed for two forms of the Graduate Record Examinations (GRE) quantitative test and the verbal-plus-quantitative test. From a very large sample of students taking the GRE in October 1981, subpopulations were selected with respect to race, sex, field of study, and level of performance (defined…

Questionnaire results from l04 psychologists serving the blind and partially sighted indicated disagreement on the tests used and on the evaluation of these tests. Tests of all kinds from 45 publishers were rated, and appropriate ages and populations (blind, partially-sighted) were suggested. (CP)

An ongoing series of experiments has extended Rose's information processing approach to job performance assessment. Each study investigated cognitive tasks from the literature on memory, psycholinquistics, and visual information processing, for potential inclusion in the test battery. Each task was then evaluated against three criterion areas: (1)…

Focusing on the use of the Metropolitan Achievement Test (MAT) with Project Follow Through evaluations, this report represents an extended discussion of the appropriateness of standardized tests for evaluation and policy research. First, the development of the MAT and its roots in the Army Alpha intelligence test are described in detail. The next…

FOUR PAPERS WERE PRESENTED ON WORK DONE IN THE FIELD OF SELECTION OF OLDER WORKERS (OVER 45) FOR VOCATIONAL TRAINING. IN SOUTH BEND, INDIANA, A PROGRAM WAS DESIGNED FOR THE EDUCATIONAL REHABILITATION OF 100 HARD-CORE UNEMPLOYED WHOSE GATB SCORES DISQUALIFIED THEM FOR VOCATIONAL TRAINING. THE U.S. EMPLOYMENT SERVICE HAS UNDERTAKEN A PROGRAM OF…
