An experimental test battery designed to measure several perceptual abilities was administered to 1,368 (51.8% male) paying clients of the Johnson O'Connor Research Foundation (JOCRF) in an effort to identify and measure three perceptual abilities: (1) flexibility of closure; (2) speed of closure; and (3) spatial scanning. Subjects, who ranged in…

Addresses problems involved in developing and using performance tests, creating job-like testing situations, specifying measurable criteria, and controlling external factors to reduce problems of test reliability. Placing trainees in on-the-job training environments when training cannot be provided in the classroom or laboratory is recommended.…

The use of a performance-based assessment of senior medical students' clinical skills utilizing standardized patients was evaluated, with 6,804 student-patient encounters involving 405 students over 6 years. Results provide evidence for test security, content validity, construct validity, reliability, and test ability to discriminate a wide range…

A study examined the underlying factor structure of the aptitude tests and work samples being completed by students with educational disadvantages (limited reading and mathematics skills) who were assessed with the current assessment model in the Akron (Ohio) Public Schools. The amount of variance accounted for by the factors was also…

This report describes the development of a criterion-referenced proficiency examination for dental auxiliaries that consists of both written and performance tests in each of five areas: chairside assisting, patient education, diagnostic aids, therapeutics, and laboratory procedures. The content outlines of the tests are presented. The formation of…

Locally developed occupational tests were administered to 16- and 17-year-olds in a government-sponsored vocational education program in the United Kingdom over a six-month period in 1984. Job skills were tested in two occupational areas: use of a micrometer and invoice completion. Some performance tests were designed by researchers and some by…

In the domain of performance assessment, the errors-and-omissions (EOT) test falls between a work-sample test and a simulation test. The examinee works with a sample of material from the work environment. The correct answers and the exact criteria for acceptable performance are known in advance. For this study, EOTs were used for assessing entry…

The Micro-TOWER System of Vocational Evaluation was developed in response to the need for a revision of the TOWER (Testing, Orientation, and Work Evaluation in Rehabilitation) System. The Micro-TOWER system of work sample tests measures the major aptitudes required for most semi-skilled and unskilled occupations. It may be used as a screening…

These conference proceedings contain statements from those concerned with various aspects of research on job performance measures. Following introductory remarks, the formal presentations of work and ideas include "Air Training Command Interest in the Criterion Problem," by Donald E. Meyer, "The Criterion Problem: A Personnel…
