The adverse impact of a content-valid job sample test of metal trades skills was compared to that of a well-constructed content-valid written achievement test for the same technical area. The adverse impact of the former was considerably less. Suggests that industrial psychologists should explore more fully the potential of performance testing.…

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.…

A three-year research effort was conducted to design a crime laboratory proficiency testing program encompassing the United States. The objectives were to: (1) determine the feasibility of preparation and distribution of different classes of physical evidence; (2) assess the accuracy of criminalistics laboratories in the processing of selected…

Simulated crime scenarios, a mock crime scene, and five checklists of necessary skills (i.e., ability to summarize and communicate facts, identify inconsistencies, and determine the next…

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…

This packet contains a manual and a workbook for developing performance tests in vocational education. The manual gives an in-depth description of how to develop, score, and use performance tests. It includes the following sections: definitions of performance testing, steps in developing a performance test, selecting a performance development…

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…

This document contains a project report and procedures manual from a project in which a group of junior colleges and postsecondary technical schools in Texas developed, pilot tested, and disseminated performance criterion-referenced occupational examinations for technical occupations. The report describes how teachers and industry personnel…

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…
