A number of applied psychologists have suggested that trainability test Black-White ethnic group differences are low or relatively low (e.g., Siegel & Bergman, 1975), though data are scarce. Likewise, there are relatively few estimates of criterion-related validity for trainability tests predicting job performance (cf. Robertson & Downs,…

Work sampling is a managerial accounting technique which provides information about the efficiency of an operation. This analysis determines what tasks are being performed durinq a period of time to ascertain if time and effort are being allocated efficiently. (SK)

Compares three competence assessment strategies that differ in the forms and amounts of evidence required and process of obtaining it: (1) performance samples; (2) workplace observations; and (3) evidence of prior achievements. Concludes that performance evidence may need to be supplemented with prior observations or achievement records and that…

This paper describes the Work Performance Assessment (WPA) and the Work Personality Profile (WPP) and provides instructions for their use. The WPA and WPP evaluate behaviors associated with job retention and advancement among disabled workers. Together the two evaluation components form a comprehensive observational assessment designed to provide…

Describes miniature job training and evaluation situations administered to 1,034 "low aptitude" Navy recruits. Checklist criterion data describing the on-the-job performance of the sample were collected after the recruits were on their fleet assignments. The results confirmed the predictive validity of the miniature job training…

Using participant observation and in-depth interviewing, two vocational evaluation facilities, five professionals, and eight clients were studied. A variety of professional and organizational factors were found to be integral and contradictory parts of the assessment, affecting its character and outcome. (Author/SEW)

Work sampling is a research technique where workers are observed at random times and their activities recorded. Data are converted to percentages indicating the overall distribution of how time is spent in various categories. A background of work sampling, its history in libraries and the planning and implementation of a school library media study…

The Work Performance Assessment (WPA) is a brief work simulation designed to evaluate job maintenance skills, emphasizing work-related social/interpersonal skills rather than specific vocational skills. The WPA uses three work samples involving sorting of food service items to measure 19 common work demands in four categories: responding to…

Comparisons were made of three different procedures for rating job performance and the validity of each procedure was estimated. All three procedures were based on observation of videotaped presentations of 12 electrical measurement problems, 8 of which had errors associated with them. The three procedures involved the use of three different…

The purpose of this publication is to review each of the Vocational Evaluation and Work Adjustment Association sample testing standards as well as to provide insight and understanding into the underlying purposes of the guidelines. The first of three sections focuses on those standards designed to insure that a work sample actually measures what…

Tailored Response Testing (TRT) is a new type of test that has demonstrated its applicability to the evaluation of human performance in a wide variety of occupations and work settings. The Navy is using TRT to measure the technical proficiency of job incumbents in three of its jobs. The methodology holds great promise for testing aboard ships as…

The document presents a vocational evaluation process based on a diverse mixture of proven principles and practices that have been used in school-based vocational evaluation programs for handicapped students. Following a foreword (part 1), part 2 offers several definitions of vocational evaluation and vocational assessment. Part 3 compares…

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.…

Although predictive validation is the primary method of justifying a particular work sample for use as an assessment device, content validation is being recognized as an alternative strategy. Confusion exists over whether content validity should refer to the representativeness of the work sample, in terms of tasks to be performed, or behavioral…

Concerns expressed regarding the use of work sample systems for assessing handicapped students include: limitations of trait assessment; criteria and standards; application of work sample results; need to measure learning outcomes; and limited focus. Recommendations include use of competency analysis, selection criteria, and commercial and locally…
