The Use of Worker Characteristics in Marine Corps Classification and Assignment.

摘要

This research was designed to explore the possibilities of acquiring greater benefit in the areas of Marine Corps classification and assignment by utilizing data collected on worker characteristics. Primary attention is given to measurements of physical demands and environmental conditions of jobs that are not readily measured by objective aptitude tests. Reviews are made of earlier data collection by the Marine Corps using task inventories, and to the research of other organizations in this area. Data are presented concerning the relationships among earlier worker characteristics data collected by task inventories and aptitude test results. The use of aptitude tests in the Marine Corps to select Marines for specialized training in service schools is analyzed. Statistical studies of test validities for selection of both Navy and Marine Corps enlisted personnel for service school attendance are described. An important part of this report is devoted to a discussion of Hanman's 'specific method' for appraising the physical and environmental demands of jobs and assessing the physical capacities of individuals to meet those demands. Instructions for use of the specific method are given in detail. Recommendations are made about personnel research, test validation, and methods of appraising worker characteristics in the Marine Corps. (Author)
