The Occupational Analysis of the Training in Industry project was designed to provide valid and reliable information on the work of trainers. To structure the research, the Task Inventory/Comprehensive Occupational Data Analysis Programs (CODAP) method of analysis was used. A central feature of this methodology was the development and use of a work of trainers task inventory in which training and development personnel were asked to indicate which training tasks they perform in their work, indicate the relative time they spend on each task, and provide relevant personal and organizational background information. The inventory contained 5 roles and 14 duties under which 131 tasks were organized. CODAP computer programs were used to organized. CODAP computer programs were used to compile composite job descriptions of the whole sample of trainers and selected subgroups in two forms: the duty job description and the task job description. A job clustering program was used to identify and describe the variety of job types existing within the training and development occupations. Six job types were identified. Three were classified at the managerial level, and three were classified at the officer or nonmanagerial level. A career path was identified, and the responsibilities and prerequisite job experience at each level were determined. (YLB)
