The study was conducted to develop methods for using timely, firsthand occupational task information on automotive mechanics in order to identify critical performance requirements that warrant formal training. The methodology used is described in detail. A Task Inventory Questionnaire was completed by 18 auto mechanics and 12 supervisors in each of eight participating States. The questionnaire consisted of a checklist of 380 automotive repair tasks and 12 questions about the tasks which related to job relevance, task performance, and training criticalness. Background data were gathered from auto mechanics, supervisors, and State agencies supporting the study. Responses to the questionnaire indicated 59 of the 380 task statements were identified as not a part of the job of automotive mechanics. The survey results are discussed and presented in tabulated form. Over one-half of the document consists of appended materials which include: a list of participating State agencies and their key support personnel, background characteristics of respondents, a 99-page section containing nine tables of task inventroy data, and additional task statements.
