This project was designed to collect information on the types of skills common to the appliance repair, refrigeration, and air conditioning service areas. A single task inventory was constructed from available course materials, revised by consultants, and administered to a random sample of 30 incumbent workers in each of the two service areas in two counties of Arizona. Completed task inventory forms were analyzed by computer with the tasks ranked according to percent of sample performing each task and time spent by workers performing each task. A report of the analyzed data was distributed to teachers in Arizona to be used as a basis for curriculum revision. This report defines the problem area and describes the goals and objectives, procedures, design and methodology, selection of sample, administration of inventory, and data analysis. Tables provide information about distribution of respondents by job title and years of experience, mean years of experience in service area by job title, and frequency of responses to the question of where training was received by service area. Also included are the task inventory instrument and the task analysis which indicates percentage of respondents performing task and time spent ratings. (NJ)
