The report describes the results of a detailed occupational survey of the corrosion control career ladder. Responses to a 457-task, time rating inventory from 1,015 personnel (representing 64 percent of the career field) were analyzed to produce seven specific findings and the career ladder structure. The career ladder includes a variety of jobs performed by airmen in the prevention, identification, and control of corrosion on metal surfaces of aircarft, missiles, and support systems within the Air Force. Subject areas investigated include duties and tasks characteristically performed by corrosion control personnel at various stages in their careers from the standpoint of their career progression and time in service. Background data on the personnel, comparisons between field performance and items in the Specialty Training Standard, and a short discussion of the relative difficulty of tasks as rated by personnel of the career field are also contained in the report. Appended are summarized survey results for personnel in each job cluster and job type in the career ladder (number of members, major command, skill level, mean number of tasks performed, and primary duties).
