A study examined the overall structure of Australia's engineering technical work force, the relationships between occupations in each branch and level of the engineering work force, and the job functions of each occupational cluster. The primary purpose of the study was to gather data to assist Technical and Further Education (TAFE) curriculum planners and planners working with other education and training bodies. The analysis was based on two national surveys. The first survey, which was intended to collect general information on the number of workers in each occupational level and branch of engineering, involved a net sample of 1,089 government and industry organizations and 1,090 TAFE and college of advanced education students. The second survey (of a net sample of 1,230 engineering technical workers from all of Australia's states and territories) examined workers' background characteristics and detailed each respondent's job functions. Cluster analysis sorts were carried out by using a statistical rather than a judgmental process, and a cluster diagram was developed after each sorting procedure. Ninety-nine primary clusters were identified. These primary clusters were merged into four major clusters given the following designations: engineering systems and administration (438 respondents), civil engineering and surveying (318 respondents), drafting and design (123 respondents), and electrical and electronic engineering (188 respondents). Job function profiles and background characteristics (including average age, salary, highest education, and proportion of females) were compiled for each cluster. (MN)
