This dissertation investigates the supply of and demand for High School teachers, working in prescribed faculty areas in Government schools in the A.C.T., over the period from January 1983 to July 1984, for all new temporary teachers appointed to the Service. Statistical details of vacancies for assistant teachers, in the 12 defined faculties of this study, were obtained from the Assistant Principals (Staffing) of the 17 A.C.T. High Schools, as well as from records maintained by the Staffing Officers of the A.C.T. Schools Office. The levels of High School teacher demand, for the period under investigation, are compared with similar statistics obtained for previous years in the A.C.T., as well with other Australian and international figures on teacher supply and demand. Through these comparisons, suggestions are made regarding emerging trends of teacher shortage, in particular faculty areas. Historical parallels are presented to supplement these arguments and to give underlying reasons for the projections that are made. The potential supply of faculty teachers over the period is investigated through an analysis of teacher faculty waiting lists. Numbers from these lists are compared with the actual demand statistics previously collected and a potential supply to vacancy ratio collected for each faculty area. A major part of the study is the construction of supply satisfaction indices, under the headings of: "Overall Satisfaction, Teaching Skills, Academic Qualifications, Other Requirements and Recruitment". These indices were derived from Likert type rating scales completed by the Assistant Principals, in respect of each of the 397 temporary teachers employed. After obtaining an average rating in each faculty, for the five measures of satisfaction, as determined by the Assistant Principals, observations are made as to how closely these indices match the corresponding potential supply indices. Particular emphasis is placed on the comparisons between the recruitment satisfaction index (i.e. - how quickly recruitment was expedited) and the potential supply ratio for each faculty. Reasons are advanced for any significant differences detected, and the overall findings interpreted in terms of possible future trends. The study concludes with an analysis of factors affecting the market for teachers. Recommendations are made for future planning that may offset problems which were detected in the A.C.T. market for High School teachers.
