As part of the final report by the Arizona Board of Regents' Task Force on Excellence, Efficiency and Competitiveness, a discussion of the numbers available to predict teacher supply and projected student enrollment is presented with an examination of Arizona's professional education programs and how they are meeting the needs. A discussion of teacher supply and demand in the 1990's focuses on: retirement statistics; the projected need for teachers; the need for minority teachers; the effect of the Pre-Professional Skills Test examination; the need for teachers in rural Arizona; the need for teachers in specific disciplines; other routes to certification; post-baccalaureate programs; alternate certification; and data needs. Professional education of teachers in Arizona is presented as: the 5-year education program; pilot programs; additional classroom training; and the need for working partnerships. some of the conclusions are that the composition of the student body will change significantly, Arizona will have a continuing demand for teachers through the 1990's if the current teacher-student ratio is maintained, and experimentation and research on teaching and teacher preparation are needed. Six recommendations include: develop a program to recruit minorities into the teaching profession; develop pilot programs in such areas as beginning teacher induction and delivery of education in remote areas; and develop standards that make the colleges of education accountable for the performances of their graduates.
