This memo contains a comprehensive review of past, present, and likely future conditions related to the supply and demand situation of public school teachers. Primary emphasis is placed on the quantitative rather than the qualitative aspects of the teacher supply and demand picture. Section I summarizes and presents highlights of findings on: (1) supply of qualified teachers; (2) demand for public school teachers; (3) actual demand for new teachers; (4) personnel requirements for achieving minimum quality levels; (5) teacher supply compared to demand; and (6) outlook for teacher supply and demand in the 1980's. Section II contains detailed information, including tables, elaborating on, and pertaining to, the procedures, assumptions, sources, statistics, and limitations involved in developing the findings reported in the memo. Strong evidence is presented that the major key to solving the quantitative and qualitative problems of teacher supply and demand is to improve the attractiveness of teacher salaries and working conditions.
