Statistical issues associated with the supply and demand of science and mathematics teachers are reviewed in this conference report of the Committee on National Statistics. The conference was held to generate a plan for a study that would make recommendations to improve the information, sources, statistics, and models used in estimating and projecting the supply and demand for precollege science and mathematics teachers. Consideration was also given to elementary and middle school conditions. Major topics addressed included: (1) concepts of a qualified teacher and related statistical problems; (2) models used by the National Center for Education; (3) data on supply and needed improvements; (4) data on demand and needed improvements; and (5) activities for a proposed study on supply and demand for precollege science and mathematics teachers. Activities selected as important were those that focused on: measurement of teacher quality; descriptions of the entry/exit/bumping system; development of teacher population profiles; assessment of existing national and state data resources on teacher supply and demand; evaluation of project models; and review of statistics from colleges of education. This report also contains listings of the conference's participants, agenda, and reference sources. (ML)
