Supply and demand of teachers in California

A model of input to and output from teaching in California showed the effects of the Teacher Preparatory Institutions (TPI's), the schools, and teachers themselves. The model was based on a reconnaissance, questionnaires addressed fo a 5% sample of teachers and their administrators, interviews at the TPI's, and questionnaires on career choice filled out by college students. By collating information from these sources, we estimated the extent of future shortages at the elementary and secondary levels, and adduced reasons for them. We recommended to the California State Board of Education a series of actions on the part of various responsible agencies to help relieve the expected teacher shortage.
