ESTIMATES OF TEACHER SUPPLY AND DEMAND IN CALIFORNIA ELEMENTARY AND SECONDARY SCHOOLS LEAD TO THE EXPECTATION OF AN AVERAGE ANNUAL DEFICIT OF 6,510 TEACHERS DURING THE 1965-75 PERIOD. THE DEFICIT (31 PERCENT OF THE DEMAND) WILL HAVE TO BE MET BY OUT-OF-STATE RECRUITING AND BY HIRING THOSE WHO DO NOT QUALIFY FOR REGULAR CREDENTIALS. MAJOR REDUCTIONS IN PROVISIONALLY CERTIFICATED PERSONS AND IN PUPIL-TEACHER RATIOS ARE UNLIKELY IN THE NEAR FUTURE. AT THE JUNIOR COLLEGE LEVEL, THE SUPPLY OF TEACHERS DURING THE 1965-75 PERIOD IS DIFFICULT TO PREDICT, ALTHOUGH DEMAND IS ESTIMATED AT 1,750 PERSONS ANNUALLY. ALSO DISCUSSED ARE THE EFFECTS ON TEACHER SUPPLY AND DEMAND OF CHANGES IN CERTIFICATION REQUIREMENTS, FEDERAL SUPPORT, LEGISLATIVE ACTION, COMPETITION FOR PERSONNEL FROM HIGHER EDUCATION AND BUSINESS, LEVEL OF FINANCIAL SUPPORT, LONG-RANGE RECRUITMENT PROGRAMS, NEW INSTRUCTIONAL MEDIA, AND ATTITUDES OF COLLEGE STAFFS TOWARD TEACHER EDUCATION.
