This report of teacher supply and demand in Florida looks at measures of teacher shortages during the 1984-85 school year, compares the projected supply of teachers by subject field with the numbers needed during 1986-87, and then projects the demand for teachers through the end of the century. As seen in prior years, some fields showed a much higher percentage of positions not filled by certified personnel than others. Mathematics, science, foreign languages, and education for the emotionally handicapped had even higher percentages of teachers hired out-of-field during fall 1984 than the prior year. The long-range picture continues to indicate the likelihood that an impending serious teacher shortage will be one of the most important educational issues Florida will face over the next 15 years. The report estimates that during 1987-88 the state will need more than 8,000 additional teachers if out-of-field teachers are not included in the calculation, and about 12,000 teachers if they are. The most important factor in teacher supply and demand in Florida during the years beyond 1986 is the shift in the age distribution of the population. (JD)
