A study investigated the effects on the labor market of various proposed retirement options for teachers in South Carolina. First, questionnaires were sent to personnel officers in the 91 South Carolina school districts eliciting, first, facts and estimates relating to the supply of and demand for teachers and, second, their opinions on the ways in which the various retirement options would affect the teacher labor market in the state. Next, questionnaires were sent to 5,402 teachers to gather information on the labor supply. Twenty-two tables show data from the questionnaires. The first questionnaire (of personnel officers), with a 51% return rate, provided information on the following: (1) vacancies, applicants, offers, and hires; (2) teacher shortage areas; and (3) expected labor supply effects of seven new retirement options. The teachers' questionnaire, with 75% return rate, yielded information on teachers' retirement plans. Included are tables showing the number and percentage of South Carolina public school teachers who plan to leave public school teaching prior to retirement, along with percentage data on their planned activities, number of years prior to retirement, and responses to various new retirement system options. Seven major conclusions were drawn from the study, suggesting that early retirement options will have a very modest effect on the labor supply, but that improved fringe benefits might make the South Carolina public school system more attractive to potential employees.
