Highlights are presented from a third survey of educational services provided by public radio stations to elementary, secondary, and postsecondary educational institutions throughout the United States for the 2-year period from September 1, 1981 to August 30, 1983. Findings presented are based on the responses of 49 stations out of the 132 stations surveyed that indicated that they provided some level of educational services. Data broken down by educational level--K-12 and postsecondary--indicate the number of stations providing programming by type of station and by region; services provided; distribution of programming; and nonbroadcast distribution. Plans for educational services are summarized for national programming, children's programming, and greatest needs. Appendices contain a survey form with a tabulation of responses, and a description of the survey methodology. Also appended are reported public radio educational services by station, examples of innovative programming or services, and a summary of educational research and evaluation studies reported in the survey.
