This paper aims to present the state of the art of radio program design. Because there are no easy formulas for designing effective educational programs, the paper should serve to stimulate the creative powers of its users. The users I have in mind are all those involved (or potentially involved) in the design and production of educational radio programming. These could include subject matter specialists, development planners, scriptwriters, studio directors, and the generalists we call "radio producers." Anyone who makes decisions about the form and content of radio programs should find something of value here.
