This monograph, consisting of two papers, is intended to assist the teaching profession to analyze and study the broad picture of inservice education of teachers. In the first paper, a rationale for the present state of the art is given and also a projection for the future. Differing, but equally effective, approaches to the inservice education of teachers are analyzed. Factors that determine program purposes and characteristics are discussed. Scenarios of three illustrative inservice education programs are presented in detail. In the second paper, a number of basic conditions that need to be considered in planning for more viable inservice alternatives are considered, and suggestions on how some of these issues may be resolved are offered. The point is made that the "whys" and"hows" of inservice education will be understood more clearly if they are examined in relationship to foreseeable changes in the total approach to teacher education, and school conditions in general.
