Over a period of three years, the National Consortium for Humanizing Education worked with teachers and students in two states to test hypotheses drawn from a model in which student outcomes (including good mental health) were seen as the results of a learning process occurring between individuals rather than as the product of an institutionalized situation. In this model, mental health is assumed to be learned in much the same way that other capabilities are learned; that is, as the result of an interdependent interpersonal interactive process. The goal of the applied research program was to devise, demonstrate, and document Interpersonal Skills Training for Teachers. This summary document presents an overview of the total project, and discusses 15 basic studies. Conclusions from each of the studies indicate an over-all effectiveness of the Interpersonal Skills Training for Teachers. (Author/PC)
