In this paper, a general conceptual framework for the role of consultant in the Bureau of Program Development and Diffusion as an education extension agent is presented. The key elements of the definition are (1) service, (2) local school system advocacy, and (3) developmental leadership. The operational definitions for each are viewed as relatively fixed. However, each consultant, through future inservice training and considerable introspection, will elaborate his own day-to-day style. In the final analysis, there is no set role definition applicable to every consultant. Each consultant must, therefore, operationalize his own role. (Author)
