This chapter is designed to aid in the understanding of trends toward developing more effective programs of selecting and preparing educational supervisors. A survey of present policies and procedures in the selection of personnel for supervisory positions shows that the selection process could be significantly improved simply by setting up and adhering to specific procedures and standards. An evaluation of certification requirements for supervisors points out the general lack of provisions to enforce professional ethics and standards. A description of trends in the education of supervisors covers such new programs as internship, specialist programs, continuing development programs, simulation training, inservice education, and sensitivity programs. A final section reviews research on leadership, showing its implications for the selection of supervisors. Predictions are made regarding future supervisor selection procedures. (TT)
