This workshop presenter's guide is intended for use by administrators in training one another in the Project Leadership program developed by the Association of California School Administrators (ACSA). The purposes of the guide are: to provide administrators with a framework for deciding when others (particularly subordinates) should participate in the decision-making process; and to help administrators obtain high quality solutions to problems that are acceptable to subordinates, if acceptability of solutions is important for effective implementation. A case study method is used, whereby a problem is presented, and suggested discussion topics and participant activities are given. The problems are diagnosed keeping in mind the four alternative decision-making styles: (1) autocratic; (2) consultative; (3) group; and (4) delegated. Research evidence emphasizing the importance of effective decision-making is presented. Administrators are encouraged to promote participative decision-making in schools, but only in areas in which teachers will want input, relevance, expertise, and jurisdiction. The guide contains an 8-item reference list, 7 handouts, 10 masters of numbered transparencies for use in the sessions, and a suggested reading list. (AA)
