A discussion of the objectives, breadth, and strategies of staff development for bilingual education program supervisors, teachers, teacher educators, and program developers outlines principles for assessing educational needs and planning development programs. Recent experience in bilingual program staff development focusing on language teaching methodology and multicultural curriculum development is reviewed, and the common content and task emphases of development programs for teachers, supervisors, and teacher educators at the university level are analyzed. Economic and other resource considerations are discussed, and a practical approach to staff development program planning that involves case study analysis is recommended. Examples of representative case studies are presented along with analysis questions and illustrations of the staff development needs and strategies derived from each case study. Training issues and concerns and suggested program directions for the future are summarized. (MSE)
