This chapter on designing and implementing effective staff development programs is taken from a guide to instruction and services for students with disabilities. The chapter focuses on assessment of staff development needs and identification of priorities for training. Staff development options are discussed in terms of formats (such as workshops, summer institutes, videotape applications) and levels of training based on target audience. Planning staff development programs involves the following steps: identifying needs, considering the characteristics of adult learners, establishing goals and objectives, obtaining commitments, and designing the program. Extrinsic and intrinsic incentives are discussed. Methods for determining the effectiveness of the staff development program are noted. Appendixes include a needs assessment instrument, a list of characteristics of adult learners, and a staff development checklist. (Contains 37 references.) (JDD)
