This handbook was designed to assist vocational personnel in assessing professional development needs and developing an individual growth plan. It contains five sections: (1) An Overview of Staff Development, (2) What is a Need?, (3) Assessing Needs: Alternative Methods, (4) Planning and Evaluation Activities, and (5) Facilitation Suggestions. Questions of rationale and responsibility for staff development and inservice education are discussed in section 1. Section 2 provides a framework for categorizing improvement and growth needs in relation to licensure requirements, institutional requirements, and individual expectations. After identifying potential resources which can be used to assess needs and providing guidelines for selecting appropriate needs assessment methods, section 3 presents six methods including their advantages and disadvantages. Basic steps identified in section 4 for planning professional development include prioritizing needs, selecting inservice activities, and evaluating progress. Specific actions and activities to facilitate the continued professional development of teachers are listed in section 5 in separate categories of suggestions for teachers, vocational administrators, vocational relicensure committees, teacher educators, and state department personnel.
