Resulting in part from a project designed to identify and describe comprehensive programs of excellence in career education, this booklet is the eighth in a series describing current, successful career education practices. A successful career education program is dependent upon professional development. Based on this premise, the monograph: (1) describes the stages which educators need to consider concerning professional development for career education, (2) examines the specific roles and responsibilities of educators within the system, particularly the role played by the classroom teacher, (3) suggests training and retraining opportunities for teachers, (4) discusses involving teachers in the mechanics and organization of a professional development program, and (5) discusses activities that require involvement of all teachers, including assessing needs, designing curriculum materials, determining implementation strategies, and participating in evaluation and job placement. Other booklets in this series are available as VT 020 082-VT 020 090 in this issue. (SB)
