This paper provides school building principals, teachers, and counselors with a systematic approach for implementing a comprehensive career education program at the building level by organizing teams of multi-discipline and/or multi-professional roles, called Career Activities Teams (CATs), composed of two or more persons committed to integrating career education concepts and activities into the educational program. Two main functions of key CAT personnel are identified: (1) to prepare for program installation and (2) to implement the program. These two functions are expanded in this paper along with a detailed description of the eight interdependent and interrelated functions of the CAT System: (1) develop career activity teams, (2) assess present levels of career education performance, (3) specify career education goals/objectives, (4) plan career education program activities, (5) implement career education activities, (6) monitor career education activity outcomes, (7) maintain performance levels, and (8) maintain career activities reference system. A flow chart and outline of the CAT System and references are appended. (TA)
