California Career Centers are inschool information centers offering a variety of information and guidance which can be used efficiently and constructively by career guidance personnel as an educational tool to facilitate the career development of students. This study represents an effort to assist guidance personnel to implement, maintain, and improve career centers. Data was collected from a questionnaire given to career centers and students in participating schools. Each of the essential parts of an operational career center are discussed at length: (1) staff (career counselor, work experience coordinator, and paraprofessional), considered in relation to their background and training, job description and allocation of time, and student utilization of their services; (2) printed and audiovisual sources of career information; (3) career center programs and activities; (4) the effectiveness of career centers on students; (5) financial aspects of operating career centers; and (6) evaluation. Detailed suggestions are offered on ways to implement, maintain, and improve a center. Each chapter includes recommendations and references designed to furnish practical guidelines for career education personnel, and the document concludes with a general summary of recommendations. A list of participating schools and the instrument used in the study are appended. (Author/EC)
