This study evaluated the guidance program of the Los Angeles City Adult Schools to determine if existing guidance services are adequately meeting clientele needs. Criteria obtained from the literature were submitted to a panel of consultants, who used a rating scale to identify significant criteria. An appraisal instrument was devised and refined; information was then gathered in structured interviews with principals, vice-principals, and counselors at 27 adult schools, and by scrutiny of their facilities and files. Significant findings included the predominance of educational over vocational counseling; extremely limited information services; inadequate data on students' personal, social, and mental status; little attention to student vocational interests, aptitudes, preferences, personality, out-of-school activities, or work experience; the expenditure of much working time on routine clerical duties because of personnel shortages; lack of suitable training and experience among about half the guidance counselors; and poor provision for followup services. Recommendations dealt with testing, vocational guidance, and the need for guidance-minded faculty and administrators. (Eleven tables and 94 references are included.) (author/ly)
