OCCUPATIONAL INFORMATION SERVICE IN GUIDANCE FOCUSES ON THE DIFFERING NEEDS OF HIGH SCHOOL STUDENTS FOR KNOWLEDGE OF OCCUPATIONS. OCCUPATIONAL INFORMATION IS DEFINED AS ACCURATE, UP-TO-DATE TREATMENT AND INTERPRETATION OF DATA IMPORTANT TO THE PROCESS OF OCCUPATIONAL SELECTION, PREPARATION, PLACEMENT, AND ADJUSTMENT. TO MEET THE NEED FOR SUCH INFORMATION, A WELL-ORGANIZED OCCUPATIONAL INFORMATION SERVICE SHOULD BE PLANNED AND IMPLEMENTED AND BECOME AN INTEGRAL PART OF THE SCHOOL CURRICULUM. ORGANIZATION OF THE COLLECTION OF MATERIAL AS A WHOLE, IN TERMS OF WORTH, FREQUENCY OF ITEMS, AND COVERAGE AND AUTHENTICITY SHOULD BE THE GUIDING PRINCIPLES RATHER THAN MERE ACCUMULATION. THIS PRESENTATION SETS FORTH AN INFORMATION SERVICE FOR STUDENTS AS WELL AS SUGGESTING SOURCES AND CRITERIA FOR EVALUATION OF INFORMATION. IT WAS RECOMMENDED THAT NEEDS OF USERS ARE BEST SERVED BY MATERIAL ORGANIZED AND FILED ACCORDING TO INTEREST AND ABILITY AREAS. AN OUTLINE FOR PREPARATION OF OCCUPATIONAL INFORMATION AND SUGGESTED METHODS AND TEACHING AIDS TO HELP STUDENTS UTILIZE IT IS INCLUDED. (JH)
