The Ohio Vocational Interest Survey (OVIS) has two aims: (1) to assist youth in understanding themselves in relation to the world of work and, (2) as a result, to provide a background for career choice. To do so, OVIS provides a functional system for relating an individual's interests into broad homogeneous clusters of jobs. OVIS consists of a six-item Student Information Questionnaire and a 280-item Interest Inventory, and is appropriate for use at the eighth grade level and above. A unique value of OVIS lies in its compatability with the following occupational information and guidance tools: (1) Directory of Occupational Titles, (2) The Occupational Outlook Handbook, (3) National and state labor market and occupational information publications and (4) the General Aptitude Test Battery. It is concluded that OVIS is an important tool for school guidance and counseling programs. (LS)
