A brief description of the Ohio Vocational Interest Survey (OVIS) is presented. This instrument was designed to facilitate vocational exploration rather than prediction. In this criterion-referenced instrument, the OVIS items are brief descriptions of activities, designed to represent a certain occupational cluster and/or criterion. A scale score is interpreted as an individual's current index of interest in a particular area of work. The OVIS attempts to provide a rational method of vocational self-description. The resulting OVIS profile is interpreted mainly on an idiographic basis. High and low interests can be rank ordered, initial individual counseling approaches in terms of the relationship between measured and expressed interests can be indicated, and percentiles and stanines can be shown. It is felt that the OVIS has a definite counseling use. Its two main objectives are to facilitate career exploitation and vocational and educational decision-making. It is noted that the OVIS should be used in conjunction with other instruments. (JS)
