On the basis of an established need, the Occupational Values Inventory (OVI) was developed as one of the data collection instruments for the Vocational Development Study to measure the occupational values held by ninth graders, including: (1) Interest and Satisfaction, (2) Advancement , (3) Salary, (4) Prestige, (5) Personal Goal, (6) Preparation and Ability, and (7) Security. The 35 items on the OVI consist of three statements or phrases representing three different values. The individual is forced to select the phrase or statement most important to him in selecting a job as well as the least important. Though restricted, investigations thus far indicate that the OVI reliably measures selected affective traits that uniquely contribute to distinctions between boys and girls, academic and vocational-technical students, and successful and unsuccessful students, and is a potentially useful guidance instrument. Measures of internal consistency, stability, and concurrent validities were utilized to establish reliability and validity of the OVI, and plans for predictive and construct validity studies have been made. Norms based on a sample of 548 ninth grade boys and 531 ninth grade girls are included, and a sample instrument and directions for administering and scoring the OVI are appended. (SB)
