Holland's theory of vocational choice assumes that most persons can be categorized into six types in accordance with their personality attributes. These six types are: Realistic, Investigative, Social, Conventional, Enterprising and Artistic. From Holland's theory, a high degree of congruence between personality type and occupational choice is postulated. To examine such congruence and occupational stability rates, the data from Project TALENT is reviewed. The sample consisted of more than 31,000 high school seniors who responded to the followup survey conducted five years after their graduation. The occupational choices obtained at the two points in time were classified into one of the six occupational types, and constituted the data for this study. It was found that only 18.5% of the males and 26.2% of the females chose the same occupation on both occasions. The higher stability rate for females is accounted for by the 60.3% stability rate of girls planning to be housewives. These and other results are discussed. (SJL)
