This study investigated the effect of social class, race, and sex on the work values of ninth-grade students in a large metropolitan area. Measures of work values were obtained using Super's (1970) Work Values Inventory. Results indicated that race and sex have differential effects on the development of work values. Significant differences between black and white students appeared for the variables of associates, altruism, variety, and intellectual stimulation. Males and females varied on creativity and altruism. Where signficant differences appeared between blacks and whites, white students in all cases expressed greater value for each of the work value constructs. In general, black females of low social position scored low on the work values scales. (Author/RS)
