The purpose of this study was to investigate the roles of culture and motivation in the occupational decisions of senior high school students attending private schools. A theoretical framework guided the study. A questionnaire was administered to 492 Grade 11 students attending a stratified random sample of six independent (private) schools located in the Sydney (Australia) metropolitan area. Structural equation modelling was performed on the data collected. The major findings of the study centre on a new model of vocational decision-making, which provides empirical support for relationships between cultural orientation variables, expectancy-value variables, and related constructs. The findings may be used to advise senior high school students making occupational decisions.
