Abstract: The near 70-year studies on the structure of vocational interest richened and developed the theories, mainly including the following: Roe’s circular model, Holland’s hexagonal model, Prediger’s dimensional model, Gati’s hierarchical model, and Tracey-Rounds’ spherical model. Some studies evaluating the fit of various models to the data were organized, and they indicated that Holland’s model was more suitable for the U.S. samples (non-ethnic samples), while the other models needed further evaluation. The studies also suggested that no widely applicable model existed, and so cross-cultural studies on vocational interests would continue to be made and deeply validated.

Key words: vocational interest, the structure of vocational interests, the types of vocational interests
