Holland's theory of vocational preferences provides a powerful framework for studying students' college experiences. A basic proposition of Holland's theory is that individuals actively seek out and select environments that are congruent with their personality types. Although studies consistently support the self-selection proposition, they have not examined the processes underlying students' selections. It seems reasonable to presume that many students select academic majors because they believe or expect that the academic environments will be congruent with their personalities. Using data from 631 entering students, this research examined the possibility that self-selection is related to students' college expectations. Results provided support for the role of expectations in the selection of academic majors.
