This study examined the person-environment fit-career outcome relation by observing interests, self-efficacy and parental support as person aspects and major and occupational choice as separate indicators of the environment. Career certainty was selected as a career outcome. Two dimensional fit indices (People-Things and Data-Ideas) were examined as was the incremental validity of adding prestige fit indices. In addition, we examined the moderation of these PE fit-outcome relations by ethnicity (Anglos vs. Latino/a's). Results revealed that the PE fit predictors were moderately related and none of the two dimensional PE fit predictors significantly related to career certainty, while nearly all of the Prestige PE fit-certainty relations were significant. Support was found for the spherical structure of work types and person variables [Tracey, T. J. G., & Rounds, J. (1996b). "Contributions of the spherical representation of vocational interests."
