This study examined Holland's theoretical proposition, that personality-work environment congruence influences career stability and change, with a sample of 212 career changers (respondents who expressed an intent to change career and had engaged in preliminary career change activity) and 249 career persisters (respondents who indicated an intent to remain in their current career). Independent groups ANCOVA (controlling for age and current career tenure) indicated that career persisters scored higher on congruence than career changers, however, the effect size was within the small to medium range. Repeated-measures ANCOVA indicated, with a medium effect size, that career changers moved towards careers that were more congruent with their personality profiles than their current careers. Practical and theoretical implications are discussed.
