This research tested the theory that self-esteem acts as a moderating variable in the occupational choice process. The theory was not supported when the relationships between self-esteem, self-perceived abilities and abilities perceived as required in occupations were examined. Rather, the data were consistent with the self-implementation theory of vocational choice. However, it was found that those with high self-esteem were more likely than those with low self-esteem to see themselves as possessing the abilities they saw as necessary in their chosen occupations.
