This study explores the role played by self-efficacy in predicting employees' intentions to apply for promotion, and also to confirm its importance as a third independent determinant of intention within the theory of planned behavior. To this end, questionnaires were administered to 108 employees of an organization operating in the north of Ireland. Regression analyses not only provided strong support for the addition of self-efficacy to the variables contained within Ajzen & Fishbein's (1980) framework, but also highlighted its importance in the context of women. Indeed, for women, it helped to explain some 77% of the variance and produced the strongest relationship with the intention variable. For men, however, only 54% of the variance was explained, and some importance was also attributed to the normative component of the model.
