Finding few differences between male and female leaders, the article suggests the use of a framework based on Schein's (68) career stages for further analysis of the sex structuring phenomenon.Aside from discrimination and social responsibility issues inherent in the relatively small number of women in managerial positions, the sex structuring of organizations constitutes a ubiquitous phenomenon in need of explanation by organizational researchers (1, 44). Why is a particular group excluded from some types of organizational positions, but not from others? How does it happen that even in organizations with large numbers of a particular group at the lower levels, few members of that group are found at the top?

Under this assumption, the processes of the organization may be viewed as performing a vital and desirable function in presumably channeling individuals to positions for which they are best suited. Hence, if it were found that women make less capable leaders than men, such information could form the basis for a relatively parsimonious explanation of the sex structuring of organizations. If such differences were not found, then other explanations for sex structuring must be sought. Data in the form of opinion surveys already indicate the existence of some beliefs that women make inferior administrative leaders (10, 12, 22). In addition, recent research shows that there are vast differences in the perceived character- 805
