Based on the assumption that communication skills are a critical component of organizational effectiveness and "promotability," a study was conducted to investigate the perceptions supervisors have of their female employees' communication proficiency. In particular, comparisons were made between evaluations of supervisors on a variety of communication competencies and female employees' self-evaluations. Subjects were 61 female professionals and their 61 immediate supervisors, who completed a communication proficiency and training survey designed to determine present levels of communication proficiency and future training needs. Respondents were also asked for particular demographic information, which was used in computing their Managerial Achievement Quotients: the number of promotions received since initial employment with the organization and current age bracket. The results supported the importance of self and supervisor evaluation of communication competencies for organizational achievement. Specifically, female professionals whose supervisors evaluate highly their ability to motivate others and understand organizational problems are more likely to advance vertically in the organization than those not as highly evaluated. Likewise, female professionals who favorably evaluate their own ability to give directions and participate in groups are more likely to be high achievers. (HTH)
