Women are under-represented at all levels of the Princeton faculty (3.27%) and are most noticeably absent from the highest levels. Fifty-five percent of the men and 11.5% of the women are in the top two professorial ranks. Eighty percent of the men, in contrast to 40% of the women, hold regular faculty positions. The "visiting" faculty title was found to have a different, "inferior" meaning for women. Fourteen departments and two schools have no females on their regular teaching staffs; no women are to be found on the faculty in any of the natural sciences, mathematics, or in engineering and applied science, despite the numbers of women earning PhD's in these fields annually. One-quarter of the administrative staff are women, yet there are no women in the three highest ranks, and 65% are in the lowest rank. The rank which is a first step for men is given to women after long and faithful service. There is a strong tendency toward segregated male and female job classifications, with the women's jobs receiving lower pay, despite the fact that some require greater skills. The University is asked to take positive steps with regard to these matters. The history and philosophy of co-education at Princeton is reviewed. Data appear in tables accompanying the text. (LR)
