This report reviews eleven departments, accounting for 90% of the faculty women, in the Yale College and Graduate School. The most significant finding is the absence of women from the faculty, significantly less than other prestigious institutions. Many departments have no women on the professorial ladder. Women are concentrated in the lower ranks--23% of the lecturers and 30% of the instructors, while only 4% of the laddered faculty. There is also a preponderance of women in research positions, which are marginal compared to ladder faculty. Data indicate that although Yale trains significant numbers of women (21% of PhD's awarded), it does not consider them qualified applicants for Yale positions. This is true even in departments who display a tendency to hire their own PhD's. Other labor sources explored also revealed pools of qualified women from which Yale could have recruited. The authors therefore concluded that Yale has discriminated against women solely on the basis of sex. They urge the University to recognize the achievements of women as equal to men, and to take advantage of the resources of eminently qualified women academics. Supporting data appear in accompanying appendices. (LR)
