The purposes of this research were to determine (1) the extent to which faculty are employed by the types of institutions from which they earned their doctorates in the United States, (2) the extent to which faculty have higher professional rank at employing institutions tat are the same type of institutions as those from which they earned their doctorates, (3) the extent to which female faculty are employed by the types of institutions from which they earned their doctorates, (4) the extent to which female faculty have higher professional rank at employing institutions that are the same type of institutions as those from which they received their doctorates, and (5) the extent of variability across academic disciplines in which faculty are employed by types of institutions from which they earned their doctorates. An exhaustive review of the literature on academic lineage was used to develop this research. All stratified random sample of 260 institutions from 2,873 colleges and universities was selected by Carnegie Foundation classification categories. Institutions were selected at random until the number of faculty members in each category corresponded to the estimated national distribution of faculty across Carnegie classification categories (n=3,940). The analyses revealed that the majority of faculty (74%) employed at all types of higher education institutions obtained their doctoral degrees fromresearch I institutions. Professional academic rank is an interaction between doctoral-granting institution and employing institution combined with gender. Male faculty are following the traditional "trickle down" theory of academic lineage while women faculty appear to be charting a different career path. Another unique finding was that there was not significant variability in the findings across academic disciplines. Academic success is a complex phenomenon that is not singularly explainable by academic lineage. As more women are entering into the academic ranks of higher education, changes in academic lineage are beginning to appear. The inflexibility and segmentation discussed in previous research is undergoing subtle but statistically noticeable modifications.
