This is a very difficult question to answer. First of all, most universities take the position that it is best for their graduates not to be hired on the faculty. This is because too much “inbreeding” is antithetical to what universities value. However, most every school makes exceptions to this policy depending on the talents and skills of unusually gifted individuals. If you would like to be hired by the College of Social Work after graduation, you must have accomplishments that far exceed those of others in the applicant pool so that you not only stand out but also demonstrate to the faculty the exceptional scholarly successes you bring over the other candidates. Some schools have an informal policy that their own graduates may return and be hired after obtaining tenure (and thus receiving an objective determination of the worth of their accomplishments) at another institution.
