Just received this from the University of Chicago (Social Work, PhD) I've blanked out all names.
Dear ______,
I am writing to let you know that you have been placed on a very short waiting list for the SSA PhD program. You will be receiving an official letter soon from ______ _____ in the admissions office.
The doctoral admissions committee saw many strengths in your application and is convinced that you are highly qualified to be a PhD student at SSA. ______ ____________, in particular, gave us an enthusiastic endorsement of your application. However, there was much competition this year from applicants with strong backgrounds in social work practice, policy, and research.
About half the time we are able to make admissions offers from the waiting list. I won’t know how likely that is this year until late March or early April. I would be happy to set up a meeting to talk with you, if you would find that helpful.
