I decided to call HGSE admissions and the person on the phone was very nice.
"All interviews have been sent out via email (at the same time) and those are scheduled for the end of the month. There have been times in the past when we had to go back into the applicant pool, which is why we do not send everyone their admissions decisions until mid-March." I did not receive an interview email.
I did interview at UPenn last weekend for their EdD in Educational Leadership, though.
Fingers crossed for Penn.
