No calls and 7 out of 21 of the school I applied have not taken up letters yet.
No calls for me so far, no emails either.
My impression is the following schools have called (based on comments here):
Loyola
Rhode Island
A few of the teaching schools called and did Facebook interviews as well.
Some candidates had 1-2 calls from last week. Most expected in the coming 2 weeks.
I have 3 calls so far from schools different than these two, and none is a "teaching school", but yes I would expect 90% still to make calls.
