I applied to Columbia's Teachers College (MA TESOL), UT-Austin's Foreign Language Department, Vanderbilt's Peabody (English Language Learners), Texas A&M, and UPenn.
i received an email this morning from teachers college telling me to log onto the online application. under the "Application for Admission" heading there was a subheading "Decision Status" where there was the link "Your application decision is now available online." I clicked on it and read the decision letter.
as someone else mentioned already, Penn makes decisions on a rolling basis (for their master's candidates). i submitted my application on 11/27/2011, but one of my recommenders didn't submit her LOR until 12/7/2011. and i received a decision on 1/5/2012. so...four weeks.
I've applied to master's programs to five schools: Penn, Columbia, Vanderbilt, UT-Austin, and Texas A&M. I've heard back from Penn, Columbia (just a couple of hours ago), and Vanderbilt. Good luck to all!
