I applied to NYU's MA program in Higher Ed Admin as well and haven't heard anything back yet either. My guess is that if we don't hear anything this week, we're either waitlisted or rejected. Last year, it seems that they sent emails to invited candidates around Feb. 23rd, but the recruitment dates were late in March (26th-27th) compared to this year's (11th-12th). Let me know if you hear anything from them and I will do the same for you! The waiting is the hardest part!
