[Latest date of a decison]

Just curious about how close to the deadline some schools send decisions. What's the latest you all have received word from a school?

[do Psychology MA programs abide by April 15 deadline?]

If it's a master's program, do they have to give decisions by April 15th as well? I might consider this MA school if I get in, but not if I have to reply to the PhD offer before I even get an offer at the MA school. Does anyone know whether MA programs are held to the same deadline? I called the school, but they were generally unhelpful and seemed to have no clue that an April 15 deadline even existed.
