i called ptcas a few moments ago to ask about the different statuses that are set next to the schools designated. if the status of designations are set to "new", this means that the school is able to access them online but have not looked at them. if it is set to incomplete, then they have looked at the application but have not taken any action. and if they are set to complete, a decision has been made. i asked the ptcas representative if the status changed from "not mailed" to one of those three meant that it had been mailed out and he said that that was correct. hope this helps!
