Are grad programs sending out acceptance/waitlist/rejection letters in waves?

[MacKenzie Maccaux]

I have heard people in my program get emails notifying them that they are accepted or waitlisted for UW-Madison's Speech Language Pathology Master's Program. However, I have not received a response back from the university. I attend here currently for my undergrad and believe I have a solid application. However, do you think they send out acceptances/waitlists before rejections? Are they sending decisions in waves? I am very confused on what to think (it is hard to not be anxious). I am also waiting to hear back from other grad programs in Wisconsin, however, I have not seen any decisions from those specific schools on here.
