The program grad assistants sent a "save the date" email notification about higher-ed specific preview days last week, which are in late March. I don't have anything beyond dates yet, but they said they'd follow up with more information once admissions decisions were released.
@higheredlife I got an email from the Grad Assistants for the program today saying admissions decisions would be sent the week of March 2 (suggesting March 3 as the likely date). Did you get it too?
