How do we find out when schools will be announcing acceptances or denials for EA applications.
Schools usually list dates on their websites. Often, these are the last day for a decision and they may come out a few days earlier, in which case they usually email applicants, announce on social media etc to alert people of the new date.
Random example https://www.fordham.edu/info/20531/apply/2528/dates_and_deadlines scroll down to “plans and deadlines”, you’ll see the table includes decision dates.
