Regular decison timeline

I applied in early December to UW. Does UW wait and let all students know of acceptance/denial at the end of March or are decisions sent out at continually?

If it is like ED, emails will be sent out in one cluster starting on a Friday near the end of March over a few days.

^^^ Son’s guidance counselor confirmed this on Friday. The rep said this round will be mid to late March.

Seems like such a long wait yet!
