Delayed Openings

In the event of inclement weather, WIS will make its own decision regarding a closure or delay. There will not be a specific announcement about WIS on local radio or TV stations. WIS posts delay/closure information on the website home page, tweets the decision (@WISRedDevils), posts a push notification on the WIS app, and includes an announcement on the WISE Line (202) 298-9473, typically before 6:30 AM.

In the event of an one-hour delay, beginning-of-the-day schedules move back by one hour; if there is a two-hour delay, beginning-of-the-day schedules move back by two hours. Unless otherwise specified, all standard dismissal times remain unchanged on delayed-opening days

Early Dismissal

If the school decides an early closure is necessary, an email is sent to all parents and an announcement is placed on the WIS website (parents may also sign up to receive a text alert). Detailed information regarding student pick-up and after school programs is included in the email.
