The MyED BC platform goes through a year end transition process each year. During that process (most of August) all user accounts are deactivated (during the first week of August).
This week we are setting up the district and creating the new school year within MyED for our district.
All STAFF user accounts will be activated on Monday August 28 (Parent accounts will be activated in September)
So in short, each year your STAFF account will be deactivated through August, and it will be activated one week prior to the start of school
Hope this helps.
