Schools will decide from the interested teachers which one they wish to make a formal offer to.  You will be notified on your Airsupply dashboard and by text when you receive a formal offer. You must accept any formal offer within 90 seconds  if the role starts within 24hrs, 1 hour if the role starts in between 24-48 hours and 6 hours if the role is more than 48 hours away, otherwise the offer will expire.
