When you publish your week, you finalise the timetable you've drafted, locking in the dates and times for your activities as a teacher. If your settings are configured to notify guardians and students, they will both receive emails regarding the co-curricular activities. If adjustments to the schedule are necessary later, you can still make changes, and students and parents will be notified of any updates.
As an admin, you have the ability to schedule and publish all of your teachers' weeks by clicking ‘publish everyone’s week’.
