I have changed my classes for the new year, but my reports show the old teachers?

This means you have not updated the Tutors area ready for the new year. 

To update this please pop to Admin > Config > Tutors

For any Teachers not currently assigned to a Form, click "Assign"

Then, simply chose Year Group and a Form for that Teacher and click update. 

If your Teacher is already assigned to a Form then click "Manage"

Then simply click "Unassign" to remove the current allocation. For the new allocation, choose it from the dropdown and click "Add New"
