By default, the new starter wizard does not include the Teacher Details screen. However, as the teacher number is mandatory for the SWC, you may want to have this screen available when adding employees.
To add it:
Go to Setup, then Settings.
Click Field Settings.
Search Tab-PostEmployment-Employment_Teacher and click it.
Tick the Include box and click Save.
Search Tab-PostEmployment-Disable and click it.
Tick the Include box and click Save.
