Go to 'School > Timetable > Timetable Administration > Timetable Settings > Staff names
Here you will view all teachers within a selected academic year and their names as will appear on timetables and registers. Teacher Identifiers are 3 character identifiers for each teacher at your school. The identifier appears on school, student and room timetables, to save space.
You are able to edit existing 3 character identifiers (they are automatically generated for each teacher), to set a maximum of 4 characters per teacher identifier. Just click on the teacher name whose identifier you want to change and you will see a new form appear that allows you to add a new identifier.
