How can I specify class main teacher?

class teacher

For each class you can specify so called "class main teacher", who is responsible for the class during the school year. This teacher usually deals with e.g. students attendance, organizes class school's trips, parents meetings, and so on...
Note:
- this option is not meant as "all teachers in the class", the main "class teacher" is usually just one person,
- teachers names will be displayed in the top-right corner of class's timetable.

You can link the class teachers with their classes from the dialog "Class":

or from the dialog "Teacher":
