Term timetable functions are generally used if the timetable is changed during the school year (e.g. at the end of the school half-year, when one or more teachers are absent for a considerable period etc.),
With a term timetable the school year is divided into several periods of time and a timetable can be created for each of these terms independently of each other. You could of course save each timetable in a separate file, but you would then have to accept a number of disadvantages. The term timetable offers the following advantages:
•You have a single file for the whole school year.
•Term and timetable changes can take place during the week.
•Cover planning always accesses the currently valid timetable automatically. Mistakes are impossible.
