Codes

(M) Main subject

Check this box to categorise a subject as a main subject. For further details please refer to chapter ' User tips / Main subjects '.

(F) Fringe period

Use this option to categorise a subject as a fringe period subject. The attribute ensures that lessons of this subject are scheduled preferentially at the beginning or the end of a school day or half-day (depending on the grid). For further details please refer to chapter ' User tips / Free periods and fringe periods '

(O) Optional subject

This option allows you to categorise a subject as an optional (non-compulsory) subject. The attribute ensures that lessons of this subject are scheduled preferentially at the beginning or the end of a school day or half-day (depending on the grid). For further details please refer to chapter ' User tips / Free periods and fringe periods '

(2) More than once a day

This option should only be used in special circumstances. If it is active, the optimisation algorithm can schedule the subject at entirely irregular intervals and even several times a day. Checking this box deactivates the weighting settings for ' The same subject cannot be taught more than once on the same day ' and ' Avoid errors with double periods '.

(G) Not a fringe period

Selecting this option causes the software to schedule lessons of this subject by preference in the middle of a half-day, avoiding fringe periods.

(D) Respect double periods

Warning: Use with care

This option is only effective when used sparingly and thoughtfully since it imposes considerable restrictions on the optimisation function, especially with regard to subjects with many double periods. Activate this function only when a previous optimisation run was unable to achieve the desired outcome and you have already increased the relevant weighting parameter (' Avoid errors with double periods ') to '5'.

•Please note that the correct treatment of double periods requires an appropriate input under option 'Double periods min.-max'.

•The use of the code (D) excludes the use of the codes (2) and (C)

(E) Double periods are allowed to span *-breaks

Breaks marked with an asterisk (*) must not be bridged by double periods and will therefore affect the distribution of double periods. If this restriction is not desired for a particular subject, simply uncheck this option.

(P) No break supervision before/after

This code is only relevant in combination with the module Break supervision .

Some subjects like PE require some preparation and follow-up. This code ensures that a teacher teaching this subject is not assigned a break supervision before or after the lesson.

(S) Office hour

This code is only relevant in combination with WebUntis.
