Enter constraints on a lesson-by-lesson basis
-
Lesson-specific constraints allow for a more precise reflection of certain pedagogical and equipment-related constraints than subject-specific constraints. These constraints can be lifted when resolving failures.
- Go to the display Timetable > Lesson > Lesson to lesson constraints.
- From the list, select the lessons you want to link, then click on Add a constraint.
- In the pop-up window, select the type of constraint to apply:
- Enforce the placement of selected lessons the same two-week period/half-day/full day/custom number of half-days
For example, to group laboratory classes into a half-day to make it easier to prepare the lab rooms, or to group certain lessons on the same day so that students at the same level can progress at the same pace through the lesson program of the week. - Prohibit the placement of selected lessons the same two-week period/half-day/full day/custom number of half-days
For example, to prevent students from having the same teacher twice in the same afternoon, even if he/she is teaching them different subjects. - Set the order of the selected classes in the week
For example, to enforce that, for a particular subject, the 1h30 lessons are held before the 1h lessons during the week. - Prohibit selected lessons from being scheduled back-to-back
Make sure the selected lessons follow one another
For example, when two teachers want to work on a joint project. This approach is an alternative to designing a complex lesson.
- Enforce the placement of selected lessons the same two-week period/half-day/full day/custom number of half-days
- In the pop-up window, you can optionally enter a designation for this constraint.
The box Optional constraint is ticked by default: if the constraint is optional, it will be taken into account during automatic placement but can be lifted when resolving failures (tick Search options > Ignore the optional lesson-to-lesson constraints - if the constraint must be strictly adhered to, un-tick this box. - Click on Create: the constraints and associated lessons appear in the list.
Note
If you created a constraint of the type Define the order of selected lessons within the week you can modify the order of the lessons using the button
