  • Enter the unavailability of the courses

Courses inherit the unavailability and wishes of their resources: teacher(s), class(es), room(s), and equipment.  You can add unavailability and wishes specific to courses. This allows you, for example, to assign specific time slots to courses in certain subjects for certain classes.

1. Distinguish between unavailability, optional unavailability, and wishes

Unavailability (red)

Unavailability (red) should be reserved for essential cases, when the course is not supposed to be held during a time slot. During automatic placement, EDT does not place any courses in its unavailable time slots. 

For example, if 9th-grade math classes are never held in the afternoon, you mark all afternoons as unavailable.


Optional unavailability (orange)

Optional unavailability slots (orange) are used to indicate the time slots during which it would be preferable for a course to be held. During automatic placement, optional unavailability is treated by EDT as unavailability until you decide to ignore it in order to resolve course in failure. 

For example, if it is truly preferable that math courses not be scheduled in the afternoons, you can set optional unavailability for all afternoons.

 

Note
When you decide to ignore optional unavailability to resolve courses in failure, these are the optional unavailability for all courses, which are temporarily ignored. Therefore, do not enter mandatory requirements as optional unavailability.

Wishes (green)

The wishes (green) allow the specify the time slots during which it would be preferable for a course to be held. During automatic placement, EDT tries to take these into account, but they are by no means guaranteed, unlike unavailability or time constraints.

For example, if it's better (though not important) for math classes to be held in the morning, you should list that wish every morning.

2. Enter a course's unavailability or wish

  1. Go to the display Timetable > Staff > Unavailability, wishes and constraints and select the course.
  2. On the right-hand panel, above the time grid, make sure the correct paintbrush (red, orange, or green) is selected.
  3. If unavailability has already been entered for the resources for the course, they appear on the schedule with a gray hatched pattern.
  4. Click and drag the paintbrush over the time grid to paint the time slots affected by unavailability or a wish.

3. Delete an unavailability or a wish for a course

To delete an unavailability or a wish, select the paintbrush of the same color and click and drag over the painted area.



4. Enter an unavailability or a wish for a multi-selection of courses

If several courses have the same unavailability, you can enter them in a single operation. To do this, select all the concerned courses, then click and drag the red paintbrush on the grid.
For example, you want all 9th-grade math courses to never be held in the morning.



Advice
There are several ways to quickly select all courses in a subject for a specific level. You can use the shortcut Ctrl + E (Extract > Specify an extraction) from the list of courses or extract courses from the list of subjects (or classes) using the shortcut Ctrl + U (Extract > Extract the courses of the selection) then sort the list by class (or subject).
