Teachers' availability (wishes)

A teacher's availability tells the software which time slots are impossible (black, hard constraints), undesirable (red, soft constraints) or preferred (green). In secondary education the term wishes is also used — it is the same concept, when the teacher enters their theoretical weekly availability and the school uses it for timetable generation (possibly after adjusting or weighting it).

The solver strictly respects the impossible slots and does its best to respect the undesirable / preferred ones depending on the other constraints.

Two modes depending on the timetable type

• Weekly timetable — availability entered on the typical week, validated by the administration before generation. A later change is flagged but does not interfere.
• Calendar timetable (on Premium accounts) — availability entered date by date, consolidated in real time. Conflicts are detected as they arise.

Entry by teachers themselves

Teachers can enter their own availability from their account (teacher portal) — a major time saver for the administration. They can also receive a direct share link to the availability screen (without having to sign in), generated from Download with an expiry date.
