How the invigilation roster works

Each block explains one part of how this works and how to read the result.

Inputs
Provide comma-separated teachers, rooms, and exam slots (e.g. “10 Sep Morning”). Every room is staffed for every slot.
Teachers are assigned in rotating order so duty counts stay as even as possible.
Source
Equal-load round-robin assignment. Institutions may apply seniority or subject constraints — adjust the teacher list order to bias early slots.

Frequently asked questions

Can two teachers share a large hall?

List the room twice (e.g. Hall A-1, Hall A-2) or run a second pass for co-invigilators.

How is fairness measured?

The API returns duty counts per teacher. With T teachers and N room-slots, counts differ by at most 1.

Can I exclude a teacher from a slot?

Remove them from the list for a partial roster, or edit the printed chart manually after generation.

Does this cover flying squads?

No — it assigns room invigilators only. Add flying-squad staff as a separate roster.
