A release is an event, not a switch. The PDFs that went out are fixed copies of the grades as they stood, so correcting a score in the class record does not change a card anybody already holds. Putting it right takes a new release.
The order to do it in
- On Release, press Take back the release.
- Write the reason. It is for you — it shows on the revisions list, not on any card.
- Take it back. Every emailed link stops working immediately.
- Correct the score in the class record, and let the grade recompute.
- Come back to Release, clear the pre-flight panel, and release again. The summary now reads "Revision 2, replacing the release you took back."
The new cards carry that revision number and new reference codes, and the earlier revisions are listed on the Release page with the date and your reason.
What a release closes and what it does not
While a period is released, its teacher's comments and its observed values are closed — "the report cards for Term 1 are already released, so their comments are closed." Take the release back to change either. Scores are not locked, so a subject teacher can still correct one; that is exactly why the card in a parent's hand and the gradebook can disagree until you release again.
What if
- Only one grade is wrong, in one subject. There is no per-learner release. Take the whole period back and release it again; every card is rebuilt from the same grades, so nothing else moves.
- A parent scans the old card's QR. It reports that the release was taken back and should not be relied on. That is the point of the code: an out-of-date card says so.
- You took it back by mistake. Release the period again straight away. The cards are identical apart from the revision number and new references.
- The learner already opened the old card. They keep the file. Send the new one and say which revision it is — the number is printed on the card.
