How does Marking work?

Every mark, on the line, explained. A paper, its memo and a batch of scanned scripts go in; every script comes back with the memo's ticks on the line of working that earned them, each with a one-line reason, the totals added by arithmetic — with a mark sheet, an item analysis for the next lesson and a note for the parent.

  1. Paper, memo and scripts go in

    A paper, its memo as a PDF and the scanned scripts in a batch.

  2. Leo marks against the memo

    Every tick on the line of working that earned it, with a one-line reason.

  3. Clara checks every mark

    A second program on another model; it speaks only when a check fails.

  4. The trial run and its gate

    A handful marked your way first; at the gate you press Mark the rest.

  5. The teacher decides and signs

    Accept, override with a reason or flag; you approve and sign the batch.

  6. A script is a reference, never a name

    Identifier stickers or a covered name; the platform holds no learner name.

Leo and Clara are computer programs, not people. Marked by Leo (AI), moderated by Clara (AI), signed by your teacher.

The six steps in full

  1. Paper, memo and scripts go in. You open a paper (its title, subject, grade and total marks), upload the memo as a PDF, and upload the scanned scripts in a batch. Leo reads the memo and the validation report shows every sub-question found, the marks at the mark points and whether the totals add up; you correct anything it questions and approve the memo.
  2. Leo marks against the memo. Every tick lands on the line of working that earned it, with a one-line reason in the memo's own words; the totals are added by arithmetic, never guessed.
  3. Clara checks every mark against a checklist — a second program on another model — and speaks only when a check fails: a tick with no line of working, a total that does not add up, a mark the memo does not allow. Agreement is silent.
  4. The Trial run and its gate. Nothing is marked in bulk before you have seen Leo mark a few scripts your way: the trial marks a handful, you see the marks side by side with your own, and at the gate you press Mark the rest or adjust a decision on the memo and run the trial again.
  5. The teacher decides and signs. Accept a tick, override it with a reason, or raise a flag; a decision on what the memo meant re-marks the batch; you approve the scripts and sign the batch. Only then do marked scripts leave the workspace.
  6. A script is known by a reference, never a name. The workspace prints identifier stickers, or you cover the learner's name before scanning; the platform holds no learner name, and the register of identifiers stays with the school.

The three styles

The same marks, rendered three ways: the AI style with the memo reason beside each tick and the totals typed; the human style with red-pen ticks and crosses and subtotals in the margin; and My hand, learned from a teacher's own marked scripts. You choose per paper; the reasons stay in the record whichever style you print.

The same mark in three stylesThree panels show the same two lines of working. In the first, a small tick with the memo reason beside it. In the second, a large red-pen tick and a subtotal in the margin. In the third, a tick in a teacher's own hand.

Leo: A computer program, not a person. Named for Leonhard Euler. Clara is a computer program too, not a person.

Leo marks and Clara checks; neither signs. Nothing a learner writes trains any model. Leo is named for Leonhard Euler; Clara is the second program's name — both are computer programs, not people, and the page says so wherever they appear.
