You will learn to

Tell which evaluation items still carry evidence, and rebuild a set once it has been used for fixing.

Why this matters

A held-out set is spent the first time someone reads its failures and edits the system.

Three things to remember

  • An item used to fix the system stops being evidence about it.
  • Record what each item has been used for, and when.
  • Refill the held-out set before the next round; do not reuse it.

Task

Fifty held-out questions; the twelve failures were read and used to change the instructions.

Try the judgement yourself

Both answers respond to the task above. One of them does the job better. Which, and why?

Make something yourself

Take any check you repeat — a mock test, a monthly report review. Write which items you have already used to fix things, and how you would collect a clean set.

A useful starting pointFour parts: the set, the items already used, why they are spent, and the refill plan.
