A diagnostic at the start of a programme places people on a level. It is short on purpose. Its job is to stop a capable committee member sitting through foundation material, and to stop an operations colleague being asked for an advanced practicum they have not been prepared for. The diagnostic is not a ranking of staff.
Module checks ask for application. Recognising a definition is a weak signal that someone will notice a missing constraint in a live paper. We would rather see a marked-up page than a perfect score on terminology. Where a multiple-choice item appears, it is a filter, not the result the organisation is invited to file.
The programme ends with a practicum: a longer case, incomplete on purpose, with a requirement to write the decision path. Participants may use their notes. They may not use an outside adviser. The artefact is a short memorandum, not a slide deck.
A failed practicum can be retaken once after a documented review of the first attempt. A second failure is recorded as incomplete. We do not raise a score after a conversation off the record. If the organisation wants coaching rather than assessment, that is a different engagement and is labelled as such.
