The client asks what the training achieved
The programme ended, renewal is due, and the client wants a report. What you have is a grade sheet: "Mohammed, 78%". That tells an HR manager nothing about what Mohammed can now do.
Every item is linked to the skill it measures, so each trainee gets a mastery report by skill rather than by score, and the client gets a view of which skills the team mastered and which need another session — which is, incidentally, a sales opportunity.
