Reconciling School and External Results When a Student's Profile Is Inconsistent
A student's school-assessed work averages 78% across translation, commentary and set-text analysis, with commentary the weakest strand at 68%. In the external examination the same student scores 84% overall, with the set-text section at 88% and the unseen translation at 80%. The school's moderation sample flags the student because the school-assessed commentary marks sit well below the external set-text marks. The teacher must decide whether the school marks are too harsh, too generous, or simply measuring something the external paper does not.
1. Diagnose the most likely explanation for the gap and say what evidence would confirm or refute it.

The most likely explanation is that the two assessments sample different skills. The school commentary task requires sustained written argument about stylistic choices over 150-200 words, marked against band descriptors for coverage and evidence. The external set-text section rewards identification and analysis under time pressure with shorter responses. A student can be strong at the latter and weaker at sustained argument, which fits the profile: commentary 68%, set-text 88%.
An alternative explanation is marker severity in the commentary strand. To distinguish, look for:
- Within-strand consistency: do other students show the same commentary-versus-set-text gap, or is this student an outlier? A cohort-wide gap suggests severity; a single outlier suggests a skill profile.
- Task alignment: does the school commentary task's descriptor match the external analysis criteria, or does it demand more (e.g. two devices plus evaluation)? If it demands more, lower marks are expected.
- Blind re-marking: an independent mark of a sample of commentary scripts would settle severity directly.
The gap alone is not evidence of error. Moderation flags inconsistency; it does not diagnose its cause.
2. The teacher proposes to raise the commentary marks so the school average better predicts the external result. Evaluate this proposal.

The proposal inverts the purpose of moderation. Moderation checks whether school judgements are consistent with the standards; it does not adjust school marks to fit a later external outcome. Three problems:
- Circularity: the external result is being used as the criterion for the school mark, but the external paper tests a partly different construct. Matching the numbers would conceal the real difference rather than resolve it.
- Effect on other students: raising this student's commentary marks raises the strand mean and shifts every other student's relative position without any change in their work.
- Loss of information: the commentary marks currently tell the school something useful, namely that sustained stylistic argument is a weakness. Erasing that signal removes the basis for teaching.
The defensible action is to verify the commentary marking against the descriptors using an independent sample, adjust only if severity is demonstrated, and in either case use the finding to target the commentary skill. If the descriptors are shown to be harsher than the external criteria, revise the task for the following year, not the marks already awarded.
