General marking guidance
• All candidates must receive the same treatment. Examiners must mark
the last candidate in exactly the same way as they mark the first.
• Mark schemes should be applied positively. Candidates must be
rewarded for what they have shown they can do rather than be
penalised for omissions.
• Examiners should mark according to the mark scheme – not according to
their perception of where the grade boundaries may lie.
• All the marks on the mark scheme are designed to be awarded.
Examiners should always award full marks if deserved, i.e. if the answer
matches the mark scheme. Examiners should also be prepared to award
zero marks if the candidate’s response is not worthy of credit according
to the mark scheme.
• Where some judgement is required, mark schemes will provide the
principles by which marks will be awarded and exemplification/indicative
content will not be exhaustive.
• When examiners are in doubt regarding the application of the mark
scheme to a candidate’s response, a senior examiner must be
consulted before a mark is given.
• Crossed-out work should be marked unless the candidate has replaced it
with an alternative response.
