, General Marking Guidance
• All candidates must receive the same treatment.
Examiners must mark the first candidate in exactly
the same way as they mark the last.
• Mark schemes should be applied positively.
Candidates must be rewarded for what they have
shown they can do rather than penalised for
omissions.
• Examiners should mark according to the mark
scheme not according to their perception of
where the grade boundaries may lie.
• There is no ceiling on achievement. All marks on the mark
scheme should be used appropriately.
• 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 may be limited.
• When examiners are in doubt regarding the application of the
mark scheme to a candidate’s response, the team
leader must be consulted.
• Crossed out work should be marked UNLESS the candidate has
replaced it with an alternative response.
