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 penalized 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.
