,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 thanpenalised for omissions.
Examiners should mark according to the mark scheme not according to
their perception of where the grade boundariesmay 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 mustbe consulted.
Crossed out work should be marked UNLESS the candidate has replaced it
with an alternative response.
