, 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.
