,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.
