, 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.
