,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.
