,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.
