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.
