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.
