, 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.
Mark schemes will indicate within the table where, and which strands of QWC, are
being assessed. The strands are as follows:
i) ensure that text is legible and that spelling, punctuation and grammar are accurate so
that meaning is clear
ii) select and use a form and style of writing appropriate to purpose and to complex
subject matter
iii) organise information clearly and coherently, using specialist vocabulary when appropriate
