,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
, Using the Mark Scheme
Examiners should look for qualities to reward rather than faults to penalise. This does NOT mean giving credit for
incorrect or inadequate answers, but it does mean allowing candidates to be rewarded for answers showing correct
application of principles and knowledge. Examiners should therefore read carefully and consider every response: even if
it is not what is expected it may be worthy of credit.
The mark scheme gives examiners:
an idea of the types of response expected
how individual marks are to be awarded
the total mark for each question
examples of responses that should NOT receive credit.
/ means that the responses are alternatives and either answer should receive full credit.
( ) means that a phrase/word is not essential for the award of the mark, but helps the examiner to get the sense of the
expected answer.
Phrases/words in bold indicate that the meaning of the phrase or the actual word is essential to the answer.
ecf/TE/cq (error carried forward) means that a wrong answer given in an earlier part of a question is used correctly in
answer to a later part of the same question.
Candidates must make their meaning clear to the examiner to gain the mark. Make sure that the answer makes sense.
Do not give credit for correct words/phrases which are put together in a meaningless manner. Answers must be in the
correct context.
Quality of Written Communication
Questions which involve the writing of continuous prose will expect candidates to:
write legibly, with accurate use of spelling, grammar and punctuation in order to make the meaning clear
select and use a form and style of writing appropriate to purpose and to complex subject matter
organise information clearly and coherently, using specialist vocabulary when appropriate.
Full marks will be awarded if the candidate has demonstrated the above abilities.
Questions where QWC is likely to be particularly important are indicated (QWC) in the mark scheme, but this does not
preclude others.
