,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
C
the answer matches the mark scheme. Examiners should also be
prepared to award zero marks if the candidate’s response is
LE
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.
ST
When examiners are in doubt regarding the application of the
mark scheme to a candidate’s response, the team leader must
be consulted.
BE
Crossed out work should be marked UNLESS the candidate has
replaced it with an alternative response.
, 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.
C
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
LE
together in a meaningless manner. Answers must be in the correct context.
Quality of Written Communication
ST
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
BE
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.
