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.
• Types of mark
o M marks: method marks
o A marks: accuracy marks
o B marks: unconditional accuracy marks (independent of
M marks)
• Abbreviations
o cao – correct answer only
o ft – follow through
o isw – ignore subsequent working
o SC - special case
o oe – or equivalent (and appropriate)
o dep – dependent
o indep – independent
