, General Marking Guidance
All candidates must receive the same treatment. Examiners must markthe 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 totheir
perception of where the grade boundaries may lie.
There is no ceiling on achievement. All marks on the mark scheme shouldbe
used appropriately.
All the marks on the mark scheme are designed to be awarded. Examinersshould
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 belimited.
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 itwith an
alternative response
