,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:
3
, SECTION A: Clinical Psychology
Question Answer Mark
Number
1(a) AO1 (1 mark) (1)
One mark for a definition of reliability in relation to
classification systems.
For example:
A classification system for mental health is
reliable if there is consistent diagnosis of mental
health between clinicians (1).
Look for other reasonable marking points.
Question Answer Mark
Number
1(b) AO1 (2 marks), AO3 (2 marks) (4)
One mark for identification of each reason (AO1).
One mark for justification of each reason (AO3).
For example:
Different classification systems such as DSM and
ICD may diagnose different mental health for a
person presenting with the same symptoms so
they may lack concurrent validity (1), as shown
by Cooper et al. (1972) where the same patient
was diagnosed with schizophrenia twice in New
York two times more than in London (1).
Classification systems cannot always accurately
predict how effective treatments will be for a
given disorder, so they may lack predictive
validity (1) as shown by Kuyken et al. (2008)
who found that 75% of his participants stopped
taking anti-depressants and more relapsed
compared to MCBT, so classification systems
cannot predict who anti-depressants will work
for (1).
Look for other reasonable marking points.
