General Marking Guidance
l
22 ce
20 dex
• All candidates must receive the same treatment. Examiners must mark the first
E
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 have been developed so that the rubrics of each mark scheme reflects the characteristics of the
22 ce
skills within the AO being targeted and the requirements of the command word. So for example the command
20 dex
word ‘Explain’ requires an identification of a point and then reasoning/justification of the point.
E
Explain questions can be asked across all AOs. The distinction comes whether the identification is via a judgment
made to reach a conclusion, or, making a point through application of knowledge to reason/justify the point made
through application of understanding. It is the combination and linkage of the marking points that is needed to
gain full marks.
When marking questions with a ‘describe’ or ‘explain’ command word, the detailed marking guidance below should
be consulted to ensure consistency of marking.
Assessment Command Word
Objective
Strand Element Describe Explain
AO1* An answer that combines the An explanation that links identification of a point
marking points to provide a logical with reasoning/justification(s) as required
description
AO2 An answer that combines the An explanation that links identification of a point
marking points to provide a logical (by applying knowledge) with
description, showing application of reasoning/justification (application of
knowledge and understanding understanding)
AO3 1a and An answer that combines points of
1b interpretation/evaluation to provide
a logical description
AO3 2a and An explanation that combines identification via a
2b judgment to reach a conclusion via
justification/reasoning
AO3 3a An answer that combines the
marking points to provide a logical
description of the
plan/method/experiment
AO3 3b An explanation that combines identifying an
improvement of the experimental procedure with
a linked justification/reasoning
*there will be situations where an AO1 question will include elements of recall of knowledge directly from the
specification (up to a maximum of 15%). These will be identified by an asterisk in the mark scheme.
