Moderation
Internal moderation
When several teachers in a Centre are involved in internal assessment, arrangements must be made within
the Centre for all candidates to be assessed to the same standard. It is essential that the marks for each skill
assigned within different teaching groups (or classes) are moderated internally for the whole Centre entry.
The Centre assessments will then be moderated externally by Cambridge.
External moderation
External moderation of internal assessment is carried out by Cambridge. Centres must submit candidates’
internally assessed marks to Cambridge. The deadlines and methods for submitting internally assessed
marks are in the Cambridge Administrative Guide available on our website.
Once it has received the marks, Cambridge will draw up a list of sample candidates whose work will be
moderated (a further sample may also be requested), and will ask the Centre to send immediately every
piece of work that has contributed towards these candidates’ final marks. Individual Candidate Record
Cards and Coursework Assessment Summary Forms must also be sent with the coursework. All remaining
coursework and records should be kept by the Centre until results are published.
Ideally, Centres should use loose-leaf A4 file paper for practical written work, as this is cheaper to send by
post. Original work is preferred for moderation, but authenticated photocopies can be sent if absolutely
necessary.
Pieces of work for each skill should not be stapled together. Each piece of work should be clearly and
securely labelled with:
• the skill being assessed
• the Centre number
• the candidate’s name and number
• the title of the experiment
• a copy of the mark scheme used
• the mark awarded.
