Mark Scheme
2010 examination - January series
, PMT
Mark schemes are prepared by the Principal Examiner and considered, together with the
relevant questions, by a panel of subject teachers. This mark scheme includes any
amendments made at the standardisation meeting attended by all examiners and is the scheme
which was used by them in this examination. The standardisation meeting ensures that the
mark scheme covers the candidates’ responses to questions and that every examiner
understands and applies it in the same correct way. As preparation for the standardisation
meeting each examiner analyses a number of candidates’ scripts: alternative answers not
already covered by the mark scheme are discussed at the meeting and legislated for. If, after
this meeting, examiners encounter unusual answers which have not been discussed at the
meeting they are required to refer these to the Principal Examiner.
It must be stressed that a mark scheme is a working document, in many cases further
developed and expanded on the basis of candidates’ reactions to a particular paper.
Assumptions about future mark schemes on the basis of one year’s document should be
avoided; whilst the guiding principles of assessment remain constant, details will change,
depending on the content of a particular examination paper.
