, MARK SCHEME – GCSE COMBINED SCIENCE: TRILOGY – 8464/C/1H –
JUNE 2020
Mark schemes are prepared by the Lead Assessment Writer and considered,
together with the relevant questions, by a panel of subject teachers. This mark
scheme includes any amendments made at the standardisation events which all
associates participate in and is the scheme which was used by them in this
examination. The standardisation process ensures that the mark scheme covers
the students’ responses to questions and that every associate understands and
applies it in the same correct way.
As preparation for standardisation each associate analyses a number of students’
scripts. Alternative answers not already covered by the mark scheme are
discussed and legislated for. If, after the standardisation process, associates
encounter unusual answers which have not been raised they are required to refer
these to the Lead Examiner.
It must be stressed that a mark scheme is a working document, in many cases
further developed and expanded on the basis of students’ 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.
