Mark Scheme
Sample paper
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.

SAMPLE PAPER
DESIGN AND TECHNOLGY: FOOD TECHNOLOGY
MARK SCHEME
This mark scheme is intended as a guide to the type of answer expected but is
not intended to be exhaustive or prescriptive. If candidates offer other answers
which are equally valid they must be given full credit.
Responses are to be assessed according to the quality of the work rather than the
number of points included. The following level descriptors are intended to be a guide when
assessing the quality of a candidate’s response.
Low
The candidate has a basic but possibly confused grasp of the issues.
Few correct examples are given to illustrate points made. This candidate does
not have a clear idea of what s/he is writing about
Intermediate The candidate has some knowledge but there will be less clarity of
understanding. Some correct examples given to illustrate points made. This
candidate knows what s/he is writing about but is confused in part.
High The candidate has a thorough understanding of the issues and has provided
relevant examples to support the knowledge shown. This candidate knows what
s/he is writing about and provides clear evidence of understanding.

(a)
Candidates should respond by producing 2 annotated sketches.
For each sketch:

Design ideas should be for a savoury hand held pastry, which
includes a savoury filling, appeals to consumers from different
cultures and offers sensory appeal.
 Ideas should be communicated through sketches, including 2D,
3D or cross section.
Annotation should show:
 Suitability for a hand held, pastry product e.g. Non crumbly,
/greasy, small size, not too hot to touch.
 Should include a savoury filling e.g. meat, poultry, egg,
cheese, fish, and vegetable based ingredients.
 Suitability for providing sensory appeal e.g. aroma, colour,
texture, shape, variety of flavours, finishing techniques….
 Appeal to consumers from different cultures e.g. may refer to
use of spices, multicultural ingredients e.g. curry, sweet and
sour flavours, range of vegetables used, sweet potatoes, halal
meats...
 Credit may also be given for extra design information e.g.
 Finishing techniques, cooking / preparation methods, portion
control.
Marks awarded as follows:
For each sketch:
