Introduction
This booklet includes the mark scheme for paper 1 and paper 2 in both tiers.
The structure of the mark scheme for tiers 3–6 and 5–7
The mark scheme for each question shows:
I
the teaching points from the key stage 3 programme of study
I
the marks available for each part of the question
I
the total marks available for the question
I
the answer or expected answers indicated by an asterisk
I
additional guidance to assist markers in making professional judgements.
In the Accept column there may be:
I
examples of answers which are acceptable, although they do not correspond exactly to the expected answers
I
some examples of higher-level answers, which could be given by higher-attaining pupils answering questions on the lower levels in the tier.
In the Additional Guidance column there may be:
I
examples of answers which are insufficient or not acceptable
I
information on the general requirement of the question
I
a reminder, in questions involving calculations, that consequential marking may be used
I
instructions on action in the event of consequential marking (see p5)
I
guidance to markers where pupils have not followed the instructions in the question.
When a question appears in an identical form in both tiers, the answers to the question are given only once in the mark scheme. For clarity, both question numbers are given. The following example, from tier 3–6 paper 1 question 16 and from tier 5–7 paper 1 question 8, illustrates this.
