Introduction
The test papers will be marked by external markers. The markers will follow the mark
scheme in this booklet, which is provided here to inform teachers.
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:
■ the teaching points from the key stage 3 programme of study
■ the marks available for each part of the question
■ the total marks available for the question
■ the answer or expected answers, indicated by an asterisk
■ additional guidance to assist markers in making professional judgements.
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 2 question 11 and from
tier 5–7 paper 2 question 4, illustrates this.
Where more than one answer is acceptable, this is indicated in the mark scheme by
‘any one from’. Each possible correct answer is marked with an asterisk. In some
cases, alternative answers are indicated by ‘or’.

In the following example from part a of tier 3–6 paper 2 question 3, an answer giving
‘crushed into powder’ and ‘smoother and broken into pieces’ will be awarded two
marks. However, an answer which gives ‘smooth like a pebble’ will be given only one
mark, as ‘smooth’ and ‘like a pebble’ are equivalent answers.
In the following example, from part a of tier 5–7 paper 2 question 11, the statement in
bold type in the Additional guidance column is given in order to indicate the general
requirement of the question.
In the Accept column there may be:
■ examples of answers which are acceptable, although they do not correspond exactly
to the expected answers
■ 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:
■ answers which are not acceptable
■ a reminder, in questions involving calculations, that consequential marking may
be used
■ instructions on action in the event of consequential marking (see page 5)
■ guidance to markers where pupils have not followed the instructions in
the question.

accept ‘smoking 5cigarettes a day is lessharmful than smoking 20’
accept statements suchas ‘20 cigarettes a day isworse when you are45–64 than under 45’accept the converse
one conclusion should relate to the number
of cigarettes and the other to the effect of age
statements that do not make a generalisation,such as ‘nearly 1% of men aged 55–64 whosmoke 20 cigarettes a day will die of heartdisease’ are insufficient

Marking
The number of marks available for each part of a question, and the maximum number
of marks for the question as a whole, are shown on the question paper. Every part of
a question which has been attempted by a pupil will be marked and the mark for each
part recorded in the mark box alongside that part. Half marks will not be given in any
question.
The total number of marks awarded for all the parts of questions on a double page
will be written in the box at the bottom of the right-hand page. In some instances, this
will be the sum of marks awarded for two questions. The total number of marks
obtained on the paper will be recorded on the front of the test paper.
The total number of marks available is 180 in tier 3–6 and 150 in tier 5–7.
Using professional judgement in marking
The instructions given in the mark scheme will enable the markers to decide whether
pupils have correctly answered a particular question. However, there will be instances
where an answer given by a pupil does not correspond to any of the possible responses
shown in the mark scheme. In such cases, markers will apply their professional
judgement to decide if credit should be given. They will consider whether the response:
■ is equivalent to those listed
■ conveys the ideas underlying the question as outlined in the statement in bold typein the mark scheme, if one is given.
If any doubt persists, markers will consult their supervisors for guidance.
Marking misspellings of words
If a pupil misspells a word, markers will apply the following procedures:
■ if it is clear that the pupil has made a simple error, eg ‘tow’ for ‘two’ or ‘Son’ for
‘Sun’, then the incorrect spelling will be accepted and the mark awarded
■ if a pupil misspells a word copied from the text of the question or from a selection
given, and the new word does not have any inappropriate meaning, the incorrect
spelling will be accepted and the mark awarded
■ if specific scientific vocabulary is required in the answer, a misspelling must, in
order to be creditworthy, be a phonetic equivalent of the required word, with the
major syllables of the correct word represented in the answer.

Marking lists of alternative answers
In some instances, pupils give more than one answer to a single question. If any of the
answers given is incorrect, the mark will not be awarded, irrespective of the order in
which the answers are given. In some cases, a correct answer is given alongside other
answers which, while correct, would be insufficient for the mark. In these cases, the
mark will be given for the correct answer.
Marking questions containing calculations
Some questions require pupils to perform calculations. Where two marks are available,
they are advised to show their working. Pupils who do not show their working but
give the correct answer will be awarded full marks.
The result of one calculation may be required in order to carry out further
calculations. In such instances:
■ the term ‘consequential marking’ appears in the Additional guidance
■ a pupil’s result for the first calculation is treated as the starting point for the second
■ the pupil is awarded full credit for the second calculation if it is carried out
correctly, even if the result of the first calculation was wrong.
Marking answers given in the wrong place
In some cases, pupils may write correct answers in the wrong part of the question.
Markers will use professional judgement to decide whether a pupil has correctly
understood the question and simply written the answer in the wrong place. Similarly,
if pupils identify an answer by a cross or other indication when a tick is required,
they will be given credit for their responses.
Awarding levels
Level threshold tables, which show the mark ranges for the award of different levels,
will be available on the NAA website www.naa.org.uk/tests from 23 June 2008.
The 2008 key stage 3 science tests and mark schemes were developed by
the National Foundation for Educational Research (NFER) on behalf of QCA.
