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 36 and 57The 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 answers expected, 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 36 paper 2 question 15 and from

tier 57 paper 2 question 7, illustrates this.

Where more than one answer is acceptable, this is indicated in the mark scheme byany 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 partb of tier 36 paper 1 question 3, an answer giving

water and minerals will be awarded two marks. However, an answer which gives

minerals and nutrients will be given only one mark, as both points are correct

answers for the same mark.

In the following example, from part d iii of tier 57 paper 1 question 13, the

statement inbold type in the Additional guidance column is given in order to indicate

the general requirement of that part 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 below)

guidance to markers where pupils have not followed the instructions on the question.

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 36 and 150 in tier 57.

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 inbold type

in the mark scheme, if one is given.

If any doubt persists, markers will consult with 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 creditworthy misspelling

must 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 pupils 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.

In a planning question, if no answer is given in the expected place but the correct

answer is given in the drafting box, the mark(s) will be given.

Awarding levels

The sum of the marks gained on both papers determines the level awarded. A copy of

the level threshold tables which show the mark ranges for the award of different levels

will be sent to each school by QCA on 30 June 2006.

Schools will be notified of pupils results by means of a marksheet, which will be

returned to schools by the External Marking Agency with the pupils marked scripts.

The marksheet will include pupils scores on the test papers and the levels awarded.

The 2006 key stage 3 science tests and mark schemes were developed by the Oxford,

Cambridge and RSA Examinations (OCR) and the Centre for Research into Primary

Science and Technology (CRIPSAT) on behalf of QCA.
