Marking the science tests
The Standards and Testing Agency (STA) is responsible for the development and delivery ofstatutory tests and assessments in 2012. The STA is an executive agency of the Departmentfor Education (DfE).
This booklet contains the mark schemes for tests A and B. The test papers will be marked byexternal markers employed by the external marking agency under contract to STA. Themarkers will follow the mark schemes in this booklet, which is supplied to teachers forinformation.
General guidance
The structure of the mark schemes
The marking information for each question is set out in the form of tables.
The ‘Question’ column on the left-hand side of each table provides a quick reference to thequestion number, question part and the area of the programme of study assessed.
The ‘Mark’ column gives the number of marks available for each question part.
The ‘Requirements’ column may include three types of information:■ a general statement describing what is required for the award of marks■ examples of specific creditworthy responses demonstrating correct science■ examples of creditworthy responses that are beyond the Key Stage 2 programme of study.
The ‘Allowable answers’ column gives examples of allowable creditworthy responses,showing correct science which may not be as clearly expressed.
The ‘Additional guidance’ column may include different types of information:■ specific responses which are not creditworthy either because information from the
question has been rephrased, or because incorrect scientific knowledge is implied■ answers which are insufficient in themselves to gain credit, but are not incorrect
science, and would therefore not lose credit if combined with a correct response.
Applying the mark schemes
The mark schemes give scientifically correct answers to each question as well as providingguidance on, and examples of, other answers which are allowable. In cases of alternativewording, or where an answer is drawn rather than written, external markers will exercisetheir professional judgement.

The pupil gives two or moreresponses to a particularquestion part.
The pupil has not used ticksto indicate the correctresponse in a multiple-choice question.
The pupil ticks more thanthe required number ofboxes.
The pupil misspells a word.
a) If a pupil qualifies a scientifically correct answer with a scientifically incorrectstatement, no mark will be awarded for that question part.
b) If a pupil qualifies a scientifically correct answer with an incorrect statementwhich is not relevant to the context of the question, the latter response isregarded as ‘neutral’ and the mark will be awarded.
Any unambiguous positive indication of the correct answer will be accepted. Tickstake precedence over any other form of response. Therefore, when ticks and any other sort of response are given together, the boxes with ticks will beassumed to be the pupil’s response. If the correct boxes are left blank, no markswill be awarded.
One mark will be deducted for each incorrect answer.Negative marks will not be awarded.
a) 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.
b) If a pupil misspells a word copied from the text of the question or from aselection given, and the new word does not have any inappropriate meaning,the incorrect spelling will be accepted and the mark awarded.
c) If specific scientific vocabulary is required in the answer, a creditworthymisspelling must be a phonetic equivalent of the required word, with the major syllables of the correct word represented in the answer.
What if...? Marking procedure
Recording marks awarded
The number of available marks is recorded in the margin of the test booklet,alongside each question part, and also in the second column of the mark scheme.Depending on the type of response made to each part of each question by thepupil, the marker will award one of the following:
2 or 1, as appropriate, for a creditworthy response0 for an incorrect response– if no response is made.
The marking is conducted online by external markers using scanned images ofthe pupils’ work. Each paper has 40 marks available.
To ensure consistency of marking, the most frequent queries are listed below,along with the action the marker will take.
