1 Marking the mathematics tests As in 2006, external markers, employed by the external marking agencies under  contract to QCA, will mark the test papers. The markers will follow the mark schemes  in this booklet, which is supplied to teachers for information. This booklet contains the mark schemes for the levels 3–5 tests A, B and mental  mathematics. Level threshold tables will be available on the NAA website  (www.naa.org.uk/tests) on 25 June 2007. General guidance The structure of the mark schemes The marking information for each question is set out in the form of tables, which start  on page 6 of this booklet. The ‘question’ column on the left-hand side of each table  provides a quick reference to the question number and the question part. The ‘mark’  column indicates the total number of marks available for each question part. On some  occasions the symbol  U1  may be shown in the mark column. The ‘U’ indicates that  there is a Using and applying mathematics element in the question. The number, 1, shows the number of marks attributed to using and applying mathematics in this  question. The ‘requirement’ column may include two types of information:   a statement of the requirements for the award of each mark, with an indication of       whether credit can be given for correct working   examples of some different types of correct response. The ‘additional guidance’ column indicates alternative acceptable responses, and  provides details of specifi c types of response which are unacceptable. Other guidance,  such as the range of acceptable answers, is provided as necessary. Additionally, for the mental mathematics test, general guidance on marking is given on  page 16, together with a ‘quick reference’ mark scheme.  Applying the mark schemes In order to ensure consistency of marking, the most frequent procedural queries are  listed on pages 2 and 3 with the action the marker will take. This is followed by further  guidance on pages 4 and 5 relating to the marking of questions that involve money,  time and other measures. Unless otherwise specifi ed in the mark scheme, markers will  apply the following guidelines in all cases. 275357_KS2_Maths_MS.indd Sec1:1275357_KS2_Maths_MS.indd Sec1:1 22/1/07 8:47:50 pm22/1/07 8:47:50 pm

2 What if ... Marking procedure The pupil’s response is numerically or algebraically  equivalent to the answer in  the mark scheme.Markers will award the mark unless the mark scheme states otherwise. The pupil’s response does  not match closely any of the  examples given.Markers will use their judgement in deciding whether the response corresponds with  the statement of the requirements given in the ‘requirement’ column. Reference will  also be made to the additional guidance and, if there is still uncertainty, markers will  contact the supervising marker. The pupil has responded  in a non-standard way.Calculations, formulae and written responses do not have to be set out in any  particular format. Pupils may provide evidence in any form as long as its meaning  can be understood. Diagrams, symbols or words are acceptable for explanations or  for indicating a response. Any correct method of setting out working, however  idiosyncratic, will be accepted. There appears to be a  misreading affecting  the working.This is when the pupil misreads the information given in the question and uses  different information without altering the original intention or diffi culty level of the  question. For each misread that occurs, one mark only will be deducted.  In one-mark questions – 0 marks are awarded. In two-mark questions that have a method mark – 1 mark will be awarded if the  correct method is correctly implemented with the misread number. No answer is given in  the expected place, but  the correct answer is  given elsewhere.Where a pupil has shown understanding of the question, the mark(s) will be given.  In particular, where a word or number response is expected, a pupil may meet the  requirement by annotating a graph or labelling a diagram elsewhere in the question. The response in the answer  box is wrong, but the  correct answer is shown  in the working.Where appropriate, detailed guidance will be given in the mark scheme, which markers  will follow. If no guidance is given, markers  will examine each case to decide whether:   the incorrect answer is due to a      transcription error   the pupil has continued to give redundant     extra working which does not contradict     work already done   the pupil has continued to give redundant     extra working which does contradict work    already done.If so, the mark will be awarded. If so, the mark will be awarded. If so, the mark will not be awarded. 275357_KS2_Maths_MS.indd Sec2:2275357_KS2_Maths_MS.indd Sec2:2 22/1/07 8:47:51 pm22/1/07 8:47:51 pm

3 What if ... Marking procedure The pupil’s answer is  correct but the wrong  working is shown.A correct response will always be marked as correct. The correct response has  been crossed out and  not replaced.Any legible crossed-out work that has not been replaced will be marked  according to the mark scheme. If the work is replaced, then crossed-out work  will not be considered. More than one answer  is given.If all answers are correct (or a range of answers is given, all of which are  correct), the mark will be awarded unless prohibited by the mark scheme.  If both correct and incorrect responses are given, no mark will be awarded. The answer is correct  but, in a later part of the  question, the pupil has  contradicted this response.A mark given for one part will not be disallowed for working or answers given  in a different part, unless the mark scheme specifi cally states otherwise. The pupil has drawn lines  which do not meet at the  correct point.Markers will interpret the phrase ‘slight inaccuracies in drawing’ to mean  ‘within or on a circle of radius 2mm with centre at the correct point’. within the circle acceptedon the circle acceptedoutside the circle not accepted Recording marks awarded on the test paper All questions, even those not attempted by the pupil, will be marked with a ‘1’ or ‘0’  entered in each marking space. A two-mark question which is correct will have ‘1’ entered in both marking spaces. A two-mark question which is incorrect, but which has suffi cient evidence of working  or method as required by the mark scheme, will have ‘1’ entered in the fi rst marking  space and ‘0’ in the second. Otherwise ‘0’ will be entered in both marking spaces. For the written tests, the total number of marks gained on each double page will be  written in the space at the bottom of the right-hand page. For all of the tests, the total  number of marks gained on each paper will be recorded on the front of the test paper,  and on the mark sheet. Test A carries a total of 40 marks. Test B also carries a total of 40 marks. The mental  mathematics test carries a total of 20 marks. The 2007 key stage 2 mathematics tests and mark schemes were developed by the  Test Development Team at Edexcel on behalf of QCA. 275357_KS2_Maths_MS.indd Sec2:3275357_KS2_Maths_MS.indd Sec2:3 22/1/07 8:47:51 pm22/1/07 8:47:51 pm

16 Mark scheme for the mental mathematics test Applying the mark scheme Please note that pupils will not be penalised if they record any information given in  the question or show their working. Markers will ignore any annotation, even if in the  answer space, and mark only the answer. Markers will accept an unambiguous answer  written in the stimulus box, or elsewhere on the page. Full mark scheme information is given on page 18. In addition, a ‘quick reference’  mark scheme is provided on page 17. This is presented in a similar format to the pupil’s  answer sheet. General guidance The general guidance for marking the written tests also applies to marking the mental  mathematics test. In addition, the following principles apply. 1.  Unless stated otherwise in the mark scheme, accept answers written in words, or    a combination of words and fi gures. 2.  Where units are specifi ed, they are given on the answer sheet. Pupils are not       penalised for writing in the units again. 3.  Where answers are required to be ringed, do not accept if more than one answer is       ringed, unless it is clear which is the pupil’s intended answer. Accept also any other       way of indicating the correct answer, eg underlining. 275357_KS2_Maths_MS.indd 016275357_KS2_Maths_MS.indd 016 22/1/07 8:47:57 pm22/1/07 8:47:57 pm
