IntroductionThe Pearson Edexcel Level 1/Level 2 GCSE (9-1) in Combined Science is designed for usein schools and colleges. It is part of a suite of GCSE qualifications offered by Pearson.These sample assessment materials have been developed to support thisqualification and will be used as the benchmark to develop the assessment studentswill take.Pearson Edexcel Level 1/Level 2 GCSE (9-1) in Combined ScienceSample Assessment Materials – Issue 2 – October Pearson Education Limited 20171

General marking guidance All candidates must receive the same treatment. Examiners must mark the lastcandidate in exactly the same way as they mark the first. Mark schemes should be applied positively. Candidates must be rewarded for whatthey have shown they can do rather than be penalised for omissions. Examiners should mark according to the mark scheme – not according to theirperception of where the grade boundaries may lie. All the marks on the mark scheme are designed to be awarded. Examiners shouldalways award full marks if deserved, i.e. if the answer matches the mark scheme.Examiners should also be prepared to award zero marks if the candidate’s responseis not worthy of credit according to the mark scheme. Where some judgement is required, mark schemes will provide the principles bywhich marks will be awarded and exemplification/indicative content will not beexhaustive. When examiners are in doubt regarding the application of the mark scheme to acandidate’s response, a senior examiner must be consulted before a mark is given. Crossed-out work should be marked unless the candidate has replaced it with analternative response.Subject specific marking guidanceSymbols, terms used in the mark scheme Round brackets ( ): words inside round brackets are to aid understanding of themarking point but are not required to award the point Curly brackets { }: indicate the beginning and end of a list of alternatives (separatedby obliques) where necessary to avoid confusion Oblique /: words or phrases separated by an oblique are alternatives to each otherand either answer should receive full credit. ecf: indicates error carried forward which means that a wrong answer given in anearly part of a question is used correctly to a later part of a question.You will not see ‘owtte’ (or words to that effect). Alternative correct wording shouldbe credited in every answer unless the ms has specified specific.The Additional Guidance column is used for extra guidance to clarify any points inthe mark scheme. It may be used to indicate: what will not be accepted for that marking point in which case the phrase ‘do notaccept’ will be alongside the relevant marking point it might have examples of possible acceptable answers which will be adjacent to thatmarking pointPearson Edexcel Level 1/Level 2 GCSE (9-1) in Combined ScienceSample Assessment Materials – Issue 2 – October Pearson Education Limited 20173
Specific Marking Guidance for Levels Based Mark SchemesStep 1 – Finding the right levelThe first stage is to decide which level the answer should be placed in. Examinersshould first make a holistic judgement on which level most closely matches thestudent response and place it within that level. Students will be placed in the levelthat best describes their answer.Answers can display characteristics from more than one level, and where thishappens examiners must use their professional judgement to decide which level ismost appropriate using a ‘best-fit’ approach. For example if a student’s workmainly evidences the skills of level 2 but has some level 3 skills present theresponse would be placed in level 2 but the mark awarded would be towards thetop of level 2, reflecting the evidence given from level 3.Step 2 – Determining the markAfter a level has been decided on, the next stage is to decide on the mark withinthe level. The instructions below tell you how to reward responses within a level.Examiners should be prepared to use the full range of marks available in a leveland not restrict marks to the middle.Examiners should start at the middle of the level (or the upper middle mark if thereis an even number of marks) and then move the mark up or down to find the bestmark.To do this, you should take into account how far the answer meets therequirements of the level:4 If it meets the requirements fully, you should be prepared to award full marks withinthe level. The top mark in the level is used for answers that are as good as canrealistically be expected within that level. If it only barely meets the requirements of the level, examiners should considerawarding marks at the bottom of the level. The bottom mark in the level is used foranswers that are the weakest that can be expected within that level. The middle marks of the level are used for answers that have a reasonable match tothe descriptor. This might represent a balance between some characteristics of thelevel that are fully met and others that are only barely met.Pearson Edexcel Level 1/Level 2 GCSE (9-1) in Combined ScienceSample Assessment Materials – Issue 2 – October Pearson Education Limited 2017
