Subject Specific Marking Instructions INTRODUCTION Your first task as an Examiner is to become thoroughly familiar with the material on which the examination depend• the specification, especially the assessment objectives • the question paper and its rubrics • the mark scheme. You should ensure that you have copies of these materials. You should ensure also that you are familiar with the administrative procedures related to the marking process. ThInstructions for Examiners. If you are examining for the first time, please read carefully Appendix 5 IntroductioExaminers. Please ask for help or guidance whenever you need it. Your first point of contact is your Team Leader. USING THE MARK SCHEME Please study this Mark Scheme carefully. The Mark Scheme is an integral part of the process that begins with thewith the awarding of grades. Question papers and Mark Schemes are developed in association with each other soachievement can be addressed from the very start. This Mark Scheme is a working document; it is not exhaustive; it does not provide ‘correct’ answers. The Mark Scabout how the question will work out, and it is subject to revision after we have looked at a wide range of scripts. The Examiners’ Standardisation Meeting will ensure that the Mark Scheme covers the range of candidates’ respoExaminers understand and apply the Mark Scheme in the same way. The Mark Scheme will be discussed and amprocedures will be confirmed. Co-ordination scripts will be issued at the meeting to exemplify aspects of candidateordination scripts then become part of this Mark Scheme. Before the Standardisation Meeting, you should read and mark in pencil a number of scripts, in order to gain an imachievement that may be expected. In your marking, you will encounter valid responses which are not covered by the Mark Scheme: these responsesanswers which fall outside the ‘target range’ of Bands for the paper which you are marking. Please mark these anPlease read carefully all the scripts in your allocation and make every effort to look positively for achievement throprepared to use the full range of marks. H046/01 Mark Scheme LEVELS OF RESPONSE QUESTIONS: The indicative content indicates the expected parameters for candidates’ answers, but be prepared to recognise athey show relevance. Using ‘best-fit’, decide first which set of BAND DESCRIPTORS best describes the overall quality of the answer. Oconcentrating on features of the answer which make it stronger or weaker following the guidelines for refinement. • Highest mark: If clear evidence of all the qualities in the band descriptors is shown, the HIGHEST Mark s• Lowest mark: If the answer shows the candidate to be borderline (i.e. they have achieved all the qualitiesevidence of meeting the criteria of the band in question) the LOWEST mark should be awarded. • Middle mark: This mark should be used for candidates who are secure in the band. They are not ‘borderlithe qualities in the band descriptors. Be prepared to use the full range of marks. Do not reserve (e.g.) high Band 3 marks ‘in case’ something turns up answer gives clear evidence of the qualities described in the band descriptors, reward appropriately. H046/01 Mark Scheme AO1 AO2 High (thorough) Precision in the use of question terminology. Knowledge shown is consistent and welldeveloped. Clear appreciation of the question from a range of different perspectives making extensive use of acquired knowledge and understanding. Knowledge and understanding shown is consistently applied to context enabling a logical and sustained argument to develop. Examples used enhance rather than detract from response. cdMiddle (reasonable) Awareness of the meaning of the terms in the question. Knowledge is sound and effectively demonstrated. Demands of question understood although at times opportunities to make use of acquired knowledge and understanding not always taken. Knowledge and understanding applied to context. Whilst clear evidence that an argument builds and develops through response there are times when opportunities are missed to use an example or relate an aspect of knowledge or understanding to the context provided. TcstoLow (basic) Confusion and inability to deconstruct terminology as used in the question. Knowledge partial and superficial. Focus on question narrow and often onedimensional. Inability to apply knowledge and understanding in any sustained way to context resulting in tenuous and unsupported statements being made. Examples if used are for the most part irrelevant and unsubstantiated
