2 This mark scheme has been written by the Assessment Writer and refined, alongside the relevant questions, by a panel of subject experts through the external assessment writing process and at standardisation meetings. The purpose of this mark scheme is to give you: examples and criteria of the types of response expected from a learner information on how individual marks are to be awarded the allocated assessment objective(s) and total mark for each question. Marking guidelines General guidelines You must apply the following marking guidelines to all marking undertaken throughout the marking period. This is to ensure fairness to all learners, who must receive the same treatment. You must mark the first learner in exactly the same way as you mark the last. The mark scheme must be referred to throughout the marking period and applied consistently. Do not change your approach to marking once you have been standardised. Reward learners positively, giving credit for what they have shown, rather than what they might have omitted. Utilise the whole mark range and always award full marks when the response merits them. Be prepared to award zero marks if the learner s response has no relevant material. Do not credit irrelevant material that does not answer the question, no matter how impressive the response might be. The marks awarded for each response should be clearly and legibly recorded in the grid on the front of the question paper. If you are in any doubt about the application of the mark scheme, you must consult with your Team Leader or the Chief Examiner. Guidelines for using extended response marking grids Extended response marking grids have been designed to award a learner s response holistically and should follow a best-fit approach. The grids are broken down into levels, with each level having an associated descriptor indicating the performance at that level. You should determine the level before determining the mark. When determining a level, you should use a bottom up approach. If the response meets all the descriptors in the lowest level, you should move to the next one, and so on, until the response matches the level descriptor. Remember to look at the overall quality of the response and reward learners positively, rather than focussing on small omissions. If the response covers aspects at different levels, you should use a best-fit approach at this stage, and use the available marks within the level to credit the response appropriately. When determining a mark, your decision should be based on the quality of the response in relation to the descriptors. Standardisation materials, marked by the Chief Examiner, will help you with determining a mark. You will be able to use exemplar learner responses to compare against live responses, to decide if they are the same, better or worse. You are reminded that the indicative content provided under the marking grid is there as a guide, and therefore you must credit any other suitable responses a learner may produce. It is not a requirement either that learners must cover all of the indicative content to be awarded full marks. 2
