Markers should: • Familiarise themselves with the question and answer before evaluating the responses of candidates. • Always interpret the responses of the candidates within the context of the question. • Consider any relevant and acceptable answer during pre-marking but should strictly adhere to the answers after finalisation of the marking guideline. • There are TWO approaches to answering questions; these are (1) to describe and (2) to explain. 1. If a candidate is required to explain e.g., a process in 4 steps, only the first 4 responses should be considered. 2. However, if for example candidate is required to explain or describe a process, we need to consider that that candidates may write a long description, not necessarily well organised. In this case, the marker needs to evaluate the complete statement to judge if the candidate explained the required outcome satisfactorily and allocate marks on merit. • Mark what the candidate wrote and do not interpret or predict responses. • Indicate the tick or cross right at the position where the mark needs to be awarded or where the candidate made the error. • Accept the letter corresponding with the correct answer as well as the answer written in full in multiple-choice questions or similar questions. • Accept incorrect spelling in answers unless the spelling changes the meaning of the answer. • If a learner writes two or more answers separated by a slash (/) mark only the first response, unless the additional answer/s are different names for the same item e.g., Yale lock/Night latch. In this case, the answer for the response should be awarded and the slash (/) should NOT be considered as an additional answer. 2. For calculations: • A mark is only awarded if the correct unit is written next to the answer. If the question states that the answer must be in a specific unit, a mark will ONLY be awarded if the answer has the correct unit as indicated in the question. • Marks will only be allocated for the correct values if the candidates add instead of multiply. NO marks will be awarded for the calculations and the answer. • Where an incorrect answer is correctly carried over, the marker must recalculate the values, using the incorrect answer from the first calculation. If correctly used, the candidate should receive the full marks for subsequent calculations. • Alternative methods of calculations must be considered, provided that the correct answer is obtained. • For the calculation of quantities marks will be awarded for the correct use of the dimension paper.

When marking drawings: • The member for which the mark should be awarded should be drawn correctly in the correct position to receive a mark. • A member incorrectly drawn but wrongfully repeated in another position will be awarded the mark for the repeated incorrect member provided that the marking guideline provide for TWO or more marks for that member (positive marking). • Marks can only be awarded for a label if the label is correctly indicating the correct member. Do not consider labels for members of which the labels were provided on the answer sheet. • Scale drawings should always be marked using an appropriate mask. • If the incorrect/wrong drawing was drawn, the candidate can be awarded for only what was provided for on the marking guideline. • If a line diagram or an orthographic view instead of a pictorial drawing (isometric/oblique/perspective) is drawn, the first assessment criteria for each member will be marked wrong, but marks will be awarded for the subsequent members if TWO or more marks are awarded for the same member. • If candidates draw/give more information than what is required, mark strictly according to the assessment criteria. 4. Incorrect numbering of questions: • If a candidate numbered an incorrectly, but the answer is in the correct position according to the sequence of the questions in the question paper, circle then the incorrect numbering and mark the response. • If questions were answered randomly not following the same sequence as in the question paper and the learner numbered incorrectly, the response should NOT be marked. 5. Duplication of responses and questions answered in the correct place: • If a question is answered twice, mark the first response. • If a question should be answered on an answer sheet and the candidate answered it on both the answer sheet and in the answer book, mark the response on the answer sheet and cancel the response in the answer book. • If the question was answered in the answer book instead of on the answer sheet, mark the response in the answer book according to the assessment criteria on the marking guideline.
