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. • If a candidate is required to explain e.g., a process in 4 steps, only the first 4 responses should be considered. • If, however a candidate is required to e.g., explain or describe how to transfer heights from one point to another using a transparent pipe level we need to consider that candidates may write a long description not necessarily well organised as an intellectual response may do. 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. The marker should apply his/her professional judgement with these types of questions. • Mark what the candidate wrote and do not award marks for answers that the marker thinks the candidate meant with what was written. • 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. • Accept incorrect spelling in one-word answers unless the spelling changes the meaning of the answer. 2. For calculations: • A mark is only awarded if the correct unit is written next to the answer. • If TWO marks are awarded ONE mark is awarded for the answer and ONE mark for the correct unit. • Where the candidate made a principle error e.g. added instead of multiplying, no marks will be awarded for the steps. If the answer is correct according to what the candidate did, the mark for the answer can be awarded for the application of skills. • Where an incorrect answer could be carried over to the next step, the first answer will be deemed incorrect. However, should the incorrect answer be carried over correctly, the marker has to recalculate the values, using the incorrect answer from the first calculation. If correctly used, the candidate should receive the full marks for subsequent calculations. • Markers should consider when and where a candidate has rounded off in a calculation, as well as the subsequent effect it has on the final answer obtained. The calculation should therefore be awarded marks on merit. • Alternative methods of calculations must be considered, provided that the correct answer is obtained.

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. • Scale drawings should always be marked using an appropriate mask. When a candidate drew the wrong drawing e.g.: • A horizontal section instead of a vertical section, no marks will be allocated to the drawing as the candidate did not respond to the expected outcome. • An orthographic view instead of sectional view, no marks will be allocated to the drawing as the candidate did not respond to the expected outcome. • An orthographic view instead of an isometric view, no marks will be allocated to the drawing as the candidate did not respond to the expected outcome. • If the incorrect drawing was drawn, the candidate can be awarded for only what was asked but mark/s for the correctness of the drawing will not be awarded e.g., if a King Post roof truss was asked in the question, and candidate drew SA-Howe Truss.
