INSTRUCTIONS FOR MARKERS

1.    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 describe and explain type of
          questions.
             1. If a candidate is required to explain e.g., a process in a prescribed
                 number of steps (e.g. 3 steps), only the first required number of
                 responses should be considered.
             2. However, if for example candidate is required to explain or describe a
                 process, we need to consider 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.
       • Answering short questions.
              1. Bullet Form Answers: When a candidate provides their answers in
                  bulleted points, each bullet should be treated as a single answer.
                  Award 1 mark for each complete bulleted response.
              2. Paragraph Form Answers: When a candidate provides answers in
                  paragraph form, the response should be evaluated based on the
                  accuracy and completeness of each fact presented. Award marks for
                  each distinct fact or point made, ensuring that each fact is correctly
                  articulated.
      • 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 be
          awarded if the answer is indicated without the unit.
      • 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.

                                    NSC – Marking guidelines

      •    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.
3.    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 provides 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. However, if the additional information
          alters or contradicts the correct response, the answer should be marked
          incorrect.
4.    Incorrect numbering of questions:
      • If a candidate numbered incorrectly, but the answer is in the correct position
          according to the sequence of the questions in the question paper, circle 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.
