Technology 2 Hlayiso/Mock 2026 Senior Phase – Marking Guidelines GENERAL MARKING GUIDELINES 1. One tick (✓) = one mark. 2. Accept answers that are worded differently but are technologically correct. Accept spelling that is clearly understandable. 3. Where a question asks for a number of answers (e.g. TWO), mark only the first answers given, in the order given. 4. Calculations: award marks for the formula/substitution and for the correct answer with the correct unit as shown. Apply consistent accuracy (CA): if an incorrect answer from an earlier part is used correctly later, award the later marks. 5. Drawings: use the rubrics given. Drawings done freehand on the annexures (without a ruler) lose the neatness/line-quality mark only. 6. Answers that appear in brackets ( ) are alternatives or extra information and are not required for the mark. COGNITIVE LEVELS (approximate): Knowledge/recall 30 marks (30%), comprehension and application 50 marks (50%), analysis, evaluation and design/drawing (higher order) 20 marks (20%).
