0445_s26_ms_322026 May-June Design and Technology 0445 Mark Scheme 3 Variant 2

This is the official Cambridge mark scheme for Design and Technology (0445) Mark Scheme 3 (Variant 2) from the 2026 May-June session. Mark schemes show exactly how each mark is awarded, including acceptable alternative answers, required key terms, and common errors that lose marks. Cambridge mark schemes use notation like "allow," "accept," and "do not credit" to define the boundary between full marks and zero.

Paper 3: Resistant Materials This is Paper 3: Resistant Materials, worth 50 marks with a duration of 1h 15m. Section A: short, sometimes one-word, knowledge questions on tools, processes and materials (wood, metal, plastic). Section B: longer questions with large mark allocations requiring clear sketches with detailed written notes. Candidates must match tools and equipment to specific purposes — generic names ('saw', 'sandpaper') are not credited.

This mark scheme corresponds to 0445_s26_qp_32. For maximum revision benefit, attempt the question paper under strict exam conditions first, then use this mark scheme to self-assess. Pay attention to the marking notation: "allow" means an alternative is accepted, "do not credit" means a specific phrasing is rejected even if technically correct, and "ORA" (or reverse argument) means the mark can also be earned with the opposite reasoning.

Cambridge mark schemes reward precise language. For Design and Technology (0445), look for keywords the examiner requires — definitions must include specific terms (e.g., "per unit mass," "resultant"), and calculations must show working even if the final answer is correct. Understanding mark scheme conventions helps you write answers that hit every marking point, not just the general idea.

Generic material names and generic reasons not credited (Paper 1 + Paper 3)

Candidates should be advised against giving generic names of materials such as wood, or generic reasons, such as easy to work with, as these are not awarded marks0445 Paper 1, May/June 2025

How to fix: Name a specific material (oak, beech, acrylic, MDF, Corriflute, mild steel, aluminium, HDPE) AND give a property-linked reason (resistance to corrosion, strength-to-weight ratio, ability to fold flat, available in a range of colours). Never write 'wood', 'plastic', 'metal' or 'easy to work with' — those are zero-mark phrases. Match the material to what your design actually needs to do.

2

Sketches without notes (or notes without sketches) on (b) joining/method questions — capped at 1 mark per method

To score maximum marks, candidates must use both sketches and notes to show each method. A small number of candidates produced only sketches and were awarded a maximum of one mark for each method0445 Paper 1, May/June 2025

How to fix: Every (b) joining/method question requires BOTH a labelled sketch AND written notes. A sketch alone caps you at 1 mark per method. Train yourself to add at least two annotation lines to every sketch — name the parts, name the action ('compresses to grip', 'rotates around pin'), and name the tool used.

5

Tools named generically ('saw', 'cutter', 'sandpaper') instead of specific tools — Paper 3

Many candidates named abrasives such as 'sandpaper', (glasspaper), which was inappropriate as it is an abrasive that is used on wood, not metal. There were a few correct answers stating 'emery cloth' and 'wet and dry' paper0445 Paper 3, May/June 2025

How to fix: Memorise specific tool names by material: hole saw / Forstner bit (Ø80 holes in wood), scriber (marking metal), centre punch (indenting metal before drilling), odd-leg calipers (parallel lines on metal), hand/flat/half-round file (smoothing metal/acrylic edges), emery cloth or wet-and-dry (silicon carbide) paper for metal/acrylic, glasspaper for wood only. Generic names earn zero.
