Assessment Criteria
Key criteria assessors look for in your portfolio
- Award credit for demonstrating accurate transfer of setting out details onto timber components using recognised marking tools (e.g., dividers, trammels, try squares) without dimensional errors exceeding specified tolerances.
- Look for evidence that the candidate has interpreted the contract specification and drawings to select the correct timber species, moisture content, and grain orientation, clearly marking for any defects or knots to be avoided.
- Expect the candidate to apply safe work practices throughout, including the use of appropriate PPE (e.g., safety boots, eye protection) and ensuring the work area is free from slip, trip, and manual handling hazards.
- Assess the candidate's ability to identify and select the correct quality and quantity of materials (e.g., seasoned ash, elm) and tools (e.g., mortise gauge, bevel) needed for the marking out process, minimising waste.
- Confirm that the candidate has checked and maintained tools for accuracy (e.g., squares for squareness, tapes for stretch) before use, recording any checks as per company procedures.
- Award credit for the candidate's careful handling of materials to avoid damage such as bruising or splitting during marking out, and for protecting surrounding surfaces and completed work from accidental marking.
- Verify that the marking out is completed within the allocated timeframe without compromising accuracy, and that the candidate proactively manages their time by prioritising tasks and seeking clarification when needed.
- Check that all marking out complies fully with the given contract information, including dimensions, profiles, and any specific joint details (e.g., mortise and tenon locations) for wheelwrighting products, and that the candidate has recorded any deviations or issues.
Assessment Guidance
Guidance for achieving higher grades
- 💡Always start by thoroughly reviewing the contract drawings, specifications, and any setting out information before picking up a marking tool; time spent planning is never wasted.
- 💡Use the ‘measure twice, cut once’ philosophy—visually re-check all dimensions and markings against the original information and, where possible, ask a colleague to verify critical measurements.
- 💡Maintain a clean, organised bench and frequently clear away shavings or dust that could obscure your marks or cause slips; a tidy workspace is a safe and accurate one.
- 💡For curved work like wheel felloes, use full-size rods or templates where provided, and transfer marks using stable reference lines; prick punches can help preserve centre points during handling.
- 💡If you encounter any ambiguity in the setting out details, raise a Request for Information (RFI) immediately rather than making assumptions that could lead to non-conformance.
- 💡Keep your marking tools in good condition: regularly check squares, gauges, and trammels for accuracy, and store them to prevent damage. A blunt knife or scriber will produce wide, imprecise lines.
- 💡Manage your time by breaking down the marking out into logical steps, and avoid interruptions; if using a radial arm or jig, ensure it is correctly set up before marking multiple pieces.
- 💡When marking out mortise and tenon joints on curved stock, ensure you reference from the same face and edge consistently, and clearly mark which side is the shoulder to prevent assembly errors.
- 💡Tip 1: When compiling your portfolio, include clear photographs with annotations showing the sequence of work, tools used, and how you checked accuracy. This provides strong evidence of competence.
- 💡Tip 2: During professional discussions, use technical terminology correctly (e.g., 'plumb', 'level', 'square', 'reveal') and explain why you chose specific methods or materials. This demonstrates depth of understanding.
- 💡Tip 3: For the 'erecting structural timber' unit, practice setting out and fixing roof trusses or floor cassettes. Show that you can interpret loading diagrams and ensure temporary stability during construction.
Common Mistakes
Common errors to avoid in your coursework
- Misinterpreting scale or dimensions on setting out drawings, leading to components being marked too large or too small; often caused by not checking the drawing scale or misreading measurements.
- Failing to account for timber movement or moisture content when marking out, resulting in joints that become loose or tight after seasoning, especially in wheelwrighting where precise fit is critical.
- Using marking tools that are not calibrated or are worn (e.g., a try square that is out of true), which compounds errors across multiple marks and leads to the entire assembly being out of square.
- Marking in the wrong order, such as marking tenon shoulders before referencing a face side and face edge, causing misalignment when assembling wheel components.
- Neglecting to clearly mark reference points and centre lines on curved components like wheel rims, making it difficult to achieve symmetrical shaping later.
- Overlooking the need to minimise waste by not nesting components efficiently on stock, which is a common oversight when planning the marking out of multiple identical pieces.
- Ignoring safety protocols such as securing workpieces properly before marking, leading to slips that can cause inaccurate marks or personal injury.
- Rushing through double-checks against the specification to meet time constraints, resulting in costly rework or material wastage due to uncaught errors.
- Misconception: 'The NVQ is just about practical skills, so theory doesn't matter.' Correction: You must also demonstrate knowledge of building regulations, material properties, and safe working practices through written evidence and professional discussions.
- Misconception: 'You can use any type of timber for any job.' Correction: Different timbers have different strengths, moisture content, and durability. For example, softwood is common for structural framing, while hardwood is used for high-wear joinery like stair treads.
- Misconception: 'Once you've fixed something, it's fine to move on without checking.' Correction: Continuous quality checks during installation are vital. A misaligned door frame, for instance, can cause issues with hinges and locks later.
