    Assessment Criteria

    Key criteria assessors look for in your portfolio

    • Award credit for demonstrating the ability to interpret and follow the given information, including drawings, specifications, and schedules, to determine the correct installation sequence and material requirements.
    • Look for evidence that the learner checks materials for defects, handles them safely, and positions underlay with correct overlaps, tension, and temporary fixings.
    • Assess that battens are accurately spaced, aligned, and fixed to the rafters using appropriate fasteners, ensuring compatibility with the roofing tile/slate gauge and wind uplift calculations.

    Assessment Guidance

    Guidance for achieving higher grades

    • 💡For the NVQ portfolio, provide photographic evidence with clear annotations showing underlay laps, batten gauge, and fixings, referencing the manufacturer’s data and British Standards.
    • 💡Ensure you record and explain any deviations from the specification and the reasoning, as this demonstrates competence in problem-solving and compliance with contract information.
    • 💡Model safe working, including use of roof ladders, edge protection, and manual handling, and capture these in your witness testimonies.
    • 💡**Build a Robust Portfolio:** Your portfolio is your primary evidence. Ensure it's meticulously organised, clearly annotated, and directly links each piece of evidence (photos, videos, witness testimonies, job sheets, risk assessments) to specific performance criteria and knowledge requirements. Quality, relevance, and quantity of evidence are key.
    • 💡**Master the 'Why' as well as the 'How':** During professional discussions and observations, assessors will probe your understanding. Be prepared to articulate the reasons behind your material choices, installation methods, and safety procedures. Explain *how* you comply with Building Regulations and British Standards, demonstrating a comprehensive grasp of your trade.
    • 💡**Prioritise Health & Safety in Practice:** Consistently demonstrate exemplary health and safety practices. This includes proactive risk assessment, appropriate use of PPE, safe working at height, and proper handling of materials and equipment. Your commitment to safety will be assessed throughout your practical observations and portfolio evidence.

    Common Mistakes

    Common errors to avoid in your coursework

    • Neglecting to check that the roof structure is dry, clean, and conforms to tolerances before starting underlay installation, leading to out-of-square or uneven substrate.
    • Using incorrect nail types or insufficient penetration into rafter depth, causing batten detachment under load.
    • Applying underlay with insufficient laps or inadequate drape, risking water ingress and condensation issues.
    • "The Level 3 NVQ is just about showing you can do the job." Correction: While practical competence is paramount, the Level 3 NVQ requires you to demonstrate a deep understanding of *why* certain methods are used, *how* to plan complex tasks, and *how* to apply relevant regulations and standards, often through professional discussions and detailed portfolio evidence.
    • "Any roofing work I do will count towards my NVQ." Correction: Evidence must specifically demonstrate competence against the detailed *National Occupational Standards* (NOS) for each unit. This means your work needs to be varied enough to cover all criteria, and you'll need to provide specific documentation, observations, and explanations tailored to those standards.
    • "Flat roofing is simpler than pitched roofing, so it's an easier NVQ." Correction: Flat roofing systems (e.g., single-ply, built-up felt, liquid applied) involve highly specific installation techniques, critical detailing for falls and drainage, and complex considerations for thermal bridging and vapour control. Achieving competence in flat roofing at Level 3 requires an equivalent level of skill, precision, and technical knowledge as advanced pitched roofing.
