    Assessment Criteria

    Key criteria assessors look for in your portfolio

    • Award credit for correctly selecting and wearing appropriate personal protective equipment (safety boots, hi-vis, gloves) throughout the task.
    • Check that the candidate accurately sets out the wall using dimensions from a plan, with corner profiles or gauging rods if provided.
    • Assess for consistent mortar bed and perpend joints (typically 10mm) and a fair face unless otherwise specified.
    • Confirm that the wall is plumb, level, and in face plane at regular intervals during construction.
    • Evidence of correct mixing ratios (e.g., 1:5 cement to sand) and appropriate mortar consistency.
    • Ensure that tools (trowel, spirit level, line and pins) are used correctly and maintained in clean condition.
    • Verify that the candidate clears loose mortar debris, washes tools, and stacks unused bricks/blocks neatly.
    • Assess awareness of COSHH when handling cement and the use of barrier creams or gloves to prevent skin contact.
    • Award credit for demonstrating accurate measurement and setting out, with lines and levels checked.
    • Credit for consistent mortar mix that is neither too dry nor too wet, used efficiently.
    • Observe correct bricklaying sequence, including corner leads and bond pattern.

    Assessment Guidance

    Guidance for achieving higher grades

    • 💡Always refer to the specification or work instructions before starting; check the required bond pattern and joint finish.
    • 💡Take time to set up a reliable string line between corner profiles—correct setup prevents costly rework.
    • 💡Use a gauging rod or measuring rule to mark course heights on a corner pole; this ensures uniform bed joints and reduces cutting.
    • 💡Work methodically, building the corners or leads first, then running the line between them, laying to the line without disturbing it.
    • 💡Carry out regular self-checks with a level and tape measure, and photograph key stages as evidence for your portfolio.
    • 💡Manage your time to include a thorough clean-up; assessors will observe how you leave the work area and store materials.
    • 💡Always read the full task brief and specifications before starting; plan your work sequence to maximize efficiency and quality.
    • 💡Demonstrate a systematic approach: measure twice, cut once; check levels frequently during construction.
    • 💡Use the correct bonding pattern as specified, maintaining half-bond unless instructed otherwise for straight walls.
    • 💡Show awareness of sustainability by minimizing mortar waste and recycling where possible, and by cleaning bricks for reuse.
    • 💡During practical assessments, verbalize your safety checks when observed to demonstrate understanding even if not explicitly asked.
    • 💡In practical assessments, narrate your process to the assessor—explain why you are checking for level, plumb, and range alignment at each stage.
    • 💡Allocate time for final cleanup and tool maintenance; unstowed tools or scattered debris can result in lost marks under 'tidy up work area' criteria.
    • 💡Before starting, double-check material quantities and condition—using chipped bricks or the wrong mortar mix can undermine the entire task.
    • 💡When answering questions about health and safety, always refer to specific legislation (e.g., Health and Safety at Work Act 1974) and explain how it applies to a given scenario. This shows depth of understanding.
    • 💡For practical assessments, focus on accuracy over speed. Examiners look for correct measurements, proper tool use, and adherence to safety protocols. Rushing often leads to mistakes that cost marks.
    • 💡In written exams, use technical terminology correctly (e.g., 'cavity wall' instead of 'double wall'). This demonstrates your knowledge of industry language and can earn you higher marks.

    Common Mistakes

    Common errors to avoid in your coursework

    • Failing to check level and plumb frequently, resulting in a wall that leans or bows.
    • Using a mortar mix that is too wet or dry, leading to weak bonding, slump, staining, or difficulty in tooling.
    • Not setting out with a gauge rod, causing uneven course heights and exceeding the tolerance for brickwork.
    • Neglecting to dampen high-absorption bricks or blocks before use in dry conditions, weakening mortar adhesion.
    • Leaving mortar droppings on the face of the wall or allowing them to harden, damaging the final appearance.
    • Inadequate cleaning of the spirit level after use, causing inaccuracies due to hardened mortar on the surface.
    • Forgetting to dampen bricks/blocks before laying, causing poor adhesion and weak joints.
    • Inconsistent mortar mix ratios leading to weak or excessively stiff mortar.
    • Failure to check for level and plumb regularly, resulting in leaning or uneven walls.
    • Neglecting to protect and clean finished brickwork from mortar stains.
    • Inadequate site tidy-up, leaving tools dirty or misplaced, and waste not disposed properly.
    • Neglecting to dampen bricks before laying in hot conditions, causing rapid moisture loss from mortar and weak bonding.
    • Relying solely on visual judgement rather than using a spirit level after every course, leading to cumulative out-of-plumb errors.
    • Forgetting to overlap vertical joints in blockwork properly, which reduces structural strength and may be rejected during inspection.
    • Applying mortar that is too wet, causing slumping and uneven settlement; or too dry, leading to poor adhesion and cracking.
    • Failing to protect work from rain or frost, which can ruin uncured mortar and necessitate rebuilding.
    • Misconception: 'Health and safety is just common sense, so I don't need to study it.' Correction: Health and safety regulations are legal requirements that must be followed precisely. Many accidents occur because workers rely on 'common sense' rather than formal procedures like method statements and COSHH assessments.
    • Misconception: 'All bricks are the same, so I can use any type for any job.' Correction: Bricks vary in strength, water absorption, and thermal properties. Using the wrong brick can lead to structural failure or damp issues. Always check the specification for the intended use.
    • Misconception: 'Once I've learned a skill, I don't need to practice it.' Correction: Construction skills require regular practice to maintain accuracy and speed. Even experienced tradespeople continue to refine techniques like bricklaying or sawing to ensure quality.
