    Assessment Criteria

    Key criteria assessors look for in your portfolio

    • Award credit for demonstrating correct foundation preparation: trench dug to firm subsoil, min. depth 150mm, width approx. 600mm wider than wall base, and base levelled with a spirit level.
    • Assess use of appropriate foundation stones: large, flat stones placed with best face down, ensuring stability and no rocking; smaller stones used for packing but not for load-bearing points.
    • Observe wall construction technique: consistent batter (approx. 1:6 or 1:8 slope), through stones spanning full width at intervals, and avoidance of vertical running joints (overlap joints).
    • Check for structural integrity: wall face should be tight-fitting with no gaps larger than 25mm; hearting (internal fill) must be well packed without voids.
    • Evaluate finishing: capping stones (copes) securely placed, wedged if necessary, with edge projection consistent and aesthetically pleasing, reflecting local walling style.
    • Mark for safe and correct tool use: use of walling hammer for shaping and trimming, use of line and pins for straight runs and batter frames for angle.
    • Award credit for demonstrating accurate foundation preparation: trench dug to a consistent depth below topsoil, base leveled and compacted, with correct width for wall type.
    • Award credit for correct construction technique: stones placed with the longest face into the wall, no vertical joints, adequate batter, and regular use of through-stones for bonding.
    • Award credit for safe and efficient use of tools (e.g., hammer, string line, spirit level) and adherence to PPE requirements throughout the task.
    • Award credit for demonstrating the correct setting out, excavation, and leveling of a foundation trench to the required depth and width, ensuring a firm base free of loose material.
    • Award credit for evidence of appropriate stone selection and placement, including the use of large, stable base stones and through stones to bond the wall thickness.
    • Award credit for constructing a wall with consistent batter (taper), appropriate crown height, and well-packed hearting, resulting in a structurally sound and visually coherent outcome.

    Assessment Guidance

    Guidance for achieving higher grades

    • 💡During practical assessment, start by clearly explaining your approach to site preparation and foundation layout, referencing any given specifications.
    • 💡Systematically sort stones before building: create separate piles for foundation, walling, throughs, and copes to expedite construction and show methodical thinking.
    • 💡Frequently check the batter using a batter frame or template and adjust as you build; assessors look for consistent adherence to the specified angle.
    • 💡Prioritise health and safety: demonstrate correct manual handling (bend knees, keep back straight), wear appropriate PPE (gloves, steel-toe boots, goggles when trimming stone), and ensure a safe workspace free of trip hazards.
    • 💡If required, adapt to local stone type and texture; show an understanding of how the stone’s properties (e.g., layered, rounded) influence building techniques.
    • 💡Regularly step back and inspect your work from a distance to ensure lines are straight and batter is even; this also demonstrates quality control awareness.
    • 💡Practice setting out a string line and batter frame before starting, as precise alignment is critical for assessment grading.
    • 💡Document your work process with annotated photos or a logbook, showing step-by-step decisions on stone selection and bonding patterns.
    • 💡During the assessment, verbally explain why you choose certain stones and how you maintain structural integrity, demonstrating underpinning knowledge.
    • 💡Always use a batter frame or gauge to maintain a consistent wall profile; this is a key indicator of skill and ensures longevity.
    • 💡Take time to select each stone for best fit, turning and positioning them to maximize surface contact and interlock; avoid relying on small packing stones to fill gaps.
    • 💡Demonstrate a clear understanding of health and safety, such as correct manual handling and wearing appropriate PPE, as this forms part of the assessment criteria.
    • 💡When answering questions about habitat management, always link the technique to a specific species or conservation goal. For example, explain that coppicing creates sunny clearings that benefit butterflies like the pearl-bordered fritillary.
    • 💡Use real examples from your work placement to illustrate your answers. Mentioning a specific task you completed, such as building a bird box or clearing a pond, shows practical understanding and earns higher marks.
    • 💡For questions on sustainability, remember to apply the 'three pillars' model: environmental, social, and economic. Even in a Level 1 context, showing awareness that conservation must balance these factors demonstrates deeper thinking.

    Common Mistakes

    Common errors to avoid in your coursework

    • Inadequate foundation depth: not digging down to firm subsoil, leading to settlement and wall collapse over time.
    • Poor stone sorting: using all large stones in lower courses without packing, leaving voids, or placing small stones on the base course causing instability.
    • Ignoring batter: building vertical sections instead of tapering inward, reducing wall strength and encouraging bulging.
    • Running joints: aligning vertical joints in successive courses rather than staggering them, creating continuous lines of weakness.
    • Insufficient hearting: leaving empty spaces inside the wall without small stones to lock the face stones, causing internal shifting.
    • Weak capping: using unstable stones for copes or not securing them, making them vulnerable to dislodging.
    • Building on unlevel ground without adequate foundation, leading to structural instability and wall collapse over time.
    • Selecting poorly shaped stones (rounded or irregular) that do not bed securely, compromising the wall's load-bearing capacity.
    • Forgetting to incorporate through-stones or misaligning them, which weakens the wall's lateral strength.
    • Failing to dig foundations deep enough or onto stable subsoil, leading to settlement and wall collapse.
    • Creating continuous vertical joints by not overlapping stones adequately, which weakens the wall's structural integrity.
    • Using stones that are too small or irregular without sufficient larger stones, resulting in an unstable wall prone to bulging.
    • Misconception: Conservation means leaving nature completely alone. Correction: Active management is often needed to maintain biodiversity, such as grazing to prevent scrub encroachment or controlling invasive species like rhododendron.
    • Misconception: All non-native species are harmful. Correction: Some non-native species are benign or even beneficial (e.g., honeybees in the UK), but invasive non-native species (e.g., Japanese knotweed) cause significant damage. Students should learn to distinguish between them.
    • Misconception: Recycling is the most important environmental action. Correction: While recycling helps, reducing consumption and reusing items have a greater impact. The waste hierarchy (reduce, reuse, recycle) should be prioritised in that order.
