    Assessment Criteria

    Key criteria assessors look for in your portfolio

    • Award credit for demonstrating consistent blade tension throughout the task, evidenced by clean entry and exit cuts
    • Look for minimal deviation from scribed or glued template lines, within ±0.2 mm tolerance
    • Credit should be given when the learner uses appropriate support (e.g. bench peg, v-block) to prevent workpiece flex and breakage
    • Examiners should reward effective lubrication technique that reduces friction and prolongs blade life
    • Marks for safely removing and re-inserting the blade for internal piercing, with no damage to the cut surface
    • Assess the final component edges for perpendicularity, absence of burrs, and readiness for subsequent fitting processes
    • Award credit for demonstrating correct blade selection based on metal thickness and desired kerf width, with the saw blade teeth pointing towards the handle.
    • Expect the workpiece to be securely supported on a bench peg with the cutting line clearly visible and the saw held perpendicular to the metal surface throughout.
    • Credit should be given for smooth, continuous cuts that follow the design accurately without excessive deviation, evidenced by minimal blade breakage and clean edges requiring little remedial filing.
    • For piercing operations, expect evidence of correctly drilled pilot holes of appropriate size to allow blade insertion, positioned entirely within the waste material.
    • Assessors should look for proper sawing posture and technique, including relaxed grip, straight arm movement, and consistent, controlled cutting speed that avoids forcing the blade.
    • Award credit for demonstrating correct setup and tensioning of a jeweller's saw frame, tailored to the material thickness and complexity of the design.
    • Expect evidence of selecting and using appropriate saw blade grades (e.g., 4/0, 6/0) for intricate piercing, with justification linked to the component's requirements.
    • Look for clear transfer of a complex design onto silver sheet (e.g., via adhesive templates or engraving), with piercings executed accurately along marked lines.
    • Assess the finish quality of sawn edges: they should be square, smooth, and free from burrs, undercutting, or wandering from the design line.
    • Evidence should include safe working practices, such as securing the workpiece with a bench peg or clamp, and using lubrication (e.g., beeswax) to prolong blade life.
    • Award credit for demonstrating correct selection of saw blade size and tooth configuration relative to metal thickness
    • Expect evidence of proper blade tensioning and secure workholding to enable accurate cutting
    • Look for clean, continuous cuts that closely follow the design line with minimal wandering
    • Assess internal piercing starts with a drilled pilot hole and proceeds with controlled strokes
    • Credit finishing techniques such as filing or sanding sawn edges to remove burrs and achieve a smooth profile

    Assessment Guidance

    Guidance for achieving higher grades

    • 💡Prioritise a stable workpiece setup: clamp or adhere the silver to a wooden block when making intricate internal cuts to minimise vibration
    • 💡Practise piercing scrap material first to confirm blade choice and tension, reducing risk on assessed components
    • 💡Plan the sequence of cuts to avoid isolated sections becoming difficult to hold – leave bridging tabs that can be cut last and easily separated
    • 💡For assessed portfolios, photograph and annotate each stage, clearly explaining decisions on blade grade, lubricant, and corrective actions taken
    • 💡Always start by ensuring the saw frame is correctly adjusted to the blade length with a clear 'ping' sound when plucked, indicating proper tension.
    • 💡Use a beeswax or appropriate lubricant frequently during cutting to reduce friction and prolong blade life, especially on thicker silver.
    • 💡For complex piercings, drill relief holes at tight internal corners and use a series of smaller cuts to navigate sharp angles without blade strain.
    • 💡In assessments, prioritise accuracy and edge finish over speed; evidence of careful, controlled sawing earns higher marks than rushed, imprecise work.
    • 💡Practice tracing the design multiple times with the saw before cutting into the metal, and keep the blade moving with a steady up-and-down motion, allowing the teeth to do the work.
    • 💡Always demonstrate blade selection and tension setting to the assessor, clearly explaining your choices—this shows underpinning knowledge.
    • 💡When presenting coursework, include photographs or videos of your piercing process at key stages, annotated with explanatory notes to evidence understanding.
    • 💡For complex internal piercings, plan the sequence of cuts in advance and document your approach to show methodical problem-solving.
    • 💡In practical assessments, prioritize accuracy over speed; re-cut if necessary, but explain any corrections as part of reflective practice.
    • 💡Keep a log of blade breakages and the reasons for them—turning a mistake into a learning point can positively influence the assessor's judgment of your competence.
    • 💡Practice maintaining a steady, vertical sawing posture with the blade perpendicular to the work surface
    • 💡Always mark out designs clearly with a scriber and centre punch drill points for internal piercing
    • 💡Begin external cuts from a corner or notch to establish an accurate starting groove
    • 💡Keep a record of blade types, sizes, and materials used for each component to demonstrate technical understanding
    • 💡Allow time for finishing processes; assessors value components that are ready for the next production stage
    • 💡Always check your tool sharpness before starting; dull burs or gravers can slip and damage stones or metal, costing marks in precision.
    • 💡Document each step with clear photographs and annotations in your portfolio; examiners look for evidence of planning, problem-solving, and reflection on outcomes.
    • 💡Practice setting stones in scrap metal before working on final pieces; this builds muscle memory and reduces waste, demonstrating efficiency and skill development.

    Common Mistakes

    Common errors to avoid in your coursework

    • Applying excessive feed pressure causing blade deflection and angled cuts
    • Neglecting to use a backing board or sacrificial surface when piercing, leading to breakout on the exit side
    • Failing to regularly rotate or replace blades as they dull, resulting in rough or melted edges (especially in thicker stock)
    • Misaligning the saw frame during tight turns, causing the blade to bind or snap
    • Incorrect blade selection – using too coarse a blade for thin material, or too fine for thick, each causing poor cut quality
    • Students often select a blade with too few teeth per inch for thin silver sheet, causing the metal to catch and tear rather than cut cleanly.
    • A frequent error is applying excessive forward pressure, which leads to blade buckling, breakage, and wandering off the intended line.
    • Incorrect blade tensioning, either too loose causing the blade to veer or too tight leading to premature snapping, compromises cut quality.
    • Many learners fail to lubricate the blade adequately, resulting in heat build-up, galling of the silver, and accelerated blade wear.
    • When piercing, neglecting to support the workpiece and instead holding it mid-air often causes distortion of the metal or snapping of fine sections.
    • Applying excessive forward pressure, which bends or snaps the blade, rather than letting the saw teeth do the cutting with light, rhythmic strokes.
    • Failing to release tension on the saw frame after use, which weakens the blade and distorts the frame over time.
    • Starting an internal piercing without a properly drilled pilot hole, leading to blade breakage or inaccurate entry points.
    • Neglecting to frequently check that the saw blade remains perpendicular to the workpiece, resulting in tapered or uneven cuts.
    • Using a blade with too few or too many teeth per inch for the material thickness, causing rough cuts or blade clogging.
    • Applying excessive feed pressure, causing blade breakage or distorted cuts
    • Neglecting blade lubrication, leading to increased friction and poor cut quality
    • Failing to support thin sheet adequately, resulting in bending or tearing during piercing
    • Incorrect blade tension – too loose causes wandering, too tight leads to premature breakage
    • Omitting pilot holes for internal piercing, which risks blade damage and inaccurate shapes
    • Misconception: Any stone can be set using the same technique. Correction: Stones vary in hardness, brittleness, and shape; for example, opals are too soft for pavé setting, while diamonds can withstand claw setting pressure.
    • Misconception: More metal around the stone means better security. Correction: Overly thick bezels or claws can obscure the stone and reduce light entry, diminishing brilliance; the goal is minimal metal with maximum grip.
    • Misconception: Soldering is always done before setting. Correction: Some settings (e.g., channel) require stones to be placed before final soldering to avoid heat damage; sequence depends on the technique and metal.
