Assessment Criteria
Key criteria assessors look for in your portfolio
- Assessor should award credit for correctly interpreting job specifications, including tile type, pattern, and starting point.
- Evidence must show identification and safe handling of tools such as trowels, spirit levels, tile cutters, and spacers.
- Marks available for demonstrating appropriate substrate preparation, e.g., cleaning, priming, and applying background treatments.
- Look for accurate setting out: use of datum lines, checking for square, and planning cuts to avoid narrow slivers.
- Credit for consistent tile alignment with correct spacing, level, and plumb, within tolerance limits (±2mm over 2m).
- Assess that adhesive is applied evenly with correct coverage, and tiles are firmly bedded.
- Check that grout joints are full, smooth, and cleaned without residue, and that final surface is free of defects.
- Evidence of post-installation checks and rectification, such as replacing chipped tiles or cleaning grout haze.
- Award credit for correctly interpreting symbols and dimensions from drawings to plan tile layout.
- Check that the learner identifies correct tools (e.g., notched trowel, tile cutter) and explains their use.
- Observe thorough surface preparation: cleaning, filling cracks, applying primer, and checking for level.
- Assess accuracy of datum lines and layout marks using spirit level and measuring tape.
- Evaluate tile fixing technique: even adhesive ridges, full bed coverage, consistent joint width, and tiles flush to plane.
- Inspect completed work for cleanliness, joint sealing integrity, and alignment with specifications.
Assessment Guidance
Guidance for achieving higher grades
- 💡Always double-check measurements and reference points before committing to the first tile; a small error early on can propagate.
- 💡Practise setting out using a gauge rod or story pole to quickly verify tile ranges and cut sizes.
- 💡Document every stage of your work with clear before, during, and after photographs—this is crucial for portfolio evidence.
- 💡When using patterned tiles, check for directional arrows and batch consistency to avoid mismatches.
- 💡Familiarise yourself with the specific tolerances and acceptance criteria detailed in BS 5385 (Wall and floor tiling) for this qualification.
- 💡For assessments, narrate your process as you work, explaining why you are taking each step to demonstrate understanding.
- 💡Always refer to manufacturer's instructions for adhesive mixing ratios and open times.
- 💡Use a spirit level and plumb line frequently during setting out to maintain accuracy.
- 💡Photograph key stages of your setting out and tiling for portfolio evidence; annotate to show decisions.
- 💡Check your work against the original specification and quality standards at each stage, not just at the end.
- 💡In practical assessments, always demonstrate your setting-out process clearly. Examiners award marks for showing you can plan a layout to minimise cuts and achieve balanced borders, not just for the final appearance.
- 💡When answering theory questions, use technical terminology correctly (e.g., 'substrate' not 'wall', 'notched trowel' not 'spreader'). This shows depth of knowledge and can push you into higher mark bands.
- 💡For written exams, remember to reference relevant British Standards (e.g., BS 5385 for wall and floor tiling) and health and safety regulations (e.g., COSHH for adhesives). This demonstrates awareness of industry compliance.
Common Mistakes
Common errors to avoid in your coursework
- Misreading dimensions or tile offsets from drawings, leading to incorrect layout and excessive cutting.
- Forgetting to allow for expansion joints or perimeter movement joints, causing subsequent cracking.
- Using the wrong adhesive for the substrate (e.g., using cement-based adhesive on wooden surfaces without additives).
- Overloading the trowel with adhesive and not achieving full coverage, resulting in hollow-sounding tiles.
- Applying grout too early before adhesive has set, causing tile movement.
- Neglecting to clean tiles before grouting, leading to staining.
- Not establishing true level datum lines, leading to uneven tile courses or cuts.
- Using incorrect adhesive for the substrate or tile material, causing debonding.
- Neglecting to dry-lay tiles before fixing to identify layout issues and minimize cuts.
- Inadequate surface preparation, such as failing to remove dust or address moisture, resulting in poor adhesion.
- Forgetting to leave expansion joints or movement gaps around perimeters.
- Myth: 'Any adhesive works for all tiles.' Correction: Large-format or porcelain tiles require specific adhesives with higher bond strength and slip resistance; using the wrong adhesive can lead to tiles debonding or cracking.
- Myth: 'Grout is just for filling gaps.' Correction: Grout also provides structural support, prevents water ingress, and accommodates minor movement. Improper mixing or application can cause cracking, staining, or mould growth.
- Myth: 'Tiles don't need expansion joints.' Correction: All tiled areas require movement joints at perimeters and intermediate points (every 8-10m² indoors) to allow for thermal expansion and prevent tenting or cracking.
