Assessment Criteria
Key criteria assessors look for in your portfolio
- Award credit for demonstrating thorough preparation, including conducting a risk assessment for the specific glazed surface, identifying hazards (e.g., working at height, fragile glass), and selecting appropriate protective equipment and signage.
- Award credit for correctly carrying out the cleaning process using industry-standard techniques, such as the straight-pull or fanning method with a squeegee, ensuring complete removal of dirt and cleaning solution without leaving streaks or residue.
- Award credit for systematically checking all cleaned areas for smears, spots, or missed patches, and addressing any issues before final sign-off, including the proper disposal of waste water and used materials.
- Award credit for safely returning and storing all equipment, such as extension poles, ladders, and cleaning tools, and ensuring that chemicals are securely locked away, with any damaged items reported according to workplace procedures.
Assessment Guidance
Guidance for achieving higher grades
- 💡Always begin by clearly outlining your risk assessment and method statement, as this demonstrates a professional approach and meets health and safety criteria.
- 💡When performing practical tasks, narrate your actions to the assessor to explain why you are using particular techniques or products, ensuring they capture your reasoning.
- 💡Ensure your evidence portfolio includes photographs of completed work, showing streak-free finishes, and signed witness testimonies to validate your competence.
- 💡Practice the squeegee technique repeatedly to build muscle memory; a common failure is leaving a wet edge that dries into a visible line, which assessors will look for.
- 💡Before finishing, carry out a thorough inspection against a checklist, and document any corrective actions taken, as this shows quality control awareness.
- 💡Always use the correct terminology, such as 'sanitise', 'disinfect', 'contact time', and 'risk assessment', to show your understanding.
- 💡When answering questions about procedures, structure your answer logically: preparation, action, and aftercare.
- 💡Read the question carefully to identify the command word (e.g., 'explain', 'state', 'describe') and tailor your response accordingly.
Common Mistakes
Common errors to avoid in your coursework
- Using excessive water or cleaning solution, which leads to drips and streaks, especially on vertical glazed surfaces.
- Failing to protect surrounding areas (e.g., floors, furniture) from splashes, resulting in slip hazards or damage.
- Incorrect squeegee blade angle or pressure, causing uneven cleaning and leaving water marks.
- Neglecting to check for and remove all waste, such as used cloths or empty chemical containers, leaving the worksite untidy.
- Not completing equipment checks upon return, such as failing to wipe down and inspect items for damage before storage.
- Misconception: 'More chemical means better cleaning.' Correction: Using too much chemical can leave residues, be wasteful, and may be hazardous. Always follow dilution instructions.
- Misconception: 'Disinfectants work instantly.' Correction: Disinfectants require a specific contact time to be effective; wiping off immediately reduces their efficacy.
- Misconception: 'Cleaning and disinfecting are the same.' Correction: Cleaning removes dirt and some germs, but disinfecting kills germs; both are necessary for hygiene.

Step-by-Step Worked Solutions
Detailed solution breakdown for typical exam problems
Question: A cleaning operative is preparing a disinfectant solution. The label states a dilution rate of 1:100 (1 part chemical to 100 parts water). They need to make 5 litres of solution. How much chemical and how much water should they use? Show your working.
- 1.Step 1: Identify the total volume needed: 5 litres = 5000 ml.
- 2.Step 2: The dilution ratio 1:100 means 1 part chemical + 100 parts water = 101 parts total.
- 3.Step 3: Calculate the volume of chemical: (1/101) × 5000 ml = 49.5 ml (approximately).
- 4.Step 4: Calculate the volume of water: (100/101) × 5000 ml = 4950.5 ml (or subtract chemical from total: 5000 - 49.5 = 4950.5 ml).
- 5.Step 5: State the final answer with units.
Question: Explain the difference between cleaning, sanitising, and disinfecting, and give one example of when each is used in a healthcare setting.
- 1.Step 1: Define cleaning: removal of visible dirt and organic matter using detergent and water.
- 2.Step 2: Define sanitising: reducing microorganisms to safe levels, often using heat or chemicals, e.g., food contact surfaces.
- 3.Step 3: Define disinfecting: destroying harmful microorganisms using chemicals, with a specified contact time, e.g., bathroom surfaces.
- 4.Step 4: Provide examples: cleaning – daily floor mopping; sanitising – wiping down food preparation areas; disinfecting – cleaning toilet bowls or clinical surfaces.
- 5.Step 5: Conclude with the importance of following the correct sequence: clean first, then sanitise/disinfect.
