    Assessment Criteria

    Key criteria assessors look for in your portfolio

    • Award credit for demonstrating the correct selection of numeracy skills (e.g., using division to calculate product dilution ratios) in a given work scenario.
    • Evidence must show accurate application of numeracy skills, such as correctly working out total service time including processing and development periods.
    • Learners should present and interpret results (e.g., recording measurements or costs) clearly in a work-relevant format, like a client record card or order form.
    • Award credit for accurately calculating the correct ratio of developer to tint for a client’s hair color service, demonstrating understanding of volumetric measures.
    • Award credit for correctly using a pricing chart to determine the total cost of multiple services and applying discounts or promotions, showing applied arithmetic.
    • Award credit for clearly explaining the numerical results to a client, such as the breakdown of charges or the timing steps for a treatment, using appropriate terminology.
    • Award credit for correctly selecting and using appropriate measuring tools (e.g., scales, measuring jugs, colour charts) in practical tasks.
    • Evidence must demonstrate accurate calculation of product ratios (e.g., 1:1, 1:2) when mixing tints, developers, or other treatments.
    • Assessor should observe clear interpretation and verbal communication of numerical results to clients or colleagues, such as confirming treatment costs or timings.
    • Written work must show logical steps when solving work-based numerical problems, including correct units and labelling.
    • Practical simulations must include accurate handling of money, giving change, and processing card payments as per salon procedures.

    Assessment Guidance

    Guidance for achieving higher grades

    • 💡Always double-check the units required on product instructions before performing calculations.
    • 💡In time management tasks, create a simple timeline or list to ensure all steps are accounted for.
    • 💡For money calculations, practise using the salon price list to give correct change, including scenarios with discounts or add-ons.
    • 💡For practical assessments, always verbally narrate your calculations while performing tasks to demonstrate your thought process to the assessor.
    • 💡In written assignments, show all working out clearly, even for simple calculations, to gain full marks for method.
    • 💡Double-check unit conversions (e.g., ml to litres) by cross-referencing with typical product packaging to catch common errors.
    • 💡In practical assessments, verbalise your numerical reasoning as you work to demonstrate underpinning knowledge.
    • 💡Always show your calculations clearly in written assignments; even if the final answer is wrong, method marks may be awarded.
    • 💡Familiarise yourself with common product ratios and treatment timings specific to your salon's brands before assessment.
    • 💡For role-play scenarios, practise articulating costs, timings, and aftercare advice numerically to build confidence.
    • 💡Always follow the order of a treatment: prepare your workstation, consult the client, perform the treatment, and clean up. Examiners look for this systematic approach.
    • 💡When answering written questions, use key terms like 'hygiene', 'contra-indications', and 'client care'. This shows you understand the theory behind the practice.
    • 💡In practical assessments, talk through what you are doing. For example, say 'I am now applying shampoo using circular motions to stimulate the scalp.' This demonstrates your knowledge and confidence.

    Common Mistakes

    Common errors to avoid in your coursework

    • Misreading product labels, leading to incorrect mixing ratios (e.g., confusing 1:2 with 2:1).
    • Miscalculating total appointment time by omitting preparation and clean-up minutes.
    • Rounding measurements incorrectly when converting between units (e.g., millilitres to litres).
    • Confusing volume (ml) and weight (grams) when measuring products, leading to incorrect mixtures.
    • Misinterpreting decimal time (e.g., thinking 0.5 hours is 50 minutes rather than 30 minutes) when scheduling appointments.
    • Applying a percentage discount by dividing by the percentage rather than multiplying by the decimal equivalent.
    • Misreading ml and g scales on measuring equipment, leading to incorrect product quantities.
    • Confusing percentage strengths when mixing developers, e.g., using 6% instead of 9%.
    • Incorrectly rounding up or down when calculating service times, causing booking overlaps or under-timing.
    • Forgetting to double-check totals and change when handling cash transactions, resulting in till discrepancies.
    • Misconception: 'You don't need to wear gloves when applying hair colour.' Correction: Always wear gloves to protect your skin from chemicals and prevent allergic reactions. This is a key health and safety rule.
    • Misconception: 'Client consultation is just a chat.' Correction: It is a formal process to gather important information. Skipping it can lead to allergic reactions or unsatisfactory results. Always record details on a consultation card.
    • Misconception: 'Any shampoo works for all hair types.' Correction: Different shampoos are formulated for specific needs (e.g., dry, oily, coloured hair). Using the wrong one can damage hair or cause scalp issues.
