    Assessment Criteria

    Key criteria assessors look for in your portfolio

    • Award credit for accurately adding two or more whole numbers in a work-based scenario (e.g., totalling items on an invoice).
    • Award credit for correctly subtracting one whole number from another, demonstrating understanding of 'taking away' in a practical context (e.g., determining change from a purchase).

    Assessment Guidance

    Guidance for achieving higher grades

    • 💡Always read the problem carefully to identify whether addition or subtraction is required before starting any calculation.
    • 💡When using a calculator, perform a rough estimate in your head to check if the displayed answer is reasonable.
    • 💡For written assessments, show all working steps clearly—this can earn marks even if the final answer is incorrect due to a small slip.
    • 💡Practise with real-life employability tasks such as stocktaking, shopping lists, or timesheet calculations to build confidence.
    • 💡Tip 1: Always read instructions carefully. In assessments, many marks are lost because students don't follow the task requirements exactly. Take your time to understand what is being asked.
    • 💡Tip 2: Use examples from your own experience. When answering questions about teamwork or problem-solving, think of a real situation you've been in and explain what you did. This shows you can apply the skills.

    Common Mistakes

    Common errors to avoid in your coursework

    • Misaligning digits when using column addition or subtraction, leading to place value errors.
    • Forgetting to 'carry' or 'borrow' correctly, especially when zeros are involved.
    • Confusing addition and subtraction when interpreting word problems (e.g., adding instead of subtracting to find a difference).
    • Relying solely on a calculator without estimating the answer first, making it harder to spot keying errors.
    • Misconception: 'Employability skills are just common sense, so I don't need to study them.' Correction: While some skills may seem obvious, the diploma teaches you how to apply them in a structured, professional way that employers expect.
    • Misconception: 'Teamwork means I have to do everything the group says.' Correction: Good teamwork involves sharing ideas, listening, and contributing, not just following others. You should also know when to speak up.
