    UNIT STANDARD ACCREDITATION AND MODERATION OPTIONS 
    1. Anyone assessing a learner against this unit standard must be registered as an assessor with the relevant ETQA.
    2. Any institution offering learning that will enable achievement of this unit standard must be accredited as a provider through the relevant ETQA.
    3. Moderation of assessment will be overseen by the relevant ETQA according to the moderation guidelines in the relevant qualification and the agreed ETQA procedures.

    The assessment of qualifying learners against this standard should meet the requirements of established principles. Practical assessment activities will be used, which are appropriate to the contents in which qualifying learners are working. These activities will include an appropriate combination of self and peer assessment, practical and oral assessments, observations etc.

    The assessment should ensure that all the specific outcomes, critical cross-field outcomes and essential embedded knowledge be assessed. The specific outcomes must be assessed in its own right, through oral and practical evidence. It cannot be assessed by observation only.

    The specific outcomes and essential knowledge must be assessed in relation to each other. If a qualifying learner is able to explain the essential embedded knowledge, but is unable to perform the specific outcomes, then they should not be assessed as competent. Similarly, if a learner is able to perform specific outcomes, but is unable to explain or justify their performance in terms of the essential embedded knowledge, they should not be assessed as competent.

    Evidence of the specified critical cross-field outcomes should be found, both in performance and in the essential embedded knowledge.

    Performance of specific outcomes must actively affirm target groups of qualifying learners, not unfairly discriminate against them. Qualifying learners should be able to justify their performance in terms of these values.
