  • UNIT STANDARD ACCREDITATION AND MODERATION OPTIONS 
    Accreditation for this Unit Standard shall be obtained from the relevant Education and Training Quality Assurance Body, through summative and formative assessment by a registered assessor.
  • Assessors must be registered as an Assessor with the relevant ETQA, or with an ETQA that has a Memorandum of Agreement with the relevant ETQA.
  • Moderators must be registered as assessors with the relevant ETQA, or with an ETQA that has a Memorandum of Agreement with the relevant ETQA.
  • Training providers must be accredited by the relevant ETQA or with an ETQA that has a Memorandum of Agreement with the relevant ETQA.

    Moderation should include both internal and external moderation where applicable.

    The assessment of qualifying learners against this standard should meet the requirements of established assessment principles.

    It will be necessary to develop assessment activities and tools, which are appropriate to the contexts in which qualifying learners are working. These activities and tools may include an appropriate combination of self-assessment and peer assessment, formative and summative assessment, portfolios and observations etc.

    The assessment should ensure that all the specific outcomes, critical cross-field outcomes and essential embedded knowledge are assessed.

    The specific outcomes must be assessed through observation of performance Supporting evidence should be used to prove competence of specific outcomes only when they are not clearly seen in the actual performance.

    Essential embedded knowledge must be assessed in its own right, through oral and written evidence and cannot be assessed only by being observed.

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

    PROVIDERS CURRENTLY ACCREDITED TO OFFER THIS UNIT STANDARD: 
    This information shows the current accreditations (i.e. those not past their accreditation end dates), and is the most complete record available to SAQA as of today. Some Primary or Delegated Quality Assurance Functionaries have a lag in their recording systems for provider accreditation, in turn leading to a lag in notifying SAQA of all the providers that they have accredited to offer qualifications and unit standards, as well as any extensions to accreditation end dates. The relevant Primary or Delegated Quality Assurance Functionary should be notified if a record appears to be missing from here.
