    UNIT STANDARD ACCREDITATION AND MODERATION OPTIONS 
    My assessment will be governed by the policies and guidelines of the MERSETA Education and Training Quality Assurer who has jurisdiction over this field of learning. My assessor will (at the very least) be accredited and have a technical qualification in this learning area.

    I can be assessed in the language of my choice although if I have to report incidents or conditions to someone else, I will be assessed on my ability to report in the language commonly used in my working environment.

    I will be assessed in the workplace but I can submit documents, projects, test results and assignments that were not produced in the workplace.

    I can be assessed against this unit standard to obtain credits or as part of an integrated assessment for a qualification.
