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.

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.
