UNIT STANDARD ACCREDITATION AND MODERATION OPTIONS

The assessment will be governed by the policies and guidelines of the MERSETA Education and Training Quality Assuror (ETQA) who has jurisdiction over this field of learning. The assessor will (at the very least) be accredited and have a technical qualification in this learning area. The learner can be assessed in the language of his/her choice although if s/he has to report incidents or conditions to some one else, s/he will be assessed on his/her ability to report in the language commonly used in the working environment. The learner will be in assessed in the workplace, or by simulation but can submit documents, projects, test results and assignments that are not produced in the workplace or by the RPL process. The learner can be assessed against this unit standard to obtain credits or as part of an integrated assessment for a qualification.
