PURPOSE OF THE UNIT STANDARD

The skills, values and knowledge reflected in this unit standard are required for the people in the field of autotronics.

The learning outcomes of this unit standard also contribute to the exit levels outcomes required for the autotronics NQF 4 level qualification.

Qualifying learners are able to trace and repair advanced auto-electrical circuits on an automobile from circuit diagrams, per instruction, in accordance to procedure, and/or with the aid of manufacturers service manuals in a safe and aware manner.

LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING

This unit standard is designed as part of a progression.

The credits allocated to this unit standard assume that the learner is competent on the relevant unit standards at the lower level, including:

Trace and repair auto-electrical circuits on automobiles

The credits allocated to this unit standard assumes that a learner has already learnt to:

Fit and wire up auxiliary auto electrical equipment

UNIT STANDARD RANGE

The scope and level of this unit standard is determined by the ranges as indicated under specific outcomes.

The learner should be able to work autonomously.

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.
