Student Assessment Guide
Competency Name: Verify compliance and functionality of appliances
Competency Code: J109A
Competency Purpose:
This competency provides the methods and criteria for ensuring a person has achieved the levels of performance in the critical skills related to the installation, maintenance, repair , fault finding, testing and commissioning of refrigeration, air-conditioning and appliances . This competency shall be undertaken only after the successful completion of all underpinning curriculum knowledge and skills, and the work performance reports for all competency units in the Certificate III Electrotechnology appliance servicing , indicate that relevant work is routinely being carried out autonomously and to requirements.
Competency Assessment:
The assessment for this competency is graded and is recorded as PASS or FAIL. A ‘FAIL’ will be awarded to students that:
- are deemed ‘not yet competent’ by the supervisor,
