Modification History

ISC upgrade to include new units in Trade Specialisation list. Refer to Mapping of Changes.


This qualification covers the skills and knowledge required to work as an Engineering Tradesperson – Mechanical within metal, engineering, manufacturing and associated industries or other industries where Engineering Tradesperson – Mechanical work. The qualification has been specifically developed for apprentices in the above trade. The qualification packaging has been developed on an assumption that competency will be developed through a combination of on and off-the-job learning strategies such as those delivered through a formal apprenticeship. The qualification may also be achieved through formal skills recognition assessment processes.

Job roles /employment outcome

The Certificate III in Engineering – Mechanical Trade specifies the competencies required for employment as an Engineering Tradesperson – Mechanical including the design, assembly, manufacture, installation, modification, testing, fault finding, commissioning, maintenance and service of all mechanical equipment, machinery, fluid power systems, stationary and mobile equipment, instruments, refrigeration, and the use of computer controlled machine tools.

Employment outcomes related to this qualification are found in a wide variety of manufacturing and engineering related sectors as well as Engineering Tradesperson – Mechanical roles in other industries.


This qualification is designed to provide an industry recognised skills profile related to trade work as an Engineering Tradesperson – Mechanical. Skills development would be undertaken through an Australian Apprenticeship arrangement where the mix of on and off-the-job training would be specified in the Training Plan associated with the Contract of Training between the employer and apprentice.

Assessment of some units of competency must, where indicated, include evidence of the candidate’s performance in a productive work environment where there is a sufficient range of appropriate tasks and materials to cover the scope of application of those units. All outcomes must reflect the standard of performance inherent in the job. Occupational titles that this qualification is suitable for may vary and include mechanical tradesperson, fitter and turner, fitter and machinist, maintenance fitter, diesel fitter, plant mechanic, refrigeration mechanic and 1st class machinist.

Additional qualification advice

An additional descriptor may be added to this qualification to illustrate a particular skills focus or trade discipline. This could be achieved by adding a pathway descriptor or sentence below the formal title of the qualification. Note that no changes may be made to the qualification title and the use of one of these descriptors to a qualification does not change the qualification’s formal title or unique national code. There are no specific requirements associated with the use of these descriptors other than their use should reflect the nature of the choice of units of competency in the qualification and must be consistent with the work role of an Engineering Tradesperson – Mechanical.

Reference to other occupational or functional pathways consistent with the role of an Engineering Tradesperson – Mechanical may be included on any qualification statement that is issued. Competitive Manufacturing qualifications are available for employees at this level who already possess trade and other technical skills and who require additional manufacturing practice skills above those available in this qualification.

Licensing considerations

There are no specific licences that relate to this qualification. However, some units in this qualification may relate to licensing or regulatory requirements. Where appropriate electives are taken these can also be used to satisfy regulations regarding refrigeration and air conditioning work. Local regulations should be checked for details.
