Assessment Conditions

Competency is to be assessed in the workplace or a simulated environment that accurately reflects performance in a real workplace setting.

Assessment must include direct observation of tasks.

Where assessment of competency includes third-party evidence, individuals must provide evidence that links them to the hydraulic systems that they have worked on, e.g. repair orders.

Assessors must verify performance evidence through questioning on skills and knowledge to ensure correct interpretation and application.

The following resources must be made available:

automotive repair workplace or simulated workplace

workplace instructions

manufacturer hydraulic system specifications

two hydraulic systems with faults in the components specified in the performance evidence

diagnostic tools and equipment for hydraulic systems, including pressure gauges or flow meters

AS 1101.1 Graphic symbols for general engineering, Part 1: Hydraulic and pneumatic systems

tools, equipment and materials appropriate for repairing and adjusting hydraulic systems.

Assessors of this unit must satisfy the requirements for assessors in applicable vocational education and training legislation, frameworks and/or standards.
