EVIDENCE GUIDE
The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.
Overview of assessment

Critical aspects for assessment evidence required to demonstrate competence in this unit
Assessment must confirm the ability to:
maintain and repair water supply and disposal systems and structures, including safely shutting down and restarting water supply and disposal systems and structures with minimal stress or damage to stock.

Assessment must confirm knowledge of:
general maintenance requirements for specific water supply and disposal systems or structures
safe work practices
techniques appropriate for the maintenance and repairs being undertaken.
Context of and specific resources for assessment
Assessment is to be conducted at the workplace or in a simulated work environment, maintaining and making minor repairs to pumps, aerators and filters typically used in aquaculture enterprises in the region.

Resources may include:
hand and power tools and parts relevant to the water supply and disposal system or structure
maintenance schedule and enterprise procedures
manufacturer operation and service manuals
water supply and disposal system or structure.
Method of assessment
The following assessment methods are suggested:
demonstration
practical exercises
project work
written or oral short-answer testing.
Guidance information for assessment
