Each unit of competency has an evidence guide that relates directly to the performance criteria and the range of variables. Its purpose is to guide assessment of the unit in the workplace and/or training program. The following components provide information to assist this purpose.

Underpinning knowledge
The essential knowledge and understanding a person needs to perform work to the required standard include:
· tools required for maintenance and repair
· techniques to repair or maintain structures
· enterprise OHS guidelines and procedures.

Practical skills
The essential skills a person needs to perform work to the required standard include:
· assessing and reporting on extent and urgency of required repairs and maintenance
· using a range of workshop, hand and power tools.

Literacy skills used for:
· reading warning signs and/or labels on tools or products.

Numeracy skills used for:
· measuring quantities.

Critical aspects of competence
Assessment must confirm the ability to:
· identify the need for and carry out basic maintenance and repair work on stock culture structures, farm structures and fittings and fixtures in an aquaculture enterprise.
Assessment must confirm knowledge of:
· basic repair and maintenance techniques or SOPs relevant to stock and farm structures.

Interdependent assessment of units
This unit may be assessed after/with:
· SFIAQUA211B - Undertake routine maintenance of water supply and disposal systems and structures.

Context of assessment
Assessment is to be conducted at the workplace or in a simulated work environment. It should cover the basic maintenance and repairs typically required in an aquaculture facility in the region.

Method of assessment
The following assessment methods are suggested:
· practical exercises
· observation of practical demonstration.

Resources required for assessment
Resources may include:
· stock culture structures, farm structures and areas of property in need of maintenance
· tools and repair materials
· SOPs for repairs and maintenance.
