Elements and Performance Criteria Pre-Content

Elements describe the essential outcomes of a unit of competency.

Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold italicised text is used, further information is detailed in the required skills and knowledge section and the range statement. Assessment of performance is to be consistent with the evidence guide.

Elements and Performance Criteria



1. Prepare netting material for repair

1.1. Netting material  is arranged and repair tools  organised to maximise job efficiency  and safety.

1.2. Material required for the repair operation  is identified by measuring  existing material or by reference to a gear plan.

1.3. Damaged netting is removed using net work tools and disposed of correctly.

1.4. Retained netting is prepared  ready to accept replacement.

1.5. Replacement netting is shaped  with net repair tools.

1.6. Replacement netting is strengthened  according to the gear plan or supervisor's instructions before being added to the net.

2. Mend holes and rips using twine

2.1. Starting points are identified and twine is secured  to the netting according to supervisor's instructions.

2.2. Twine is used to tie knots  that make meshes to resemble original netting .

2.3. Twine is secured at the end of the repair according to supervisor's instructions.

3. Mend large scale damage using netting material

3.1. Starting points are identified and twine is secured to the netting according to supervisor's instructions.

3.2. Existing and replacement material is joined  using twine and knots to resemble original netting.

3.3. Existing and replacement material is joined using twine and lacing  to resemble original netting.

Overview of assessment 

Critical aspects for assessment evidence required to demonstrate competence in this unit 

Assessment must confirm the ability to:

  • mend damage to hung areas of netting
  • mend rips in netting
  • repair large scale damage to netting material by sewing in patches and panels
  • repair various types of damage that occurs to the netting material used for fish or prawn trawls, purse seines, beach seines or gill nets.

Assessment must confirm knowledge of:

  • how a gear plan describes a net.

Context of and specific resources for assessment 

Assessment is to be conducted at the workplace or in a simulated work environment.

Resources may include:

  • different types of netting requiring repair
  • fully operational net repair area.

Method of assessment 

The following assessment methods are suggested:

  • observation of practical demonstration
  • practical exercises
  • project work
  • written or oral short-answer testing.

Guidance information for assessment 

This unit may be assessed holistically with other units within a qualification.
