Evidence Required

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 and evidence required to demonstrate competency in this Unit	The evidence required to demonstrate competency in this Unit must be relevant to workplace operations and satisfy holistically all of the requirements of the performance criteria and required skills and knowledge and include achievement of the following inspect moving sprinkler irrigation systems maintain irrigation equipment troubleshoot and undertake minor repairs of equipment record and report maintenance activities dispose of unused or waste materials from site
Context of and specific resources for assessment	Competency requires the application of work practices under work conditions Selection and use of resources for some worksites may differ due to the regional or enterprise circumstances

Range Statement

The range statement relates to the Unit of Competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.
Moving sprinkler irrigation systems may include:	any systems that use specifically hard and soft reel self-travelling irrigators, lateral move systems and centre pivots. Moving sprinkler systems do not include movable sprinkler systems such as K-Line.
System components may include:	pipes joints valves sprinklers Vjack trusses span pipes pressure regulators hose directors gear box control panel wheels.
