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

develop maintenance procedures

supervise maintenance of irrigation components and testing equipment

supervise maintenance of irrigation structures

supervise maintenance of the irrigation area

record and report maintenance activities

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.

Maintenance programs may include:

preventative maintenance carried out at end of season or throughout the irrigation season, including the regular replacement of irrigation components.

Sprinkler irrigation systems may include:

describe systems that use spray or rotor type sprinklers to distribute irrigation water at higher volume including pop-up sprinklers, fixed, and movable sprinklers (e.g. K Line and Ezy Shift).

Maintenance of testing equipment may include:

replacing 'remove and replace' components; lubrication; working adjustments to tolerances; cleaning and storing; and completing usage records.
