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.
Irrigation plans may include:
plans for low volume, sprinkler and surface irrigation systems that may cover water supply, distribution, conveyancing and drainage.
Irrigation drawings
drawings may be part of the irrigation plan and cover the range of irrigation components (hardware) and structures (earthworks) used in commercial irrigation.

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:
interpret symbols and abbreviations on plans
orientate a site plan for an irrigation system
mark out boundaries and features on a site from irrigation installation plans and drawings
list the irrigation components required for installation from a plan.
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.
