Application
This unit of competency describes the skills and knowledge required to generate tree plans using computer-aided design software.
This unit applies to individuals who take personal responsibility and exercise autonomy in undertaking complex work, to analyse and synthesise information and design, and to communicate solutions to complex problems. Work is performed in accordance with Australian Standards and industry drawing protocols.
No occupational licensing, legislative or certification requirements are known to apply to this unit at the time of publication.

Assessment Conditions
Assessment must be demonstrated consistently over time in a suitable range of contexts and have a productivity-based outcome. No single assessment event or report is sufficient to achieve competency in this unit.
Assessment may be conducted in a simulated or real work environment, however determination of competency requires the application of work practices under work conditions.
The mandatory equipment and materials used to gather evidence for assessment include:
equipment:
computer
word processing software
CAD software
materials:
tree plan drawings in print and file format
Assessors must satisfy current standards for RTOs in the assessment of arboriculture units of competency.
Assessment must be conducted only by persons who have:
arboriculture vocational competencies at least to the level being assessed
current arboriculture industry skills directly relevant to the unit of competency being assessed
Foundation Skills
Foundation Skills essential to performance are explicit in the performance criteria of this unit of competency.
