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:

act on a request to inspect a tree

perform site, equipment and administration preparations and checks

inspect trees for general condition, structural defects, damage and disease

conduct a site and tree hazard identification and risk control assessment

document the hazards identified and the risk controls selected

record findings and inform client.

Context of and specific resources for assessment

The candidate is to be assessed against the relevant types of systems and processes applicable in the Arboriculture sector. 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.

The range statement relates to the unit of competency as a whole.

Species may include:

tree species and tree like vegetation forms.

Inspections may include:

tree inspections are included as a standard form for recording and reports undertaken within the fields of arboriculture and horticulture and are conducted in all areas of urban and regional settings such as residential areas and public open spaces.

Reports may include:

botanical and common names, age, health, types of defects, problems and conditions are required information for each specific tree in an inspection report.
