List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.
Element | Performance criteria |
Elements describe the essential outcomes. | Performance criteria describe the performance needed to demonstrate achievement of the element. |
1. Prepare to apply tree treatments | 1.1 Locate trees on streets using maps 1.2 Recognise trees requiring treatment 1.3 Identify site hazards, assess risks and report to supervisor 1.4 Confirm work zone with work crew and monitor site 1.5 Select and use personal protective equipment 1.6 Select, prepare, and carry out pre-operational and safety checks, on tools and equipment 1.7 Confirm first aid and emergency personnel, equipment and procedures 1.8 Communicate with work team during operations using voice, hand and whistle signals 1.9 Read packaging labels to maintain awareness of work hazards 1.10 Clean or sterilise tools and equipment to avoid disease transfer and biosecurity issues 1.11 Record and implement work health, safety, site, environmental and traffic control measures |
2. Modify environment to maintain health and vigour of tree | 2.1 Remove competing plants to ensure maintenance of adequate space, light, water and nutrient requirements of tree 2.2 Apply nutrient additives at specified rates and locations 2.3 Ameliorate soil structure in relation to aeration and drainage 2.4 Ameliorate soil condition with plant-based mulch application 2.5 Determine benefit and limits of decompaction methods |
3. Apply chemical treatment | 3.1 Calibrate application equipment 3.2 Apply treatment with due regard for environmental implications 3.3 Apply chemicals under supervision |
4. Complete treatment operations | 4.1 Maintain awareness of effect on environment of own work practices 4.2 Clean and store personal protective equipment 4.3 Clear and clean site 4.4 Report applications and treatments and update work records |

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:
spray application equipment
spill kit
measuring and weighing equipment
signage - chemical use
personal protective equipment (PPE)
first aid and emergency kit
traffic management kit
signage - work zone
trees
materials:
tree recognition form
hazard identification and risk control form
equipment and PPE check form
emergency preparation form
work communications form
chemical and treatment application form
tree maintenance form
soil assessment form
work site operations form
work records form
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
