Other units of competency that could be assessed with this unit
This unit could be assessed on its own or in combination with other units relevant to the job function, for example all the units covering landfill maintenance at a similar level may be able to be assessed in conjunction.
Where assessment covering a cluster of units is to be conducted, it may be useful to assess the units together as far as practicable. This may be most useful when an experienced applicant is being assessed for the purpose of recognition of current competency.

Resources required to assess this unit

The following resources should be available:

company environmental management strategy
plant and equipment for rehabilitation
safety barriers and signage
materials for rehabilitation
PPE
OHS requirements
environmental protection legislative requirements
site safety plan.

Gaining evidence to assess this unit
For valid and reliable assessment of this unit, the competency should be demonstrated over a period of time and be observed by the assessor (or assessment team working together to conduct the assessment). The competency is to be demonstrated in a range of situations, which may include customer/workplace interruptions and involvement in related activities normally experienced in the workplace.
Evidence of competency is best obtained by observing activities in the field and reviewing the rehabilitation of a landfill site under normal industry operating conditions. If this is not practicable, observations in realistic simulated environments may be substituted.

Consistency in performance
Assessment requires that strategies meet the objectives of clients and comply with industry expectations in the particular client environment. If the environment is narrowly defined or is not representative of industry needs, it will be necessary to assess the unit within a variety of waste management environments or different client needs to assess competency in the rehabilitation of a landfill site.
Oral questioning or written assessment and hypothetical situations (scenarios) may be used to assess underpinning knowledge. (In assessment situations where the candidate is offered a preference between oral questioning and written assessment, questions are to be identical.)
Supplementary evidence may be obtained from relevant authenticated correspondence from existing supervisors, team leaders or specialist training staff.
Note: All practical demonstrations must adhere to the safety and environmental regulations relevant to each state or territory.
