Elements and Performance Criteria

RANGE STATEMENT

The Range Statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance.

Written correspondence, e.g. fax, letters, etc.
Photos of the problem/issue
Video recording the problem/issue


Problems that may be outside of the workers area of responsibility include some of the following:

EVIDENCE GUIDE

The evidence guide provides advice on assessment and must be read in conjunction with the Performance Criteria, Required Skills and Knowledge, the Range Statement and the Assessment Guidelines for this Training Package.

Critical aspects for assessment and evidence required to demonstrate this competency unit:
The individual being assessed must provide evidence of specified essential knowledge as well as skills
Consistency in performance should consider the workers ability to be able to monitor sewage lagoons and effluent systems and check for signs of potential problems
This needs to occur more than once and over a period of time


Access and equity considerations:
All workers in the health industry should be aware of access and equity issues in relation to their own area of work
All workers should develop their ability to work in a culturally diverse environment
In recognition of particular health issues facing Aboriginal and Torres Strait Islander communities, workers should be aware of cultural, historical and current issues impacting on health of Aboriginal and Torres Strait Islander people
Assessors and trainers must take into account relevant access and equity issues, in particular relating to factors impacting on health of Aboriginal and/or Torres Strait Islander clients and communities


Context of and specific resources for assessment:
This unit is best assessed on the job or in a realistic workplace setting
Access to:
a phone and fax when required
tools, materials and equipment for basic repairs and maintenance tasks if necessary
fencing materials if required
simulation of realistic workplace setting for assessment
