Elements and Performance Criteria

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.
Key generic identifiersmay include:
date
location
time
pH, etc
Standard computer programs/software may include:
database software such as MS Access
spreadsheet software such as MS Excel
corporate software
Addressing water quality issuesmay include:
re-testing water
organising with lab to re-test
following relevant organisational procedure for dealing with failed water quality results
informing regulatory authority e.g. Health Dept.

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.
Critical aspects for assessment and evidence required to demonstrate competency in this unit
The candidate should demonstrate the ability to use water quality management knowledge to:
apply the principles of water quality science to monitoring program design
apply the principles of water science to water quality data analysis and interpretation
design and operate a water quality data base
take action if there are water quality issues
Context of and specific resources for assessment
















Access to the workplace and resources including:
documentation that should normally be available in a water industry organisation
workplace specific equipment and technology
supervision and experienced team members to provide observations, feedback and third party reports
enterprise operating procedures and work allocation
relevant codes, standards, and government regulations
Where applicable, physical resources should include equipment modified for people with disabilities.
Assessment processes and techniques must be culturally appropriate and appropriate to the language and literacy capacity of the candidate and the work being performed.
Validity and sufficiency of evidence require that:
competency will need to be demonstrated over a period of time reflecting the scope of the role and the practical requirements of the workplace
where the assessment is part of a structured learning experience the evidence collected must relate to a number of performances assessed at different points in time and separated by further learning and practice
a decision of competence should only be made when the assessor has complete confidence in the person’s competence over time and in various contexts
all assessment that is part of a structured learning experience must include a combination of direct, indirect and supplementary evidence
where assessment is for the purpose of recognition (RCC/RPL), the evidence provided will need to be authenticated and show that it represents competency demonstrated over a period of time
assessment can be through simulated project-based activity and must include evidence relating to each of the elements in this unit
In all cases where practical assessment is used it will be combined with targeted questioning to assess the underpinning knowledge. Questioning will be undertaken in a manner appropriate to the skill levels of the operator, any cultural issues that may affect responses to the questions, and reflecting the requirements of the competency and the work being performed.
Method of assessment
The following methods are suggested:
assessment in the workplace or in a simulated workplace and under the normal range of workplace conditions
techniques for gathering evidence of competency may include a combination of:
observation of performance
written and/or oral questioning to assess knowledge and understanding
exams
completion of workplace documents and reports produced as part of routine work activities
third party reports from experienced practitioners, supervisors and specialists
