Overview of assessment
Competency must be demonstrated in the ability to perform consistently at the required standard.
Critical aspects for assessment and evidence required to demonstrate competency in this unit
Assessors must be satisfied that the candidate can competently and consistently apply the skills covered in this unit of competency in new and different situations and contexts. Critical aspects of assessment and evidence include:
demonstrating an understanding of the legislative and regulatory framework relevant to air quality
using air quality measurement terminology accurately
interpreting and applying site air sampling/monitoring plans and procedures
collecting reliable, representative air samples in accordance with methods/procedures
operating, maintaining and calibrating air quality measurement instrumentation to produce consistently valid and accurate results
interpreting gross features of data, identifying atypical results as out-of-normal range or an artefact and making relevant conclusions
calculating results using appropriate units/precision
providing accurate, complete records of sampling and testing observations, data and results
working safely and follow relevant legislative requirements for the disposal of waste and the preservation of the environment.
Context of and specific resources for assessment
This unit of competency is to be assessed in the workplace or a simulated workplace environment.
Assessment should emphasise a workplace context and procedures found in the candidate’s workplace.
This unit of competency may be assessed with:
MSL974003A Perform chemical tests and procedures
MSL974009A Undertake field-based remote sensing
MSS025016A Perform sampling and testing of stationary emissions.
The competencies covered by this unit would be demonstrated by an individual working alone or as part of a team.
Resources may include:
vehicles, survey equipment, air sampling/monitoring equipment, cameras, consumables and manuals
work program, enterprise procedures, codes of practice, maps and field protocols.
Method of assessment
The following assessment methods are suggested:
inspection of air samples collected by the candidate
review of air quality measurements, test results, calculations and observations produced by the candidate
review of sampling/testing records completed by the candidate
feedback from peers and supervisors about the candidate’s ability to consistently apply enterprise procedures and work safely
oral and written questioning to check the candidate’s understanding of the principles of air quality sampling/testing, operation of air sampling equipment, test instruments and processing of data
observation of the candidate performing a range of air sampling and testing tasks.
In all cases, practical assessment should be supported by questions to assess underpinning knowledge and those aspects of competency which are difficult to assess directly.
Where applicable, reasonable adjustment must be made to work environments and training situations to accommodate ethnicity, age, gender, demographics and disability.
The language, literacy and numeracy demands of assessment should not be greater than those required to undertake the unit of competency in a work-like environment.
