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.
An individual demonstrating competency must satisfy all of the elements and performance criteria in this unit.
There must be evidence that the individual has analysed and critiqued a minimum of five different diagnostic test results.
For each of the five tests, there must also be evidence that the individual has:
compiled a portfolio of sample reports of diagnostic test results, including the following types of tests:
dynamic and static loading
drill resistance measurement device
sap flow measurements
electronic impedance
chlorophyll fluorescence
increment core
sonic tomography
radar imaging system
bulk density
soil and pH tests
compiled peer reviewed papers on the use of each diagnostic tool
reviewed diagnostic tool specifications and user manuals and researched output ranges for each diagnostic tool
identified key thresholds and benchmarks
determined suitability of tool selection for purpose of test
identified and evaluated testing methods
assessed relevance, benefits and limitations and determined assumptions of methodology
determined veracity of the equipment, software and systems
accessed available raw data and testing evidence and verified data relevance and accuracy
reviewed references cited in the report and identified inconsistencies
evaluated test results and completed the following:
recorded discrepancies against standards
assessed the suitability of diagnostic tool for purpose
highlighted unsupported statements and factual errors
detailed significant omissions, errors and ambiguities
detailed inconsistencies and errors of logic
identified variances to specifications
assessed the suitability of the testing process as fit for purpose
analysed test results, compared test outcomes with original interpretation and considered and accounted for anomalies
determined validity of outcomes of original report
developed substantiated positions for critical analysis
determined further testing required to verify results
compiled the analysis and reviewed completeness and accuracy of analysis
recorded analysis outcomes and rationale and documented the analytical processes
provided alternate analysis and conclusion and documented critique in a report
presented report according to agreed format and within agreed timelines.
An individual must be able to demonstrate the knowledge required to perform the tasks outlined in the elements and performance criteria of this unit. This includes knowledge of:
diagnostic tests and tools used in arboriculture and their purpose, including:
dynamic and static loading
drill resistance measurement device
sap flow measurements
electronic impedance
chlorophyll fluorescence
increment core
sonic tomography
radar imaging system
bulk density
soil and pH tests
specifications of arboricultural diagnostic tools, including:
arboriculture terminology and language used in tree diagnostics
data output, interpretation and output ranges, key thresholds and benchmarks
diagnostic tool selection and testing methods
developing an evidence-based critique of testing procedures and results, including:
reviewing and verifying cited references and data reports
data accuracy and relevance
testing diagnostic tools and methods against standards and quality assurance
identifying non-conformances in documentation of results and reports, including:
unsupported statements and factual errors
significant omissions, errors and ambiguities
variances to specifications and standard procedures
incorrect use of arboricultural terminology
verification and falsification of results
selecting and determining the suitability of diagnostics tools and testing procedures and deciding best fit for purpose
analysing test results and use of industry benchmarks and standards.
Assessment of the skills in this unit of competency must take place under the following conditions:
physical conditions:
an arboriculture work site or environment that accurately represents workplace conditions
resources, equipment and materials:
computer with word processing software and statistical analysis software
specifications:
test equipment manuals, standard procedures and quality standards
sample reports for the diagnostic test methods listed in the performance criteria.
Assessors of this unit must satisfy the requirements for assessors in applicable vocational education and training legislation, frameworks and/or standards. In particular, assessors must have:
arboriculture vocational competencies at least to the level being assessed
current arboriculture industry skills directly relevant to the unit of competency being assessed.
