Elements and Performance Criteria

Performance Evidence

An individual demonstrating competency must satisfy all of the elements and performance criteria in this unit.

There must be evidence that the individual has contextualised diagnostic test results for each of the following five primary domains for trees:

edaphic environment.

There must also be evidence that the individual has:

conducted a literature review of peer-reviewed research and relevant case studies

operated diagnostic testing equipment

interpreted underpinning scientific principles of test processes

determined the diagnostic assumptions and limitations of the testing process for the selected diagnostic tool

analysed quantification, variance and tolerance requirements

investigated and verified calibration baselines for diagnostic equipment

verified calibration processes have been performed on test equipment

selected testing processes for each of five primary tree domains

selected diagnostic tools and contextualised the testing process for each domain

defined research method to be used

conduct a literature review for current research and science of each primary domain

established efficacy of the test for each primary domain

conducted a diagnostic test project

analysed test results for performance metrics of selected diagnostic tools

interpreted results against benchmark and anticipated ranges

confirmed predictive responses in terms of post-treatment to pre-treatment results

articulated meaning of results within context of primary domain

provided an informed prognosis

researched management options and lag time
