The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required knowledge and skills, the range statement and the assessment guidelines for this Training Package.

Critical aspects for assessment and evidence required to demonstrate competency in this unit

The evidence required to demonstrate competence in this unit must be relevant to and satisfy all of the requirements of the Elements, Performance Criteria, Required Skills, Required Knowledge and include demonstration of applying:

required knowledge and skills

relevant legislation and workplace procedures

other relevant aspects of the range statement.

Assessment must include exercises that demonstrate competent performance of the following in a range of situations:

planning a derailment investigation

evidence preservation and collection

producing a derailment investigation report.

Context of and specific resources for assessment

Performance is demonstrated consistently over time and in a suitable range of contexts.

Resources for assessment include access to:

a range of relevant exercises, case studies and/or other simulated practical and knowledge assessment, and/or

an appropriate range of relevant operational situations in the workplace.

In both real and simulated environments, access is required to:

relevant and appropriate materials and equipment, and

applicable documentation including workplace procedures, regulations, codes of practice and operation manuals..

Method of assessment

As a minimum, assessment of knowledge must be conducted through appropriate written/oral tests.
