EVIDENCE GUIDE 

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.

Overview of assessment 

A person who demonstrates competency in this unit must be able to provide evidence that they can safely and efficiently recondition band mill wheels within organisational requirements

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

The evidence required to demonstrate competency in this unit must be relevant to, and satisfy, all of the requirements of the elements of this unit and include demonstration of:

• following applicable Commonwealth, State or Territory legislative and regulatory requirements and codes of practice relevant to reconditioning band mill wheels
• following organisational policies and procedures relevant to reconditioning band mill wheels
• reconditioning band mill wheels in line with the work order and within prescribed organisational requirements
• removing and replacing wheels from band mill if faces are to be resurfaced on a metal lathe
• assessing band mill wheel conditions in line with standard operating procedures

Context of and specific resources for assessment 

• Competency is to be assessed in the workplace or realistically simulated workplace
• Assessment is to occur under standard and authorised work practices, safety requirements and environmental constraints
• Assessment of required knowledge, other than confirmatory questions, will usually be conducted in an off-site context
• Assessment is to follow relevant regulatory or Australian Standards requirements
• The following resources should be made available:

• workplace location or simulated workplace
• materials and equipment relevant to undertaking work applicable to this unit
• specifications and work instructions

Method of assessment 

• Assessment must satisfy the endorsed Assessment Guidelines of the FPI11 Training Package
• Assessment methods must confirm consistency and accuracy of performance (over time and in a range of workplace relevant contexts) together with application of required knowledge
• Assessment must be by direct observation of tasks, with questioning on required knowledge and it must also reinforce the integration of employability skills
• Assessment methods must confirm the ability to access and correctly interpret and apply the required knowledge
• Assessment may be applied under project-related conditions (real or simulated) and require evidence of process
