Evidence Required

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 perform yarder operations to recover felled logs 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 yarder operations

following organisational policies and procedures relevant to yarder operations

conducting yarder operations to recover felled logs in line with the work order and within prescribed organisational tolerances

setting up a yarder in line with site conditions

assisting in shifting lines in line with the hook tenders instructions

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 offsite 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 FPI Training Package

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 projectrelated conditions real or simulated and require evidence of process

Assessment must confirm a reasonable inference that competency is able not only to be satisfied under the particular circumstance but is able to be transferred to other circumstances

Assessment may be in conjunction with assessment of other units of competency

The assessment environment should not disadvantage the candidate

Assessment practices should take into account any relevant language or cultural issues related to Aboriginality gender or language backgrounds other than English

Where the participant has a disability reasonable adjustment may be applied during assessment

Language and literacy demands of the assessment task should not be higher than those of the work role
