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 prepare and advise on a broad range of timber roof truss details using computers |
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 preparing and advising on a broad range of timber roof truss details using computers following organisational policies and procedures relevant to preparing and advising on a broad range of timber roof truss details using computers preparation and advice on a broad range of timber roof truss details using computers preparation of roof truss layouts and production documentation for each roof truss type identified in the range statement preparation of roof truss layouts and production documentation where interaction between roof truss types is required |
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 comply with 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 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 |
