EVIDENCE GUIDE

The evidence guide provides advice on assessment and must be read in conjunction with the Elements, Performance Criteria, Required Skills and Knowledge, the Range Statement and the Assessment section in Section B of the Accreditation Submission.

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

  • Assessors must be satisfied that the candidate can competently and consistently perform all elements of the unit as specified by the associated performance criteria, including required skills and knowledge. Specifically they must be able to:
    • implement OHS/WHS procedures and practices as specified in the performance criteria
    • demonstrate the ability to produce detailed structural steel drawings in accordance with AS 1100.501 and AS4100 and AISC Handbook on more than one occasion and in different contexts.

Context of and specific resources for assessment

  • This unit may be assessed on the job, off the job or a combination of both on and off the job. Where assessment occurs off the job, that is the candidate is not in productive work, then an appropriate simulation must be used where the range of conditions reflects realistic workplace situations. The competencies covered by this unit would be demonstrated by an individual working alone or as part of a team. The assessment environment should not disadvantage the candidate
  • Resources required for assessment include:
    • OHS/WHS policy and work procedures and
    • access to workplace or work real environment and a variety of conditions
    • operational access to manual or computer aided drafting equipment, references and consumables
    • access to relevant Australian Standards, AISC handbook, plans, drawings and instructions and manufacturer’s specifications/manuals

 

Methods of assessment

For valid and reliable assessment of this unit, evidence should be gathered through a range of methods to indicate consistent performance.

  • Evidence must involve demonstration of practical skills and may also include:
    • observation of processes and procedures
    • oral and/or written questioning on required knowledge and skills
    • testimony from supervisors, colleagues, clients and/or other appropriate persons
    • inspection of the final product or outcome
    • a portfolio of documented
  • Where performance is not directly observed any evidence should be authenticated by appropriate
  • Questioning techniques should not require language, literacy and numeracy skills beyond those required in this unit of competency.
