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 including the use of risk control measures as specified in the performance criteria
    • demonstrate the ability to produce urban road project drawings in accordance with the requirements of AS1100.401 and job specifications on more than one occasion and in different

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 instructions.
    • access to workplace or work real environment and a variety of conditions
    • operational access to manual or computed aided drafting equipment and consumables
    • access to relevant Australian Standards, 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 colleagues, supervisors, clients or other appropriate
  • Questioning techniques should not require language, literacy and numeracy skills beyond those required in this unit of competency.
