  • The competencies covered by this unit would be demonstrated by an individual working alone or as part of a team.
  • Where applicable, reasonable adjustment must be made to work environments and training situations to accommodate ethnicity, age, gender, demographics and disability.
  • Assessment methods must be by direct observation of tasks and include questioning on underpinning knowledge to ensure its correct interpretation and application.
  • Assessment may be applied under project related conditions (real or simulated) and require evidence of process.
