Assessment Conditions
Assessors must:
satisfy the assessor competency requirements that are in place at the time of the assessment, as set by the VET regulator
have vocational competency in determining tanning requirements for hide, skin and leather, at least to the level being assessed, with relevant industry knowledge and experience.
Assessment should occur in operational workplace situations. Where this is not possible, or where personal safety or environmental damage are limiting factors, assessment must occur in a sufficiently rigorous simulated environment reflecting realistic operational workplace conditions. This must cover all aspects of workplace performance, including environment, task skills, task management skills, contingency management skills and job role environment skills.
Assessment processes and techniques must be appropriate to the language, literacy and numeracy requirements of the work being performed and the needs of the candidate.
Conditions for assessment must include access to all tools, equipment, materials and documentation required, including relevant workplace procedures, product and manufacturing specifications associated with this unit.
