Assessment Conditions
Assessors must satisfy National Vocational Education and Training Regulator (NVR)/Australian Quality Training Framework (AQTF) assessor requirements.
Assessment must occur in workplace operational situations where it is appropriate to do so; where this is not appropriate, assessment must occur in simulated workplace operational situations that reflect workplace conditions.
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.
Resources for assessment must include access to:
tools, equipment, machinery, materials and personal protective equipment currently used in industry
applicable documentation such as legislation, regulations, codes of practice, workplace procedures and operational manuals
range of relevant exercises, case studies and/or simulations.
