Assessment Conditions
Assessment texts and tasks reflect those typically found in the workplace.
Individuals can access a range of established support resources.
Culturally appropriate processes and techniques suited to the language, literacy and numeracy capacity of individuals and the work being performed must be used.
Reasonable adjustments can be made to ensure equity in assessment for people with disabilities.
Assessors must satisfy NVR/AQTF assessor requirements, have a sound knowledge of the ACSF and have demonstrable expertise in the vocational contextualisation and assessment of the core skill - numeracy.
