A Crownship Assessor supported by an Internal Verifier will provide the candidate(s) with advice, guidance and formal assessment. 

The aim of the induction is to ensure the candidate(s) are clear about the process and to establish achievable time scales, also to clarify which qualification pathway is relevant to the work they are involved with. This can be completed via telephone, skype and email and or face to face.

When sufficient evidence for each unit has been obtained, this will be formally assessed and verified when all units are complete, full certification will be applied for.
