All candidates must have a mentor to support them through the accreditation process and to give them the best chance of passing the assessment process.

Candidates should have a minimum of three meetings with their mentor preparing for their accreditation and for the role of a screener. This should include observing scoping. The mentor is not necessarily a trainer or assessor but can share their experiences and help in the preparation process. The mentor would usually, but not necessarily, be based at the same screening centre as the applicant.
