CASS Assessors

The CASS Registered Functional Safety Assessor (RFSA) scheme is a registration scheme for experienced functional safety assessors who use the CASS methodology. The RFSA scheme is open to all active members of The 61508 Association (T6A) and all active members of The CASS Scheme Association (TCSA). A candidate for the scheme must be well known within the association and requires a referee and proposer to vouch for their technical capability and experience. Registration is based on a peer / panel review of the assessor’s knowledge and experience in their claimed scope and is not a personnel competence certification scheme.

How the CASS Registered Functional Safety Assessor scheme works:

• Candidates provide evidence of their assessor training / experience in their particular scope which is evaluated by a panel of other qualified practitioners.
• The CASS Scheme Association maintains and publishes a register of functional safety assessors (RFSAs) who have met the registration requirements.
• RFSAs are permitted to use the ‘CASS Mark’ (which includes their personal ID) on their assessment reports.
• The CASS Scheme Association does not view or accept responsibility for any assessment report.
• Registration is optional – the existing use of the CASS methodology is unchanged (i.e. without the ‘CASS Mark’).
