CASS Assessors
Registration Scheme for Functional Safety Assessors
The CASS Registered Functional Safety Assessor scheme is a registration scheme for experienced functional safety assessors who use the CASS methodology. A candidate for the scheme requires a referee and proposer to vouch for their competence. Registration is based on a peer review of the assessors’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 competence in their particular scope which is evaluated by a panel of other qualified practitioners.
- CASS 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 CASS is unchanged (i.e. without the ‘CASS Mark’).
The CASS Register Functional Safety Assessor scheme uses a model to consider five layers of an applicants knowledge and experience. The scheme manual defines requirements for the application and evaluation process. The applicant will require a proposer and a referee. The five layers are:
- Layer-1: Basic academic and professional qualifications
- Layer-2: Structured / formal Functional Safety (FS) training and self-learning
- Layer-3: FS practitioner experience (specificed scope)
- Layer-4: FS assessor experience (specified scope)
- Layer-5: Knowledge of CASS methodology
