Certification Process
1
Application & Review
Submit your application. CAS reviews your organisation's scope, personnel, sites, and activities to prepare a detailed audit time calculation and formal commercial proposal.
2
Stage 1 — Document Review
On-site or remote review of your management system documentation, readiness assessment, and confirmation of Stage 2 audit scope and plan.
3
Stage 2 — On-site Audit
Full on-site audit of the implemented management system against the standard's requirements. Findings are reported; nonconformities must be closed before certification.
4
Certification Decision
CAS's independent certification committee reviews the audit findings and issues the certificate. The certificate is valid for 3 years.

Frequently Asked Questions
No. ISO/IEC 17025 is the general standard for laboratory competence. ISO 11133 specifically addresses culture media preparation and testing for microbiological laboratories — it is complementary to ISO 17025.
