Accreditation Fundamentals
The accreditation assessment cycle: initial, surveillance, reassessment
A timeline-based view of how assessments work and what evidence is expected at each stage.
Why this matters
Credible accreditation depends on consistent methods, clear decisions, and evidence that stands up to independent review. This publication translates essential expectations into practical steps so teams can prepare, communicate, and operate with confidence.
Key requirements and expectations
- Define the role of accreditation in the conformity assessment ecosystem.
- Clarify who the customer is and what competence means in practice.
- Establish scope boundaries and decision authority.
- Maintain evidence that decisions are impartial and consistent.
- Initial assessment focuses on system readiness and competence.
- Surveillance verifies ongoing control and improvement.
- Reassessment revalidates scope and impartiality over time.
Evidence and records to prepare
- Approved governance or program policies tied to the scope.
- Decision logs that show evaluation and decision separation.
- Conflict of interest declarations for key roles.
- Records that show consistent application over time.
- Assessment plans and reports aligned to each cycle stage.
Common pitfalls to avoid
- Confusing accreditation (CAB competence) with certification (product or org conformity).
- Scope statements that are vague or inconsistent with capability.
- Uncontrolled templates or outdated procedures.
- Decisions made without traceable rationale.
- Treating surveillance as a light audit and missing systemic issues.
Practical checklist
- Define scope boundaries and exclusions in plain language.
- Assign accountable roles and document competence.
- Standardize forms, records, and retention periods.
- Run an internal review before external assessment.
- Maintain a calendar of assessments and evidence refresh points.
