ISO 17025 Gap Assessment Checklist

An ISO 17025 gap assessment checklist is used to find the gap between where a testing or calibration laboratory is and what ISO/IEC 17025:2017 requires, usually before a first accreditation or a reassessment. Its purpose is a clear picture of conformity: which requirements are met, which are partly met, and which are gaps, with the evidence and an action plan to close them. It is a readiness and planning tool, distinct from an internal audit of an operating system.

Working through the assessment setup, the conformity status of each requirement, the evidence and gaps by clause, prioritisation and risk, the action plan and owners, and accreditation readiness, the checklist turns the standard into a plan. Because the evidence and the size of each gap depend on the laboratory's scope and maturity, the checklist records the status and actions rather than assuming any laboratory starts from the same point.

Laboratories heading for ISO/IEC 17025 accreditation often work from a to-do list rather than a structured gap assessment. Requirements get marked done without evidence, the hardest technical gaps in traceability, uncertainty and validation are underestimated, and there is no view of which gaps actually block accreditation. The laboratory requests assessment before it is ready and picks up avoidable nonconformities.

An ISO 17025 gap assessment checklist fixes that by recording, for every requirement, a conformity status, the evidence or the gap, and a prioritised action with an owner. Management can see the true readiness position, focus effort on the gaps that block accreditation, and only request assessment when the plan is genuinely complete.
