ISO 17025 Checklist for Document Review and Audit Preparation
Free ISO 17025 checklist for document review, accreditation readiness and audit preparation.
This ISO 17025 checklist is designed to support document review activities by identifying key points that should be verified within a laboratory's quality documentation.
It is not an audit or accreditation assessment, but a practical tool for evaluating how ISO 17025 requirements are addressed within existing documents.
Organization and Responsibilities
- Are responsibilities and authorities defined and documented?
- Are key quality-related roles identified?
- Are impartiality and independence requirements addressed?
Document Control
- Are quality documents identified, dated and version controlled?
- Are applicable documents available to relevant personnel?
- Are obsolete documents adequately controlled?
Personnel Competence
- Are competence requirements defined for each activity?
- Are training and authorizations documented?
- Is competence periodically evaluated?
Methods and Validation
- Are testing or calibration methods documented?
- Are methods suitable for their intended use?
- Are validation or verification activities documented?
Equipment and Traceability
- Are equipment items identified and monitored?
- Is metrological traceability documented?
- Are maintenance and verification activities recorded?
Records and Evidence
- Are required records clearly defined?
- Is evidence retained under controlled conditions?
- Can links between requirements and evidence be identified?
Document Review and Audit Preparation
- Is ISO 17025 document review performed regularly?
- Are identified gaps analyzed?
- Are follow-up and clarification actions recorded?

This checklist can be used alongside an ISO 17025 document review process and during preparation for accreditation assessments and audits.
Why Use an ISO 17025 Checklist?
An ISO 17025 checklist helps laboratories verify whether the requirements of ISO/IEC 17025 are adequately addressed within their quality documentation. It provides a structured approach for reviewing procedures, quality manuals, work instructions and supporting records before internal audits, management reviews and accreditation assessments.
Many nonconformities identified during accreditation audits are not caused by technical failures but by incomplete, inconsistent or outdated documentation. A systematic checklist helps laboratories identify missing requirements, clarify responsibilities, improve traceability and ensure that documented processes accurately reflect laboratory practices.
Using a checklist also promotes consistency between reviewers. Whether the review is performed by a quality manager, technical manager or consultant, a structured review process reduces the risk of overlooking important ISO 17025 requirements.
How to Perform an ISO 17025 Document Review
An effective ISO 17025 document review begins by defining the review scope and identifying the documents involved. These may include quality manuals, procedures, work instructions, training records, equipment records, calibration certificates, validation reports and internal audit reports.
Each document should be evaluated against applicable ISO 17025 requirements to determine whether requirements are fully addressed, partially addressed or missing. Particular attention should be paid to document control, competence management, equipment management, method validation, metrological traceability and risk management activities.
Reviewers should verify that responsibilities are clearly assigned, records are retained appropriately and evidence exists to demonstrate implementation of documented processes. The outcome of the review should be recorded together with identified gaps and improvement opportunities.
Common ISO 17025 Documentation Findings
Several recurring issues are frequently identified during ISO 17025 document reviews. One common finding is incomplete definition of responsibilities and authorities. Laboratories sometimes describe activities without clearly identifying who is authorized to perform, review or approve them.
Document control weaknesses are also common. Procedures may exist but lack revision history, approval records or controls preventing the use of obsolete versions. Training and competence records may be incomplete, making it difficult to demonstrate personnel qualification for specific activities.
Another frequent finding concerns metrological traceability. Laboratories may maintain calibration records but fail to clearly demonstrate traceability to appropriate reference standards. Similar gaps are often identified in equipment management, method validation and corrective action documentation.
Preparing for an ISO 17025 Accreditation Audit
A comprehensive document review is one of the most effective ways to prepare for an ISO 17025 accreditation assessment. Before an audit, laboratories should ensure that quality documentation is current, approved and readily accessible to personnel.
Supporting evidence should also be available, including training records, equipment records, management review outputs, internal audit reports, corrective actions and method validation records. Assessors evaluate both documented processes and evidence demonstrating their effective implementation.
Using an ISO 17025 checklist during audit preparation helps laboratories verify requirement coverage, identify weaknesses before assessment and reduce the likelihood of audit findings. It also improves review efficiency by ensuring that required information can be located quickly during the assessment process.
Frequently Asked Questions
What is an ISO 17025 checklist?
An ISO 17025 checklist is a structured tool used to verify whether laboratory documentation addresses the requirements of ISO/IEC 17025. It helps laboratories prepare for audits, accreditation assessments and internal reviews.
Can an ISO 17025 checklist replace an audit?
No. A checklist supports document review and audit preparation but does not replace an internal audit, accreditation assessment or certification activity.
Which documents should be reviewed?
Typical documents include quality manuals, procedures, work instructions, training records, validation reports, calibration records, equipment files and corrective action records.
