Assessment Checklists

Guidance for ORELAP Assessments

These checklists are used as guidance during ORELAP assessments. The first checklist is general (non-method specific), followed by QA checklists and Method-specific checklists. As additional checklists are developed, they will be added to the website.

Please note: The 'Quality Systems Full Checklist' is a tool for auditors only. It references the 2003 NELAC Standard. While the requirements are similar, the 2009 TNI Standard dropped some requirements, adopted the exact ISO 17025 language, and reorganized the sections. ORELAP is providing this checklist to you as a guideline to the categories we will be auditing; but we will only be writing findings to the 2009 TNI Standard and not the specific wording in the 2003 Quality System Full Checklist. In auditing your own system, labs are encouraged to use the 2009 TNI Quality Systems checklist and develop method specific checklists from Module 4 and Module 5 that relate directly to the instrumentation and method requirements.
