Forms
The following forms are provided for reference and use.
| Form | Purpose |
|---|---|
| Laboratory Certification Program Evaluation Form | A form used to evaluate various performance areas within the NC WW/GW LC program including auditor performance, inspection reports and program performance. [Extended Format] |
| Laboratory Certification Program Short Survey | A short survey to provide feedback on the services provided by the NC WW/GW Laboratory Certification program. [Short Format] |
| Notice of Finding for Immediate Response (NOFIR) Form | A form used by NC WW/GW LC auditors during on-site inspections when a Finding is judged to be severe to the extent that immediate correction or suspension of the action is required. |
| Sample Non-conformance Notification | Example of a form that can be used when laboratories submit notification to the NC WW/GW LC program of samples analyzed that do not meet sample collection, preservation or holding time requirements. |
