Method quality checklist
- What is the precise scientific or forensic question?
- Is the method validated for the evidence type and intended use?
- What are its controls, limits and sources of error?
- Are the observations and inferences distinguished?
- What alternative explanations should be evaluated?
- Does the report accurately describe the strength and limits of the result?
Check the NIST OSAC Standards Library for relevant current standards. A standard listed there may have a different registry or implementation status; confirm the applicable edition and local laboratory requirements.
