Inter-Examiner Agreement
Definition
The degree to which independent examiners reach the same conclusion when shown the same evidence. Low inter-examiner agreement is a signal that a method's conclusions are not reproducible and therefore not reliable as a scientific basis for testimony.

- Odontology and pattern evidence quality
- Measures
- Whether independent examiners reach the same conclusion

- Relevance
- Bears on admissibility and scientific reliability
Common questions
Why does low inter-examiner agreement undermine courtroom testimony?+
If qualified examiners looking at identical evidence reach different conclusions, the method cannot be shown to produce a consistent, verifiable result, which weakens claims that the conclusion reflects an objective finding rather than individual judgment.
How is inter-examiner agreement usually measured in validation studies?+
Researchers give the same set of cases to multiple examiners working independently and compare their conclusions, often reporting the proportion of matching calls or a statistical agreement measure such as a kappa coefficient.
