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.

Field
Odontology and pattern evidence quality
Measures
Whether independent examiners reach the same conclusion
Low value implies
Poor reproducibility of the method
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.
