Bullet Black Box Participant Background Survey
17 April 2019
Note the actual survey will be available online using Google forms
The purpose of this study is to evaluate the accuracy, repeatability, and reproducibility of bullet comparisons by
firearms examiners. The study is being conducted by Noblis and NIST.
Participation will be open to US firearms examiners who have conducted operational casework in the past year. Participants are required to complete this on-line background questionnaire.
Questions regarding the study should be directed to firearms@noblis.org .

Yes
No

If the firearm is not available when conducting a comparison of bullets, does your agency allow making elimination (exclusion) conclusions when all class characteristics agree?
