Revised Draft for Comment Revised Draft for Comment Standards for Examining Friction Ridge Impressions and Resulting Conclusions

Friction ridge impression examinations are conducted by examiners using the Analysis, Comparison, Evaluation, and Verification (ACE-V) methodology, which includes both qualitative and quantitative aspects. ACE is not generally applied as a strictly linear process because it may include a return to any previous phase. Application of ACE includes observations, measurements, assessments, decisionmaking and documentation that is enabled by the training, skill and experience of the examiner.
