ACE-V Standards and Controls
1. The use of magnification to view the details and the use of selected appropriate lighting to illuminate the details.
2. Latent Print Examiners must be successfully trained to competency before effecting an identification. For example, see SWGFAST guidelines.
3. Correspondence in friction ridge formations is based upon their agreement in a.) shape, b.) orientation c.) location and d.) spatial (group) relationship.
4. The Principles of the Methodology are as follows:
a.) Find agreement of corresponding detail in such a number and significance.
b.) Preclude the possibility of the chance occurrence of that relationship of corresponding detail in another fingerprint.
c.) With no significant, unexplained differences to account for.
5. No minimum, fixed number of corresponding detail must be present to effect identifications. This criteria has been established by I.A.I. Resolution #7, the Ne'urim Declaration, and by SWGFAST's "Quality Assurance Guidelines for Latent Print Examiners".
6. The Conclusion is limited to the following findings which are commensurate with this methodology:
a.) Identification (Individualization).
b.) Non-Identification (Exclusion).
c.) Inconclusive.
7. An Identification is the determination by a competent examiner that two friction ridge impressions originated from the same source.
8. A Non-Identification is the determination by a competent examiner that two friction ridge impressions originated from two different sources.
9. An Inconclusive determination is the result of a competent examiner being unable to identify or exclude the source of a friction ridge impression.
10. Qualified Conclusions (possible, probable or likely Identifications) are outside the acceptable limits of the Science of Friction Ridge Identification. Friction ridge identifications are absolute conclusions.
11. All identifications must be verified by a qualified Latent Print Examiner, per SWGFAST guidelines.
12. Principle of Uniqueness: "All persons, even identical twins, have different fingerprints".
13. Principle of Permanence: "A person's friction skin structures do not change during that person's lifetime, other than to grow larger, or possibly be affected by injury or skin disease".
