Tenprint Fingerprint Certification Tenprint Fingerprint Identification Techniques 3 — Questions and Answers
Question 1: During the 'Evaluation' phase of ACE-V, the examiner must reach one of how many possible conclusions?
- Two (match or no match)
- Three (individualization, exclusion, or inconclusive) (Correct answer)
- Four (positive, negative, probable, possible)
- Five (certain, likely, possible, unlikely, excluded)
Correct answer: Three (individualization, exclusion, or inconclusive)
The Evaluation phase of ACE-V requires the examiner to reach one of three conclusions: individualization (identification), exclusion, or inconclusive.
Question 2: Which ridge characteristic describes a single ridge that splits into two ridges?
- Ridge ending
- Bifurcation (Correct answer)
- Enclosure
- Dot
Correct answer: Bifurcation
A bifurcation is the point at which one ridge divides into two separate ridges, forming a fork-like structure.
Question 3: A fingerprint card that is rejected due to smearing or insufficient pressure is typically noted with which designation?
- UP (Unreadable Print)
- ND (Not Determinable) (Correct answer)
- IMP (Improper)
- UT (Unable to Type)
Correct answer: ND (Not Determinable)
ND (Not Determinable) is the standard notation used when the quality of an impression prevents reliable pattern classification.
Question 4: In a plain whorl, how many deltas are present?
- Zero
- One
- Two (Correct answer)
- Three or more
Correct answer: Two
A plain whorl contains exactly two deltas, one on each side of the pattern, which is a defining characteristic of all whorl-type patterns.
Question 5: Which part of the finger typically produces the clearest and most complete ridge impressions on a tenprint card?
- The second joint area
- The fingertip bulb (distal phalanx) (Correct answer)
- The proximal phalanx
- The lateral edge of the finger
Correct answer: The fingertip bulb (distal phalanx)
The bulb of the fingertip (distal phalanx) contains the densest and most individualized ridge detail and is the standard recording area for tenprint impressions.
Question 6: What does the 'V' step in ACE-V stand for, and who performs it?
- Verification, performed by a second independent examiner (Correct answer)
- Validation, performed by a supervisor
- Visualization, performed by the original examiner
- Vetting, performed by legal counsel
Correct answer: Verification, performed by a second independent examiner
Verification is the fourth step of ACE-V, in which a second qualified examiner independently repeats the ACE process to confirm or challenge the original conclusion.
Question 7: Which pattern type is characterized by ridges that enter from one side, recurve, and exit from the same side with one delta?
- Whorl
- Arch
- Loop (Correct answer)
- Tented arch
Correct answer: Loop
A loop has ridges that enter from one side of the finger, curve back, and exit from the same side, with exactly one delta present.
