Tenprint Fingerprint Certification Tenprint Fingerprint Classification Systems 2 — Questions and Answers
Question 1: What is the 'final' in the Henry Classification System?
- The last entry in the AFIS database
- The ridge count of the right little finger loop (Correct answer)
- The date the classification was finalized
- The examiner's approval signature
Correct answer: The ridge count of the right little finger loop
The final is the ridge count of the right little finger if it is a loop pattern, used to further differentiate similar classifications.
Question 2: Which pattern type is assigned a value in calculating the Henry primary classification?
- Arch
- Loop
- Whorl (Correct answer)
- Tented Arch
Correct answer: Whorl
Only whorls contribute numerical values in the primary classification formula; arches and loops count as zero.
Question 3: In the NCIC fingerprint classification system, how are patterns encoded?
- Using Roman numerals
- Using a two-letter code per finger
- Using a single uppercase letter per finger (Correct answer)
- Using a numeric ridge count only
Correct answer: Using a single uppercase letter per finger
The NCIC system uses a single uppercase letter to represent the pattern type for each of the ten fingers in sequence.
Question 4: What does 'ridge tracing' determine in whorl classification?
- The number of ridges between two deltas
- Whether a whorl is inner, meeting, or outer based on tracing from the left delta (Correct answer)
- The direction of ridge flow in the pattern area
- The ink coverage on the fingerprint card
Correct answer: Whether a whorl is inner, meeting, or outer based on tracing from the left delta
Ridge tracing follows the ridge from the left delta and classifies the whorl as inner (I), meeting (M), or outer (O) relative to the right delta.
Question 5: What is the 'major division' in the Henry classification system based on?
- The age and sex of the subject
- The pattern types on the thumbs (Correct answer)
- The total ridge count across all fingers
- The number of scars present
Correct answer: The pattern types on the thumbs
The major division uses the pattern types found on the thumbs and further subdivides the classification based on ridge count or tracing.
Question 6: Which classification element uses the pattern type of the middle fingers (positions 3 and 8)?
- Primary classification
- Secondary classification
- Subsecondary classification (Correct answer)
- Special loop classification
Correct answer: Subsecondary classification
The subsecondary classification evaluates index, middle, and ring fingers, including middle finger patterns in positions 3 and 8.
