1. Which of the following best describes the primary role of a latent print
examiner within a state forensic laboratory system such as Maryland’s
Forensic Sciences Division?
A. To primarily conduct field interrogations of suspects and witnesses and
collect testimonial evidence at crime scenes
B. To perform chemical synthesis of latent print powders and reagents used
by crime scene investigators in the field
C. To analyze, compare, and evaluate friction ridge impressions recovered
from evidence and report findings for investigative and courtroom purposes
D. To supervise all criminal investigations within a jurisdiction, including
homicide, narcotics, and property crime divisions
C
A latent print examiner is responsible for the scientific analysis,
comparison, and evaluation of fingerprint and impression evidence
recovered from items or scenes, producing objective conclusions that may
support investigations and courtroom testimony.
, 2. Which agency is primarily responsible for operating Maryland’s
forensic laboratory system that includes latent print/impression
analysis units?
A. Federal Bureau of Investigation (FBI)
B. Maryland Department of State Police Forensic Sciences Division
C. Maryland Attorney General’s Office
D. U.S. Department of Homeland Security
B
Maryland’s forensic laboratory system, including latent print and
impression analysis services, is operated under the Maryland Department
of State Police Forensic Sciences Division, which provides statewide
scientific support for criminal investigations.
3. Which of the following best describes the accreditation and quality
assurance standards commonly applied to latent print examination
units in Maryland forensic laboratories?
A. Accreditation is optional and laboratories are not required to follow
standardized quality systems
B. Laboratories follow ISO 9000 business standards only, with no forensic-
specific requirements
C. Laboratories comply with ISO 17025 accreditation standards and FBI
Quality Assurance Standards for forensic disciplines
D. Laboratories operate independently without external oversight or
proficiency testing requirements
C
Maryland forensic laboratories follow strict accreditation and quality
systems such as ISO 17025 and FBI Quality Assurance Standards to ensure
reliability, accuracy, and scientific validity of latent print examinations.
4. In forensic latent print examination, what is the most scientifically
accurate definition of a “latent print”?
,A. A deliberately inked fingerprint used for identification cards
B. A visible fingerprint impression created by paint or dye on paper
C. A friction ridge impression unintentionally left on a surface and typically
not visible without development techniques
D. A reconstructed fingerprint pattern created in a laboratory simulation
C
A latent print is an unintentionally deposited friction ridge impression that
is usually invisible or barely visible and must be developed using physical
or chemical methods for examination.
5. Which of the following is the primary scientific basis used in latent
print identification?
A. DNA sequencing of sweat residues found in fingerprints
B. The assumption that fingerprints change significantly over time due to
aging
C. The comparison of ridge detail patterns and their uniqueness and
persistence across individuals
D. The statistical probability that two people may share identical fingerprints
in a population sample
C
Latent print identification is based on the principle that friction ridge
patterns are unique to individuals and remain persistent over time,
allowing examiners to compare ridge detail for identification.
6. Which method is most commonly used to visualize latent prints on
non-porous surfaces such as glass or metal?
A. Ninhydrin treatment
B. Cyanoacrylate (superglue) fuming
C. DNA amplification
D. Radiographic imaging
, B
Cyanoacrylate fuming is widely used for non-porous surfaces because it
reacts with fingerprint residues to form a white polymer that makes latent
prints visible for further enhancement and comparison.
7. What is the correct sequence of the ACE-V methodology used in latent
print examination?
A. Analyze, Compare, Evaluate, Verify
B. Acquire, Confirm, Examine, Validate
C. Analyze, Classify, Examine, Verify
D. Assess, Compare, Examine, Validate
A
ACE-V stands for Analyze, Compare, Evaluate, and Verify, which is the
standardized methodology used to ensure systematic and repeatable
latent print examinations.
8. Which of the following best describes the purpose of proficiency
testing in forensic latent print examination?
A. To train new police officers in fingerprint collection procedures
B. To evaluate an examiner’s competence by periodically testing their
analytical performance using known standards
C. To replace formal education requirements for forensic scientists
D. To eliminate the need for laboratory accreditation programs
B
Proficiency testing is used to assess and document an examiner’s ongoing
competence by having them analyze controlled test samples and
demonstrate accurate forensic performance.
9. Which of the following is typically required for qualification as a latent
print examiner in Maryland forensic laboratories?
