40-hour course combines detailed lecture on the scientific bases for friction
ridge identification with intense practical exercises emphasizing correct
comparison techniques. Lecture
topics include the philosophy and
"ACE-V" methodology of
comparing and identifying latent prints. Emphasis is placed on the
relation of ACE-V to the scientific method. Students are equipped to explain the reasons
behind the fundamental principles of permanence and individuality through a
special emphasis on the most thorough and up-to-date information on human
embryological friction ridge formation and friction ridge skin structure.
Training is also given in the recognition of ridge pattern "clues" in
fingerprints and palm prints to help students “orient” the print; identify
which area of skin made a particular latent impression. Related topics include
an introduction to “Daubert”
issues, the recent US v. Plaza ruling, 'tough' identifications and
'close' non-identifications, permanent intentional fingerprint mutilation and non-friction ridge skin
print comparison and identification.

exercises using real inked prints and latent lifts reinforce the lectures.
Students do not automatically work on the same exercises. Each student is
evaluated and assigned personal exercises that are challenging, but achievable.
Individual attention is given during the exercise periods, which comprise almost
half of the course hours. It is an ideal class,
even for senior examiners who desire to increase their speed and accuracy in
doing latent print comparisons.
class was excellent. I felt I learned a lot that I can take
training is also valuable for AFIS technicians who lack traditional latent print
comparison training or experience. Students learn how to evaluate friction ridge
features ignored by AFIS and how to use those features in searching inked prints
and making identifications.
have worked in 'inked prints' for three years with no latent
This is an intermediate
level class. Although every effort will be made to accommodate persons new to
the field, some foundation in latent print matters is strongly recommended prior
to taking the class. Students are expected to be familiar with fingerprint
terminology and should also be doing some latent print comparisons on the job.
Each student must bring their latent print comparison magnifier(s), ridge
counters, and a desk lamp (if necessary) to class with them.
