This 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. Students are equipped to explain the reasons behind the fundamental principles of permanence and individuality through a special emphasis on human embryological friction ridge development and friction ridge skin structure. Training is also given in the recognition of ridge pattern “clues” to help students identify which finger or which area of skin made a particular latent impression. Related topics include an introduction to "Daubert" issues, the recent US v. Plaza ruling, permanent intentional fingerprint mutilation and non-friction ridge skin comparison and identification. This is an excellent course to help the student prepare for the IAI certification exam. Comparison 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 exercise periods. It is an ideal class, even for senior examiners who desire to increase their speed and accuracy in doing latent print comparisons.
This 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.
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 a latent print comparison magnifier(s) and ridge counters.
