The first professional certification program for forensic scientists was established in 1977, the IAI's Certified Latent Print Examiner program, which issued certificates to those meeting stringent criteria and had the power to revoke certification where an individual's performance warranted it.

In terms of fingerprint identification, FBI agents who are responsible for examining the prints to determine the points of similarity in order to tell if they have secured a match, varies from examiner to examiner and from laboratory to laboratory. The decision process, unfortunately, is entirely subjective to the individual running the tests ...
To match a print, a fingerprint technician scans in the print in question, and computer algorithms are utilized to mark all minutia points, cores, and deltas detected on the print. In some systems, the technician is allowed to perform a review of the points that the software has detected, and submits the feature set to a one-to-many (1:N) search.
It states that two latent print examiners then identified the handprint as that of Darling, who has a lengthy prior record, according to court records. Defendant remains in prison following ...
Fingerprint powder is useful for the detection and collection of latent fingerprints, but that is not all the analysis that can be done. Kaplan-Sandquist, LeBeau, and Miller conducted a study where they tested fingerprint development methods with the MALDI/TOF MS. The fingerprint powder was found to be useful as a MALDI matrix. [11]
Examiners performing a restoration first sand the area where the serial number used to be. This removes any debris from the area left when the serial number was obliterated. [28] The examiner then chooses a chemical, usually an acid, [28] that will be used to slowly bring the number back to the surface. The type of chemical that is used depends ...
Similarly to the use of fingerprint powder in fingerprint analysis, fingerprint powder is used when there is a latent footprint that is composed of mostly oils, instead of dust or dirt. The use of fingerprint powder allows the analyst to more easily find the print and identify the characteristics of the print. [2]
an examiner should follow appropriate case examination protocols carefully and evaluate all possible propositions, an examiner should be properly trained and their training should include adequate testing of their abilities, the formal case examination procedure should incorporate some form of secondary review (ideally, independent in nature) and
