Updated the Detail Archives
_________________________________________

Last week

We looked at the recently approved SWGFAST Draft for Comment entitled Standard for the Documentation of ACE-V. It is now available as a .pdf on the SWGFAST website: (http://www.swgfast.org)

 

This week

We look a the other approved Draft for Comment. It combines 2 previous SWGFAST recommendation documents, frames them as a standard, and applies to both the tenprint and the latent print disciplines.  Readers are encouraged to obtain the .pdf versions directly from the site instead of relying on representations in the Detail or e-mail forwards because of potential formatting differences. As with last week, the SWGFAST Chairperson requests that all feedback on this draft standard be provided to the Executive Secretary by September 4, 2009 at: MAB@fss.ocgov.com.

Three other "Approved" documents have been posted this week to the SWGFAST website: 1) GLOSSARY, 2)  STANDARD FOR FRICTION RIDGE AUTOMATION TRAINING (LATENT/TENPRINT), 3) STANDARD FOR FRICTION RIDGE COMPARISON PROFICIENCY TESTING PROGRAM (LATENT/TENPRINT).

MINIMUM QUALIFICATIONS AND TRAINING TO COMPETENCY STANDARDS FOR FRICTION RIDGE EXAMINERS (LATENT/TENPRINT)


(To Replace:
Minimum Qualifications for Latent Print Examiner Trainees, ver. 2.1, Training to Competency for Latent Print Examiners, ver. 2.1, and Minimum Qualifications and Training to Competency Standards for Latent Print Examiners, ver. 1.0 Draft For Comment)

 

Preamble

This outline provides the recommended training program to achieve competency as a friction ridge examiner. The student must demonstrate knowledge of required objectives by successfully completing written tests and practical exercises. The student must also communicate an understanding of the objectives and underlying principles. It is also strongly recommended that students demonstrate knowledge of the supplemental objectives listed in this document.

 

Prior to becoming a friction ridge examiner, candidates shall possess a bachelor’s degree with science related coursework.

 

In addition to the objectives listed below, the examiner must achieve competency in the objectives outlined in the following SWGFAST documents: Standards for Conclusions and Friction Ridge Examination Methodology for Latent Print Examiners.

Instructors and mentors must have demonstrated competency in the topic areas they provide instruct.

 

The training period for a new trainee in the field of friction ridge examination shall consist of thorough training, continued testing, and apprenticeship (supervised casework) for the following duration:

 

Latent Print

Minimum: One year of full-time latent print work with the majority of the time spent on the analysis, comparison, and evaluation of impressions.

Recommended: Two years of full-time latent print work with the majority of the time spent on the analysis, comparison, and evaluation of impressions.

 

Tenprint

Minimum: Six months of full-time tenprint work with the majority of the time spent on the analysis, comparison, and evaluation of impressions.

Recommended: One year of full-time tenprint work with the majority of the time spent on the analysis, comparison, and evaluation of impressions.

 

1 Required Objectives

1.1 Program Qualitative and Time Requirements

1.2 Principles and Foundations

1.2.1 Understand the basic foundations for friction ridge examination (persistence and uniqueness) as a means of identifying the source of an impression.

1.2.2 Understand the biology and physiology of friction ridge skin.

1.2.3 Knowledge of the history of fingerprints.

1.2.4 Understand the use of fingerprints, palmprints, and footprints in criminal and civil applications.

1.3 Friction Ridge Pattern Recognition and Interpretation

1.3.1 Understand common terminology (e.g., arch, loop, and whorl) and definitions associated with friction ridge pattern recognition.

1.3.2 Understand pattern recognition and interpretation associated with operational needs of the individual agency.

1.3.3 Understand friction ridge formations as they relate to recognition, interpretation, and individualization.

1.3.4 Knowledge of the Henry Classification System.

1.3.5 Awareness of other classification systems (e.g., American, Vucetich, NCIC, and so forth).

1.4 Friction Ridge Examination (Analysis, Comparison, Evaluation, and Verification)

1.4.1 Understand the individual friction ridge structure (i.e., continuity, texture, pore, and edge definition) for determining the existence of individualizing details.

1.4.2 Ability to analyze friction ridge details to determine the value for comparison.

1.4.3 Ability to recognize and utilize friction ridge flow, scars, creases, and other friction ridge details for supporting the examination.

1.4.4 Ability to recognize and properly determine, when possible, the area from which the friction ridges originated.

1.4.5 Knowledge to properly analyze friction ridge impressions and understand effects such as processing technique, color reversal, pressure distortion, slippage, and overlays.

1.4.6 Ability to properly conduct a comparison.

1.4.7 Ability to render a proper and accurate conclusion.

1.4.8 Understand the necessity for verification by another competent friction ridge examiner.
