Pattern Evidence Training Announcement - Latent Print Examiner Training Program
NIJ Cooperative Agreement Award #2007-IJ-CX-K233
http://www.nfstc.org/news/announcements/docs/PatternEvidence/PE_Latent%20Print_announcement%2006_16_08.pdf

Offered to Selected Applicants

In partnership with the National Institute of Justice (NIJ), the National Forensic Science Technology Center (NFSTC) is pleased to announce that Latent Print Training will be provided at no cost to eligible applicants under Cooperative Agreement Award (#2007-IJ-CX-K233).

The training program will lead a cohort of entry level latent print examiner trainees through a series of course offerings designed to prepare participants for taking the International Association for Identification (IAI) certification examination. The Latent Print Examiner Training Program consists of 12 courses given in 6 two-week instructional sessions at the NFSTC training facilities in Largo, FL. Participants will be required to complete online course work and practical exercises between onsite course trainings.

The training is scheduled to begin in September 2008 and conclude July 2009.

KEPT - Keeping Examiners Prepared for Testimony - #27
Methodology Error Rate - Theoretical vs. Actual
by Michele Triplett, King County Sheriff's Office

Disclaimer:  The intent of this is to provide thought provoking discussion.  No claims of accuracy exist. 

 

Question – Error Rate of the Methodology:

What is the error rate for the ACE-V methodology?

 

Possible Answers:

a)      The error rate of the ACE-V methodology is zero.

b)      You can’t divide the error rate between the methodology and the practitioner because you can’t use the method without a human being.

c)      You can separate the practitioner error rate from the error rate of the methodology but these wouldn’t be actual error rates, they’d be theoretical error rates.

d)     I’m not aware of any research studies that have calculated an error rate for the methodology but the known errors over the last 100 years are extremely small (between 20 and 30 out of billions of comparisons).          

e)      I’m not aware of any research studies that have calculated an error rate for the methodology.  If this were to be done then there would be several error rates, 1 for type 1 errors, a rate for type 2 errors, a rate for clerical errors, a rate for the profession, a rate for an agency, and another rate for an individual.

f)       If you look at ACE-V as being synonymous with hypothesis testing then you can’t have an error rate because ACE-V isn’t a specific method, it’s more of a general guideline.  Error rates can only be calculated for detailed techniques.  Our profession doesn’t have an error rate for ACE-V but our overall error rate is known to be extremely low.

 

Discussion:

Answer a:  This is a common answer but it may not be the best answer.  There’s never been any research to support this answer.  If you use this answer, it’s very likely that the next question will be, “how did you arrive at this number”? 

Answer b:  This is another common answer but not very accurate.  Using any technique, method, or tool needs human intervention but other sciences manage to calculate the error rate of the tool and the error rate when a human uses the tool.  These error rates are commonly known as theoretical error rates and actual error rates. 

Answer c:  The error rate of a tool, independent of the practitioner, is known as a theoretical error rate.  The error rate of the tool being used by a human is usually higher than the theoretical error rate.

Answer d:  Judges have accepted this since it’s an estimate arrived at by using empirical data.

Answer e:  This may be an accurate answer but it’s a little more than what was asked for.  Sometimes if you give too much information then you lose the attention of the jurors.  Once you lose the juries interest, it’s very hard to get it back.

Answer f:  Daubert doesn’t require that we know the error rate of the method, just an error rate in applying the method.  This answer is good because it brings the conversation back to a more relevant topic.
