What is the HFHE report?

The Forensic Handwriting Examination and Human Factors: Improving the Practice Through a Systems Approach report, or just the HFHE Report, was produced by the Expert Working Group for Human Factors in Handwriting Examination.

I was fortunate to be invited to be a part of this expert working group. The membership spanned various scientific disciplines and included forensic document examiners, lawyers, cognitive scientists (including human factors specialists), among others.  A more lengthy discussion of this can be found here.

The EWG “…conducted a scientific assessment of the effects of human factors on forensic handwriting examination” and produced a report that “…provides a comprehensive discussion of human factors as they relate to all aspects of handwriting examination, from documenting discriminating features to reporting results and testifying in court.” Of course, the report also provides extensive recommendations aimed at improving the practice in the future.  Specifically, the work was produced “…to encourage and enhance efforts to apply human factors principles to forensic science applications, reduce the risk of error, and improve the practice of forensic handwriting examination.”

It should be noted that the EWG was supported by the National Institute of Justice (NIJ), Office of Investigative and Forensic Sciences (OIFS), and the National Institute of Standards and Technology (NIST) Special Programs Office.

How long does an examination take?

The time required for a case depends on the number of items involved, as well as what needs to be done (ie., the number of requests made and the number of comparisons or examinations to be done). However, assuming the case isn’t too large and the quality of samples is reasonable, turnaround times are usually within 5-10 business days from receipt of evidence to return of evidence with a verbal report of findings. Written report will generally take a few more days. Complex matters, such as medical record reviews or examinations involving multiple potential writers, will require additional time, sometimes considerably more. If your samples have limitations it may be necessary to obtain more or better items in which case the time frame will extend. An estimate for the expected completion date will be provided once a case has been submitted and reviewed.
