Learn More About the Organization of Scientific Area Committees (OSAC) for Forensic Science

The Organization of Scientific Area Committees (OSAC) for Forensic Science works to strengthen the nation’s use of forensic science by facilitating the development of technically sound forensic science standards and by promoting the adoption of those standards by the forensic science community.

These standards are written documents that define minimum requirements, best practices, standard protocols, and other guidance to help ensure that the results of forensic analysis are reliable and reproducible.

OSAC is administered by the National Institute of Standards and Technology (NIST), but the great majority of its more than 550 members are from other government agencies, academic institutions, and the private sector. These members have expertise in twenty-five specific forensic disciplines, as well as general expertise in scientific research, measurement science, statistics, law, and policy.

PCAST Report -- Forensic Science in Criminal Courts: Ensuring Scientific Validity of Feature Comparison Methods

PCAST Report

PCAST, the President's Council of Advisors on Science and Technology, released a report on September 20, 2016, discussing the role of scientific validity in the legal system. The report, Forensic Science in Criminal Courts: Ensuring Scientific Validity of Feature-Comparison Methods, evaluated validity of seven areas:

  • DNA analysis of single-source and simple-mixture samples
  • DNA analysis of complex-mixture samples
  • Bitemark anaysis
  • Latent fingerprint analysis
  • firearms analysis
  • footwear anaylsis
  • hair analysis
  • The report concludes by making several recommendations to the National Institute of Standards and Technology (NIST), the Organization for Scientific Area Committees (OSAC), the FBI Laboratory, the U.S. Attorney General, and the Judiciary.

    Several organizations responded to the PCAST Report, including:

    A new grant in the amount of $400,000 was awarded to Stetson University College of Law for the National Clearinghouse for Science, Technology and the Law (NCSTL) to develop a forensic evidence training program for lawyers who work on death penalty cases. “This training program is crucial at a time when life or death often hinges on the presentation of forensic evidence in the courtroom,” said NCSTL Founding Director and Professor of Law Carol Henderson.

    The grant, awarded by the U.S. Attorney General as part of the Adjudication and Law Enforcement National Initiatives, will support the development of a “Crime Scene to Courtroom Forensics” program. The new training program will provide in-person and webinar training on forensic science evidence and the use of expert testimony.

    “Training in forensic evidence is essential to improve the quality of legal representation and to ensure reliable jury verdicts,” said Henderson. Stetson’s National Clearinghouse was developed to foster communication between the scientific, technological and legal communities, providing comprehensive scientific, technological and legal information to promote justice based on sound science and technology. The NCSTL has trained more than 13,500 legal and scientific professionals since its inception in-person and online. The NCSTL has released the following CLE/CE Programs: SANE-SART Training for Forensic Nurses, A Collaboration Between NCSTL and SANE-SART Resource Services, Law 101: Legal Guide for the Forensic Expert, sponsored by National Institute of Justice (NIJ), housed on, billed by NIJ as "one of the most popular courses EVER", Forensic Science Course for Capital Litigators - Self-Study which focuses on forensic science. Legal Guide for the Forensic Expert has been a very popular course published on two years ago.

    Under grants from the Bureau of Justice Assistance (BJA), NCSTL has conducted many training in-person workshops on the use of forensic science in capital cases over the past several years. See Education and Training Section of this website. In 2016, two more in-person workshops will be conducted for prosecutors and defense attorneys - who litigate capital cases.

    This Web site is funded in whole or in part through a grant from the Bureau of Justice Assistance, Office of Justice Programs, U.S. Department of Justice. Neither the U.S. Department of Justice nor any of its components operate, control, are responsible for, or necessarily endorse, this Web site (including, without limitation, its content, technical infrastructure, and policies, and any services or tools provided).
