The OSAC Registry is a repository of selected published and proposed standards for forensic science. These documents contain minimum requirements, best practices, standard protocols, terminology, or other information to promote valid, reliable, and reproducible forensic results.
The standards on this Registry have undergone a technical and quality review process that actively encourages feedback from forensic science practitioners, research scientists, human factors experts, statisticians, legal experts, and the public. Placement on the Registry requires a consensus (as evidenced by 2/3 vote or more) of both the OSAC subcommittee that proposed the inclusion of the standard and the Forensic Science Standards Board.
OSAC encourages the forensic science community to implement the published and proposed standards on the Registry to help advance the practice of forensic science.
The OSAC Registry includes two types of standards:
Anthropology | Biology/DNA | Bloodstain Pattern Analysis | Crime Scene Investigation | Digital Evidence | Dogs & Sensors | Facial and Iris Identification | Fire & Explosion Investigation | Fire Debris & Explosives | Firearms & Toolmarks | Footwear & Tire | Forensic Document Examination | Friction Ridge | Gunshot Residue | Medicolegal Death Investigation | Odontology | Seized Drugs | Speaker Recognition | Toxicology | Trace Evidence | Video/Imaging Technology & Analysis | Wildlife Forensics | Interdisciplinary
