OSAC Lexicon
The OSAC Lexicon is a compendium of forensic science terms and definitions. This terminology tool was created to help bring consistency and understanding to the way terms are used by the various forensic science. Use of the OSAC Lexicon does not replace the need to reference the original published source.
The terms and definitions in the OSAC Lexicon come from the published literature, including documentary standards and technical reports. It is continually updated with the latest work from OSAC units, as well as terms from newly published documentary standards and standards elevated to the OSAC Registry.
Gradually terms are evaluated and harmonized by the OSAC to a single term. This process results in an OSAC Preferred Term. An OSAC Preferred Term is a term, along with its definition, that has undergone review and evaluation by the FSSB Terminology Task Group and has been approved by the FSSB. The FSSB recommends that subcommittees use OSAC Preferred Terms when drafting standards.
The OSAC Lexicon should be the primary resource for terminology and used when drafting and editing forensic science standards and other OSAC work products.

Certification
Certification is the recognition that a canine-handler team has acquired and demonstrated specialized knowledge, skills, and abilities in the standard practices necessary to execute the duties of a canine team. Certification also provides the fire investigator a means of identifying those canine-handler teams that have successfully demonstrated compliance with established requirements. In addition, certification establishes that a canine-handler team achieves and maintains proficiency.

Change Of Behavior (Cob)
A characteristic pattern of behaviors, as recognized by the canine handler that occurs when the canine detects a trained scent. This differs from other olfactory interest that otherwise are exhibited by the canine in response to the daily environment. The initial change of behavior typically leads to following the scent to its source/target. The pattern of behavior may be unique to each canine.
