Common questions
What is SWGFAST and what did it do?+
SWGFAST (Scientific Working Group for Friction Ridge Analysis, Study and Technology) was an FBI-convened standards body that operated from 1995 to 2014. It created foundational documentation for fingerprint examination, including the ACE-V methodology, training requirements, and terminology that US fingerprint examiners follow.
How does SWGFAST relate to ACE-V?+
SWGFAST published the foundational ACE-V (Analysis, Comparison, Evaluation, Verification) methodology documents starting in 1995. ACE-V remains the standard approach for friction ridge analysis in US forensic labs.
What happened to SWGFAST after 2014?+
SWGFAST dissolved in 2015, and its standards-setting role transferred to the OSAC Friction Ridge Subcommittee. From 2013 onward, SWGFAST had also begun publishing guidance on contextual bias management for examiners.
