The first version of the standard, ANSI/NBS-ICST 1-1986 was published by NIST (formerly the National Bureau of Standards) in 1986. It was a minutiae-based standard. Revisions to the standard were made in 1993, 1997, 2000, and 2007.Updates to the standard are designed to be backward compatible, with new versions including additional biometric modalities and associated data. All of these versions use "Traditional" encoding.
In 2008, XML encoding of the standard was introduced, based upon the 2007 version. The 2007 and 2008 versions of the standard were designed to be the same except for the encoding. The XML encoding was developed using the naming conventions of the National Information Exchange Model (NIEM). Thus, this encoding is referred to as "NIEM-conformant XML."
In 2009, a minor supplement to the 2007 and 2008 versions was approved that extended the codes for friction ridge images to include multiple finger capture.
In November, 2011 a new version of the standard was approved. This version is focused on the content of the transmission, with encoding rules handled as annexes. Thus, there is no need for separate versions of the standard as was the case for 2007 (Traditional format) and 2008 (NIEM-conformant XML). The 2011 version of the standard also includes additional modalities (DNA and plantar) as well as the extended feature set (EFS) for Type-9 record; forensic image markups for face and iris; new metadata fields such as geoposition of sample collection; biometric data hashing; an information assurance record; associated context record; original source record and data handling logs; images of all body parts in the Type-10 record and more. Current plans are to extend the standard to include records types for voice recognition and dental forensics / bitemark analysis as well as an annex for conformity assessment.
In 2013, the standard was updated to ANSI/NIST-ITL 1-2011:Update 2013. The Forensic Dental and the Forensic and Investigatory Voice Supplements were approved.
In 2015, the standard was updated to ANSI/NIST-ITL 1-2011:Update 2015.
