; (B) accuracy or bias reports required under this Act; (C) each probe image that was used by the agency; (D) any modifications made to the probe image; (E) the candidate list, in rank order, produced by the facial recognition system; and (F) any other police documentation related to the use of facial recognition in the law enforcement investigation. (b) Language requirement The information required under subsection (a) shall be provided to such individual in an appropriate language for such individual if the individual is not fluent or literate in English. II Certain requirements and limitations on facial recognition systems and research 201. National Institute for Standards and Technology assistance (a) In general The National Institute of Standards and Technology (hereinafter in this section referred to as NIST ) shall— (1) develop best practices for law enforcement agencies to evaluate the accuracy and fairness of their facial recognition systems; (2) develop and offer an ongoing benchmark facial recognition test for law enforcement that— (A) conducts evaluations of actual algorithms used by law enforcement agencies; (B) uses the types of probe images, including in terms of quality, actually used by law enforcement agencies in its testing; (C) evaluates algorithms on larger databases that reflect the size of databases actually used by law enforcement; and (D) evaluates whether the accuracy of a facial recognition algorithm varies on the basis of race, ethnicity, gender, or age and assessments of bias in facial recognition systems; (3) develop an operational testing protocol that independent testers and law enforcement agencies may implement for annual operational testing to determine— (A) the accuracy of the facial recognition system; (B) the impact of human reviewers on facial recognition system accuracy; and (C) whether the accuracy of the facial recognition system varies significantly on the basis of race, ethnicity, gender, or age
