This guidance note is endorsed by the Forensic Imagery Analysis Group (FIAG) within the British Association of Human Identification (BAHID). These notes are non-binding on practitioners and it is the strong opinion of the group that it is the expert’s professional duty to evaluate each case independently and draw conclusions based upon this guidance note, their own professional experience and any prevalence statistics or other evidence that is relevant to the case and contained within, or referred to, in their report.

For each of the levels of support, it is not possible to indicate a specific number of required similarities as the factors of most importance differ from case to case. The levels of support should not be seen as a ‘stepped’ or mutually exclusive set of categories but rather a continuous spectrum whereby each level blends into the next and no distinct cut-off point can be defined.
