Methodology
IDEA v3 published
Version 3 of the IDEA standard is published in full. It is the version against which engagements are assessed.
Assay Foundation has published version 3 of the IDEA standard, against which independent Assayers assess AI implementation engagements. The standard, its seven-gate operational schedule and its acceptance criteria can be read in full. No version is held back from the people the scheme serves.
Version 3 consolidates changes opened for public consultation in autumn 2025. The main additions concern the Test & Acceptance gate, which now sets out the calibration and fairness evidence an Assayer must record, and the Operation gate, which now requires a defined monitoring interval rather than a single check at acceptance.
Every Register record will state the version of IDEA the engagement was assessed against, so the meaning of a Hallmark is fixed on the date it was issued and does not drift as the standard develops.
The next consultation window will be announced in a Notice. Changes are proposed, opened for comment and reconciled in the open before they are adopted.
