What are the five indicators of confidence?
They are asserted, basic, standard, enhanced and strict. The published framework sets the five labels without fixing their technical characteristics. The public working draft of the benchmarking part gives external accuracy benchmarks for four of them, from ninety per cent to ninety-nine point nine nine per cent.
The labels in plain words
Asserted is a self-declared age with no validation. Basic is the first measured level. Standard sits in the middle. Enhanced and strict are high claims that need large samples, a controlled method and a stated attack potential.
The benchmarks are a draft reference
The figures come from a public working draft, not a published requirement. They are useful for planning a test and for reading a supplier's claim, and they should be confirmed against the published edition before a contract depends on them.
How to use them without overstating
Put the indicator beside every accuracy figure. State the threshold, the challenge age and the class balance. A figure without the indicator cannot be compared with another supplier's figure, and a high indicator without a large enough sample is a label rather than a measurement.
What a policy maker can add
The framework allows a policy maker to subdivide the indicators for a use case. A regulator can set a stricter threshold for a higher-risk service, and a comparison should use the policy's threshold rather than the draft's generic figure.
Not legal advice; does not certify. The draft is a guidance document in ballot. Check the published text before a decision depends on it.
