Thinking & Judgment · Competency Dictionary
What is Data-Informed Judgment?
Data-Informed Judgment is reading evidence honestly and using it to sharpen judgment rather than replace it. It requires knowing what a measure can and cannot support — the sample size, what the metric truly counts, and the point where the data runs out and a considered human decision has to take over and be owned.
Data-Informed Judgment is one of 29 competencies in the AssessAll Capability Framework, in the Thinking & Judgment domain — How a leader thinks — framing problems, choosing between imperfect options, and reading evidence honestly.

What data-informed judgment looks like at four levels
Every AssessAll competency score is reported on a 0–100 scale and interpreted against four published anchors. The wording below is the same interpretation a person receives in their own report — published here so a manager can read a score without needing one.
You either lean on gut over data or take numbers at face value without questioning them. Either way, a little fluency in base rates and what the data is and isn't saying would meaningfully improve your calls.
You use data when it's handed to you but don't always interrogate it or notice when it's misleading. The growth is in asking better questions of the numbers.
You read data critically, weight it against context and base rates, and use it to inform judgement rather than outsource it.
You're fluent in the honest reading of data — spotting base-rate neglect, selection effects, and false precision — and you blend it with judgement to make decisions others can't.
Signs it is missing
Competencies are easier to spot by their absence. These are observable behaviours, not personality judgements — each one is something a colleague could describe from memory.
- Quotes a percentage from a sample too small to carry it, without ever naming the sample.
- Uses data as cover: the analysis appears after the decision, to justify it.
- Refuses to decide until the data is conclusive, on questions where it never will be.
Evidence to look for
Questions that make a person describe what they actually did, rather than what they believe about themselves. Use them in an interview, a development conversation or a promotion panel, and listen for a specific situation, a specific action and a cost.
- Show me a decision you made against what the dashboard suggested. What did you know that it did not?
- What is the smallest sample you would act on, and why that number?
- Which of your regular metrics would you stop reporting, and what would you replace it with?
These are interview and observation prompts written for this page. They are deliberately not items from a live AssessAll instrument — published items stop measuring anything.
How to develop it
The development moves AssessAll puts in a growth plan when this competency is a person's priority area. Each is small enough to start this week.
- On your next metric, ask 'compared to what?' and 'what's the base rate?' before drawing a conclusion.
- Find one number your team treats as gospel and pressure-test how it's actually calculated.
- Practise stating what a dataset cannot tell you, alongside what it can.
How AssessAll measures it
Data-Informed Judgment is not measured by a single question. Responses across an assessment map to the competency, roll up into a 0–100 score, and are interpreted against the four anchors above. Because every AssessAll assessment speaks the same competency language, results from different instruments accumulate into one profile rather than a pile of unrelated scores.
Which instrument is appropriate depends on the decision you are making. Situational judgement items suit judgement-under-pressure competencies; structured behavioural evidence and multi-rater feedback suit the ones only other people can see. See how to assess leadership skills for the item types, or browse the assessment catalogue and the store.
How data-informed judgment aligns to public frameworks
The AssessAll Capability Framework is an original work. The table shows what this competency corresponds to in five public government and standards frameworks, so a result travels across borders. Alignment, not derivation — no proprietary instrument is reproduced.
