What is Critical Reasoning?
Critical Reasoning is evaluating an argument rather than a claim — naming the assumption it rests on, the evidence that would strengthen or weaken it, and the flaw that makes a plausible conclusion unsound. The material is deliberately unfamiliar, so the score reflects analysis rather than whether the reader already agrees.
Critical Reasoning is one of 11 competencies in the AssessAll Aptitude Competency Set — the scoring layer every AssessAll aptitude instrument reports against. What a person can work out, rather than what they have already learned — the reasoning, comprehension, precision and pace that the AssessAll aptitude instruments report a band against. It is a separate published set from the 29 behavioural competencies of the AssessAll Capability Framework, and we say so rather than presenting one number of competencies: an ability you can test in twenty minutes and a behaviour colleagues observe over a year are not the same kind of thing.

What critical reasoning 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.
Arguments persuade you by tone; assumptions and flaws mostly go unnoticed.
You spot obvious flaws but subtle assumption gaps and scope shifts still slip past.
You dissect arguments into claim, evidence and assumption, and judge them soundly.
You evaluate reasoning with rigour — separating correlation from cause and evidence from assertion instinctively.
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.
- Rejects a conclusion by disputing the source rather than the inference, which leaves a bad argument from a trusted source untouched.
- Accepts a correlation once a mechanism is attached to it, and does not ask what else moved in the same period.
- Cannot state the single assumption their own recommendation needs to be true.
Evidence to look for
You cannot interview for an ability. Asking somebody whether they are good with numbers, or careful with detail, measures their self-image and their confidence, and both are poor proxies. What an interview can do is send you to the work. Each prompt below points at something the person actually produced — the evidence is in the artefact, not in the answer.
- A recommendation they wrote: ask which one assumption, if false, kills it — and whether that assumption appears anywhere in the document.
- A vendor claim they evaluated — what evidence did they ask for that was not volunteered?
- A decision they argued against and lost: does the objection still hold, and on what grounds rather than on what happened?
These are work-sample 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.
- For every argument you read, write its conclusion, evidence and the unstated assumption in three lines.
- Practise strengthen/weaken items and always ask: what fact would break this link?
- Learn the common flaw families — sampling, causation, false dilemma, scope shift — and hunt one each day.
What measures critical reasoning on AssessAll
Every form below reports a band for this competency. Item counts and time limits are the configured values, published here because they are the two numbers that decide what a score means and the two that vendors most often leave off a product page — a form with 20 items in 10 minutes and a form with 20 items in 25 minutes are not measuring the same thing.
| Assessment | Items | Minutes | Seconds / item | What it is for |
|---|---|---|---|---|
| Critical Reasoning & Argument Evaluation | 18 | 30 | 100 | The core form; 100 seconds an item, deliberately a power format |
| Business Case Analysis | 14 | 30 | 129 | Applied to a business case; reports Workplace Judgment too |
| Verbal Reasoning — Professional | 20 | 22 | 66 | Argument evaluation inside a verbal form |
| Commercial Judgment & Market Sense | 16 | 26 | 98 | Commercial reasoning; reports Workplace Judgment first |
Seconds per item is arithmetic on the two published columns, not a separate claim. Read it as the working pace the form assumes: under about 45 seconds an item, pace is part of what is being measured whether or not the product says so. See speeded test for why that distinction changes how the score should be read.
Often confused with Critical Analysis
Critical Analysis is the behavioural competency in the AssessAll Capability Framework — how a person interrogates evidence in their own work, observed over weeks. Critical Reasoning is the aptitude measure — a timed judgement about arguments on unfamiliar material. The first is observed by colleagues; the second is tested. They are different pages because they are different instruments.
Critical AnalysisHow AssessAll measures it
Critical Reasoning 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.
Aptitude items are multiple-choice and machine-scored against a key, so the band is reproducible and the whole form can be sat in under half an hour. That is the trade: an ability score is cheap, fast and comparable, and it tells you what somebody can work out — not what they will choose to do, which is what the behavioural competencies are for. Read one band beside the other rather than either alone, and browse the assessment catalogue or the store for the forms above.
How critical reasoning aligns to public frameworks
Two rows, not five, and the absence is the honest part. O*NET publishes a taxonomy of cognitive abilities and the UK Civil Service Success Profiles carries an Ability element, so there is something real to align to in both. Australia's Integrated Leadership System, Canada's Key Leadership Competencies and ESCO's transversal skills are behavioural and occupational frameworks that contain no cognitive-ability elements — so this page leaves those rows out rather than inventing a correspondence. Alignment, not derivation; no proprietary instrument is reproduced.
| Framework | Corresponding element |
|---|---|
| O*NET | Abilities: Inductive Reasoning (1.A.1.b.5), Deductive Reasoning (1.A.1.b.4); the applied form corresponds to the O*NET Skill Critical Thinking rather than to a single ability |
| Civil Service Success Profiles | Success Profiles: Ability |
