Cognitive ability tests: what they measure, example questions and how to prepare
A cognitive ability test is a timed set of questions that measures how well you reason with new information. Employers use it to compare candidates on the same footing. Below: the main types with an example of each, how results are scored and how to prepare.
What is a cognitive ability test?
A cognitive ability test is an assessment of how effectively you process information, solve problems and draw conclusions. It is usually multiple choice, taken online and strictly timed, and it tests reasoning rather than specialist knowledge. You do not need to know anything about the job to answer the questions.
Employers favour these tests because every candidate gets the same questions under the same conditions, which makes results easy to compare across a large group of applicants.
What does it measure?
- Reasoning with new information: spotting rules and relationships you have not seen before.
- Verbal comprehension: understanding written text and judging what follows from it.
- Numerical reasoning: working with figures, percentages, tables and charts.
- Speed and accuracy: keeping your error rate low while the clock runs.
The main types, with an example of each
Verbal reasoning
You read a short passage and decide whether a statement is true, false or cannot be determined from the passage alone.
Example.Passage: “All reports submitted before noon are reviewed the same day. The finance report was submitted at 11:40.” Statement: “The finance report is reviewed the same day.” Answer: True. 11:40 is before noon, so the rule applies.
Numerical reasoning
You pull figures from a table or chart and calculate, usually with percentages, ratios or averages.
Example. A department budget rises from 80,000 to 92,000. What is the percentage increase? Answer: 15%. The increase is 12,000, and 12,000 ÷ 80,000 = 0.15.
Abstract reasoning
You find the rule behind a sequence of shapes or symbols and apply it to the next step. Real tests use shapes, but the logic can be shown with letters.
Example. What comes next: A, C, F, J, O, ? Answer: U. The gaps between letters grow by one each time (+2, +3, +4, +5), so the next gap is +6.
Some tests add logical or deductive reasoning, spatial reasoning, or error-checking sections. The three types above are the most common, and the ones EPSO uses.
How scoring works
A result can be reported as a raw score (questions correct), a percentile compared with a norm group, or a pass or fail against a set mark. Employers often combine them: a pass mark first, then a ranking of those who passed. Our guide what is a good score on a reasoning test explains the difference and how to read your own practice results.
How to prepare
- Learn the formats first. Most lost points come from misreading the question type, not from lack of ability.
- Practise under the clock. Time per question is the main difference between practice and the real thing.
- Review every mistake. Name the cause, a misread, a calculation slip, a wrong method or a timeout, and fix the most frequent one.
- Train all three types, then give extra time to your weakest.
- Practise often in short sessions instead of one long session the night before.
Cognitive ability tests in EPSO competitions
EPSO, the EU's selection office, uses verbal, numerical and abstract reasoning tests in its competitions. In the AD5 2026 competition they are multiple choice, online and proctored: 20 verbal questions in 35 minutes, 10 numerical in 20 minutes and 10 abstract in 10 minutes, each with a pass mark. The full numbers are in EPSO reasoning tests: scoring and pass marks.
Cognitive ability tests: FAQ
What does a cognitive ability test measure?
It measures how well you reason with new information under time pressure. Typical areas are verbal reasoning, numerical reasoning and abstract (pattern) reasoning, sometimes with logic, spatial or speed-and-accuracy sections.
Is a cognitive ability test the same as an IQ test?
They overlap, because both aim to capture reasoning ability, but they are not the same. Employer tests are usually shorter, timed, and built around work-relevant reasoning rather than producing a full IQ score.
How long does a cognitive ability test take?
It varies by test. Many employer tests run from a few minutes per section to under an hour in total. The EPSO AD5 2026 reasoning tests, for example, take 35 minutes (verbal), 20 minutes (numerical) and 10 minutes (abstract).
Can you prepare for a cognitive ability test?
Yes. You cannot change your underlying ability in a few weeks, but familiarity with the question types, a sound method and time management reliably improve results, and timed practice makes the real test feel less unfamiliar.
What is a good score on a cognitive ability test?
It depends on the employer: either a pass mark you must reach, or a ranking against other candidates. Raw score, percentile and pass mark mean different things, which we explain in a separate guide.
