What is an Aon test?

An Aon test is an online psychometric test from Aon's assessment business, built on the cut-e test range Aon acquired in 2017. It spans the scales ability tests, short timed measures of numerical, verbal and abstract reasoning, the smartPredict gamified assessments, and the ADEPT-15 personality questionnaire. The tests are mobile friendly, delivered in more than 40 languages, and around 30 million assessments are administered each year.

Which Aon test you sit depends on the employer and the role: an entry-level position will not be given the same assessment as a graduate or managerial one.

How an Aon test works

Four things to know before you sit one. Timings and difficulty vary with the level of the role.

FormatShort modular tests
Each Aon test measures one aptitude and lasts 2 to 20 minutes, so an employer strings several together. Every test opens with a short instruction video and a few untimed practice questions before the clock starts.
PaceAs many as you can
Most scales tests give you more questions than anyone finishes. The score is how many you get right in the time, so unanswered questions at the end are expected, not a failure.
DifficultySeveral tests adaptive
Answer well and the next questions get harder; the level of the test is set to the role, so a graduate sitting is harder than an entry-level one.
ScoringA percentile against the employer's bar
There is no fixed pass mark. Your result is a position against a comparison group and each employer sets its own threshold for the role.

Based on 784 completed practice sittings, all time. Checked 11 September 2026.

The 75th percentile marks the boundary of the top quarter of recorded scores; tied scores can share that boundary. These are our practice results, not employer pass marks.

How we calculate these figures

We use all-time completed, scored attempts at this practice test. Repeat attempts count separately, so the sample is sittings rather than unique people.

The average is the mean score across those sittings. The 75th percentile comes from their recorded score distribution. The “checked” date is when we retrieved the figures, not the period when the tests were taken.

How an Aon sitting runs

Aon tests are online, timed and taken one at a time, each measuring a single aptitude. They fall into three groups: performance tests of reasoning and memory, skills tests such as language and numeracy, and personality questionnaires. An employer picks the tests that match the role, so a finance applicant might sit scales numerical, scales verbal and chatAssess while an engineering applicant sits scales mtu instead.

At the start of each test a short introductory video explains the task and the time limit, and you answer a few untimed questions to confirm you have understood before the clock starts. The table above gives the question count and time limit for each named test.

Frequently asked questions

What candidates ask us most often

Is an Aon assessment the same as a cut-e test?

Yes. Aon acquired cut-e in 2017 and the tests are unchanged, so an invitation may say Aon, cut-e or mapTQ, the portal the tests run on, and mean the same thing. The cut-e guide covers the same tests under their older name.

What happens at the start of an Aon test?

A short video explains the task and the time limit, then you answer a few practice questions to show you have understood. That part is untimed, so take it slowly; the clock only starts on the real questions.

What if you do not finish an Aon test?

On most scales tests nobody does. They give you more questions than the time allows and score how many you answer correctly, so keep a steady pace rather than rushing to reach the end. On the true, false or cannot say tests a wrong answer is worse than a skipped one.

Can you retake an Aon assessment?

Each employer sets its own retake policy, and most ask you to wait a set period before sitting the same test again. Ask the recruiter before you start if it matters to you.

Which employers use Aon assessments?

The employers listed above name Aon or cut-e in their own processes; Aon says its tests are used in 90 countries, notably in aviation, financial services and graduate hiring. If your employer is not listed, its employer guide says which assessment sits at which stage.
