Aon (cut-e) tests: the employers that use them, and why the clock feels shorter

Aon bought cut-e in 2017 and its tests now arrive under the Aon name. They are short, tabbed and fast, and some are games. These are the employers on this site that name Aon, and what their pages say about it.

The tabbed format and the game-like tests

Prep sites consistently describe Aon's scales numerical and scales verbal tests as tabbed: the information you need is split across several tabs, and part of the test is finding the right one quickly. Questions come one after another under a short overall clock, so the skill is navigation plus reading, not long calculation.

Aon also runs game-like tests. Prep sites describe switchChallenge as a deductive logic task where symbols pass through switches that reorder them, and gridChallenge as a spatial and short-term memory task. Network Rail and Schroders, both on this site, name Aon as their testing partner.

Guessing can cost more than leaving a gap

Several prep sources say some Aon cognitive tests penalise wrong answers, so a run of blind guesses in the last minute can lower your result. Sources disagree, and Aon does not publish the rule on any page we read. The safe habit is to answer quickly where you are confident and avoid pure guessing.

Results are compared with a norm group the employer selects. No employer we cover publishes its cut-off, and figures you may see on prep sites are not backed by any source we could verify.

What to practise first

Start with the numbers. Reading a table and doing one percentage step quickly is the core of the scales numerical test, and it is the skill most applicants lose points on. Our numerical reasoning test drills it under time.

For the logic games, the best practice is noticing a rule from a few examples. Our abstract reasoning test trains that. Employers such as Network Rail also point candidates to Aon's own practice material, which is the closest thing to the real interface.

Set-up matters more than usual

Tabbed tests are harder on a phone. Sit them on a laptop with a mouse, close other tabs, and keep paper and a calculator nearby if your invitation allows one. Some employers remotely invigilate Aon tests, so check what software you need the day before rather than five minutes before.

Aon tests often arrive in a bundle with a personality or situational questionnaire. Do those honestly and first if you can choose the order, so the timed tests get your freshest attention.

Frequently asked questions

Is cut-e the same as Aon?

Yes. Aon acquired cut-e and its tests are now delivered under the Aon name. Prep sites still use both names.

Which employers use Aon tests?

The table lists every employer page on this site that names Aon, with whether the employer states it or candidates report it. Network Rail and Schroders state it.

Are Aon tests negatively marked?

Some prep sources say wrong answers can count against you on certain Aon tests. Aon does not publish the rule on pages we read, so avoid blind guessing.

What is switchChallenge?

Prep sites describe it as a deductive logic game where you work out which switches reorder a set of symbols. Practise spotting rules from a few examples.

Can I take an Aon test on my phone?

Often you can, but tabbed questions are easier on a laptop. Check your invitation for device rules and invigilation software.

Is LifeScore affiliated with Aon?

No. LifeScore is not affiliated with Aon, cut-e or any employer listed here. Our questions are original.
