- AON refers to Aon Assessment, the testing division formed after Aon plc acquired cut-e in May 2017.
- There is no candidate fee - the hiring employer licenses the assessment, not the applicant.
- Modules run 2 to 15 minutes each, drawn from scales tests, smartPredict games, and personality instruments.
- Scoring is percentile-based against norm groups; each employer sets its own benchmark, not Aon.
Where "AON" Comes From in This Context
Search "AON" and you'll find several unrelated credentials sharing the same three letters - insurance certifications, network protocols, financial designations. On this site, and in this article specifically, AON means Aon Assessment, the pre-hire testing platform published by Aon Assessment Solutions. This is the business unit Aon plc created after it acquired the Hamburg-based company cut-e in May 2017. If you were invited to take an online test and the email or job advert mentioned "cut-e," you were looking at the exact same assessment family - the cut-e name simply persists in some older invitation templates.
Understanding this distinction matters because the wrong "AON" carries wrong facts: different exam fees, different certifying bodies, different pass thresholds. None of that applies here. If you landed on this page confused about which AON you're dealing with, our companion piece on What Is AON? walks through the same identification process in more depth, and AON Meaning covers the terminology from a slightly different angle.
What AON Actually Refers To
Aon Assessment is not a single exam with one score and one pass mark. It's a modular battery - a toolkit of short tests that employers mix and match depending on the role they're hiring for. A candidate never takes "the AON exam" in the singular sense; they take whichever combination of modules the employer selected, typically delivered as one continuous online session after an invitation email.
For a broader orientation to the platform before diving into module specifics, see What Is AON Certification? and the general overview at AON Certification.
How the Assessment Is Administered
Because Aon owns and operates its own browser-based testing platform, there is no third-party proctoring vendor involved - no Pearson VUE, no PSI, no Prometric booking system. You won't schedule a testing center appointment. Instead:
- An employer sends a direct invitation link, usually with a window of five to ten days to complete the modules.
- There is no candidate fee. The employer licenses the assessment battery from Aon, so the cost sits entirely on the hiring organization's side.
- Testing typically happens unsupervised, from your own device, within the invitation window.
Because there's no exam center fee structure like traditional certifications, questions about "how much does AON cost" have a different answer than you might expect - see AON Certification Cost 2026: Complete Pricing Breakdown for the full breakdown of who actually pays and when.
Key Takeaway
If someone asks you for payment to "register" for an Aon Assessment, that's a red flag - the employer already covers licensing, and candidates are never billed directly.

The Modules Behind the AON Name
What actually makes up an "AON test" is a selection from three families: scales ability tests, smartPredict gamified challenges, and behavioral/personality instruments. Each has published time limits, and none of them run long - most modules finish in well under 15 minutes.
scales verbal (47 questions, 12 minutes)
Reading comprehension and statement evaluation under heavy time pressure. This is one of the two highest-volume modules in graduate and financial-services hiring.
- Speed of reading matters as much as accuracy
scales numerical (37 questions, 12 minutes)
Data interpretation from tables, charts, and short numerical problems.
- Most candidates cannot reach half the items - pacing strategy is essential
scales cls - inductive-logical reasoning (12 tasks, 12 minutes)
Pattern and rule-based logic tasks that test abstract reasoning rather than domain knowledge.
scales ix - inductive reasoning (20 questions, 5 minutes)
A short, fast module focused on identifying underlying rules in sequences.
Beyond these, the battery can include scales eql (basic numeracy, 5 minutes), scales lt (language skills, 10 minutes), scales verbal instruct (24 questions, 8 minutes), and mechanical reasoning (24 questions, 15 minutes). The smartPredict side brings gamified challenges: switchChallenge (deductive reasoning), gridChallenge (working memory, 9 tasks in 9 minutes), motionChallenge (complex planning), digitChallenge (numeracy), and clx, each running around 5-6 minutes. chatAssess (situational judgement, 15 minutes) and ADEPT-15 (Adaptive Employee Personality Test, 20 minutes of test time, 23 with instructions) round out the behavioral side.

Who Sends You an AON Invitation
You typically encounter Aon Assessment modules when applying to large, structured graduate schemes or financial-services roles - sectors where high applicant volume demands standardized, scalable screening. Because the platform operates in over 90 countries and 40-plus languages, it's common at multinational employers running the same hiring process across regions simultaneously.
If your invitation email still references "cut-e," don't panic - it's the same Aon-owned platform, just an older brand name that hasn't been fully retired from every template. The modules, timing, and scoring logic are identical either way.
Curious what roles typically use this screening step and how it fits your career path? AON Jobs covers the hiring contexts in more detail, and AON Requirements 2026: Eligibility, Prerequisites & How to Qualify explains what, if anything, you need before you're invited.
Why There's No "AON Score" to Chase
One of the most common misunderstandings is treating Aon Assessment like a certification exam with a fixed passing score. It isn't. Scoring works on a percentile basis against norm groups - your performance is compared to a reference population, not measured against an absolute cutoff.
| Feature | Traditional Certification Exam | Aon Assessment |
|---|---|---|
| Passing score | Fixed numeric threshold | No universal pass mark; percentile-based |
| Who sets the bar | Certifying body | Each individual employer |
| Retake policy | Set by testing body | Set by the employer, not Aon |
| Candidate fee | Often required | None - employer licenses the test |
This has real implications: two candidates with identical raw scores could get different outcomes at different companies, because each employer decides its own benchmark. For the full mechanics of how this works, read AON Passing Score 2026: Exactly What You Need to Pass, and for a data-grounded look at outcomes across employers, see AON Pass Rate 2026: What the Data Shows.
Mapping Your Prep to the AON Format
Generic study advice doesn't transfer well to a modular, time-pressured battery like this. What does transfer is scheduling practice around the specific modules you're likely to face, especially scales verbal and scales numerical, since their extreme time pressure - where most candidates can't reach even half the items - is the defining difficulty of the whole suite.
Diagnose and Familiarize
- Run a free session on Aon's own practice platform, Aon TestIt
- Time yourself on scales verbal and scales numerical formats specifically
Speed Under Pressure
- Drill scales cls and scales ix with a visible countdown timer
- Practice skipping and returning rather than stalling on hard items
Gamified Modules
- Get comfortable with gridChallenge and switchChallenge mechanics
- Since items regenerate at run time, focus on strategy, not memorized answers
Behavioral and Situational
- Review chatAssess-style situational prompts and ADEPT-15 response patterns
- Simulate a full battery in one sitting to build stamina
Aon publishes free official resources worth using before any paid prep: Aon TestIt plus screencast videos on its "Prepare for your Online Assessment" page. Layer targeted timed practice on top of those, and you'll cover most of what's realistically testable. For a structured walkthrough of this exact approach, see AON Study Guide 2026: How to Pass on Your First Attempt, and for an honest read on difficulty expectations, How Hard Is the AON Exam? Complete Difficulty Guide 2026 is worth reading before you set a study calendar.
You can also run realistic timed drills against many of these formats using the practice sets on our main practice test platform, which mirrors the pacing challenges candidates report most often.
Frequently Asked Questions
Aon Assessment is a division of Aon plc, the same parent company known for insurance and risk services, but the assessment platform itself is a distinct product line built around cut-e's original testing technology.
No. There is no candidate fee. The employer that invites you licenses the assessment directly from Aon, so cost never falls on the applicant.
Each module runs between 2 and 15 minutes, and employers choose which modules to include, so total time varies by employer rather than being fixed across all candidates.
Retake windows are set by the individual employer, not by Aon, so policy varies by company and role rather than following a universal rule.
Cut-e was the Hamburg-based company Aon acquired in May 2017, and its branding still appears in some job adverts and invitation templates even though the tests are identical to current Aon Assessment modules.
