- Aon Assessment is published by Aon Assessment Solutions, formerly the cut-e brand acquired in 2017.
- There's no candidate fee - the hiring employer licenses the assessment, not the applicant.
- Aon delivers roughly 30 million assessments a year in 40+ languages across 90 countries.
- Scoring is percentile-based against norm groups; there is no universal passing score.
What Is Aon Assessment?
"AON" on this site refers specifically to Aon Assessment, the pre-hire testing platform published by Aon Assessment Solutions. This is the business Aon plc built after acquiring the Hamburg-based testing company cut-e in May 2017. If you've received an invitation email or job advert referencing "cut-e," that's not a different product - it's the same tests under a legacy name that still circulates in employer communications.
Aon Assessment is not a professional certification you study for independently and schedule at a testing center. It's an employer-driven evaluation tool: companies license the platform and invite candidates to complete specific modules as part of a hiring pipeline. There is no Pearson VUE, PSI, or Prometric involvement, and critically, no candidate fee - the employer pays for access, not you.

Who Uses Aon Assessment and Why
Employers turn to Aon Assessment when they need to screen high volumes of applicants quickly and consistently - most visibly in graduate recruitment programs and financial-services hiring, where the scales verbal and scales numerical modules see the heaviest use. These two modules are typically the first hurdle candidates face, and their aggressive time limits are widely cited as the defining difficulty of the entire suite.
Because the battery is modular, no two employers necessarily test the same combination. A finance graduate scheme might pair scales numerical with ADEPT-15, while an operations role might lean on gridChallenge or motionChallenge to assess working memory and planning. Understanding which employer type tends to favor which module combination is part of preparing intelligently - a topic covered in depth in AON Exam Domains 2026: Complete Guide to All 12 Content Areas.
How Registration and Delivery Actually Work
There's no self-registration portal to browse and book a slot. Access begins with an employer invitation, typically sent by email, that opens a testing window - usually five to ten days - during which the candidate must log in and complete the assigned modules on Aon's own browser-based platform. Missing that window generally means missing the opportunity, since retake and rescheduling policies are set entirely by the employer, not by Aon itself.
This structure changes how you should think about "exam dates." There's no fixed annual calendar the way there is for many professional certifications - each invitation window is unique to the employer and the specific requisition. If you're trying to understand how testing windows are typically structured and what to do if a window is tight, AON Exam Dates 2026: Testing Windows, Deadlines & Scheduling walks through the mechanics in more detail.
Because there's no candidate fee, cost-related questions usually center on prep resources rather than exam pricing. If you're weighing whether to invest in structured practice, AON Certification Cost 2026: Complete Pricing Breakdown and Is the AON Certification Worth It? Complete ROI Analysis 2026 break down what actually costs money in this process versus what's free.
Key Takeaway
Register nothing yourself - wait for the employer's invitation email, note the window length immediately, and treat the five-to-ten-day timer as a hard deadline with no guaranteed extension.
Inside the Module Battery
Aon assembles test batteries from three families: the scales ability tests, the smartPredict gamified challenges, and behavioral instruments like ADEPT-15 and chatAssess. Each module has a fixed or adaptive format, and the published specifications matter a lot for pacing strategy.
Domain 1: scales verbal
47 questions in 12 minutes. Verbal reasoning under Aon's platform is less about vocabulary and more about rapid true/false/cannot-say judgments against short passages.
- Speed matters more than depth of analysis on any single item
Domain 2: scales numerical
37 questions in 12 minutes. Numerical reasoning pulls from tables, charts, and short data sets requiring quick estimation.
- Most candidates cannot reach half the items - pacing beats perfectionism
Domain 3-4: scales cls and scales ix
scales cls covers 12 tasks in 12 minutes of inductive-logical reasoning; scales ix covers 20 questions in 5 minutes of inductive reasoning. Both test pattern recognition under compressed time.
Domain 5-6: scales eql and scales lt
scales eql assesses basic numeracy in 5 minutes; scales lt evaluates language skills across a 10-minute window. These modules tend to appear in broader screening batteries rather than as standalone gatekeepers.
Domain 7-10: The smartPredict Challenges
switchChallenge (deductive reasoning), gridChallenge (working memory), motionChallenge (complex planning), and digitChallenge (numeracy) run between 5 and 9 minutes each. Every item in this family is generated at run time, so practice should focus on mechanics, not memorized answers.
Domain 11-12: chatAssess and ADEPT-15
chatAssess (situational judgement) runs 15 minutes; ADEPT-15, an adaptive personality instrument, takes 20 minutes of test time or 23 minutes including instructions. Neither has "correct" answers in the traditional sense - consistency matters more than optimization.
Other timed modules include scales verbal instruct (24 questions, 8 minutes), mechanical reasoning (24 questions, 15 minutes), and scales e3+ (a rapid 2-minute module). A full breakdown of every module's format, timing, and what it's actually measuring is available in AON Exam Domains 2026: Complete Guide to All 12 Content Areas.
| Module | Format | Time |
|---|---|---|
| scales verbal | 47 questions | 12 minutes |
| scales numerical | 37 questions | 12 minutes |
| scales cls | 12 tasks | 12 minutes |
| scales ix | 20 questions | 5 minutes |
| gridChallenge | 9 tasks | 9 minutes |
| ADEPT-15 | Adaptive personality | 20-23 minutes |
| chatAssess | Situational judgement | 15 minutes |
How Scoring and Benchmarks Work
There is no universal passing score in Aon Assessment. Scoring is percentile-based against norm groups - your raw performance is compared to a relevant comparison population, and each employer decides where to set its own benchmark for advancement. This means the same raw score could clear the bar for one employer's graduate scheme and fall short for another's.
Retake policies follow the same logic: the employer sets the rules, not Aon. Some allow a retake after a cooling-off period; others don't allow one at all within the same hiring cycle. If you want a precise breakdown of how percentile scoring translates into practical pass/fail outcomes, AON Passing Score 2026: Exactly What You Need to Pass and AON Pass Rate 2026: What the Data Shows go deeper into what the norm-group model actually means for candidates.
Why No Two Candidates See the Same Test
Several scales modules are adaptive, and every smartPredict item is generated at run time - meaning the specific questions you see are effectively unique to your session. Aon states this is a deliberate method for controlling cheating in unsupervised, at-home administration, where there's no proctor watching the screen.
The practical implication for candidates: memorizing specific answer keys from forums or friends is close to useless. What transfers instead is familiarity with the format - how a scales verbal true/false/cannot-say item is structured, how a gridChallenge memory task escalates, how motionChallenge sequences planning steps. That's exactly the kind of pattern-level preparation Aon's own free resources are built around.
Building a Module-Aware Prep Plan
Because Aon Assessment has no fixed exam date and can arrive with as little as five days' notice, prep needs to be front-loaded rather than scheduled around a distant deadline. Aon runs a free official practice platform called Aon TestIt, plus practice tasks and screencast videos on its Prepare for your Online Assessment page - both worth exhausting before paying for anything else.
General Readiness
- Run through Aon TestIt to learn the interface and item styles
- Drill scales verbal and scales numerical pacing since they're the most commonly assigned modules
- Get comfortable with true/false/cannot-say logic, which trips up untrained candidates
Module-Specific Drilling
- Identify which exact modules the employer assigned from the invitation email
- Practice smartPredict-style tasks (gridChallenge, switchChallenge, motionChallenge) for format familiarity, not memorized answers
- Time yourself strictly - most candidates never reach half the items in scales numerical, so pacing decisions matter more than raw skill
Consolidation and Submission
- Review ADEPT-15 and chatAssess expectations - consistency, not optimization, is the goal
- Complete the assessment with time to spare before the window closes
- Avoid last-minute submissions given no guaranteed technical support buffer

Complete Difficulty Guide 2026. You can also work through timed practice sets on our practice test platform to build the same under-pressure decision-making the real modules demand.
Key Takeaway
Prioritize scales verbal and scales numerical pacing drills over everything else - they're the highest-volume modules and the ones where time pressure, not difficulty, decides most outcomes.
Frequently Asked Questions
No. The hiring employer licenses the assessment, so candidates are never charged a fee to complete an invited test.
Yes. Aon acquired cut-e in May 2017, and the cut-e name still appears in some job adverts and invitation emails, but it refers to the identical tests published under Aon Assessment Solutions.
There isn't a universal passing score. Scoring is percentile-based against norm groups, and each employer sets its own benchmark for what counts as advancing.
Invitation windows typically run five to ten days from the invitation email, though the employer controls the exact window and any flexibility around it.
Retake availability is set by the employer, not by Aon, so policies vary widely between hiring processes and roles.
