- There is no candidate fee; the hiring employer licenses the battery from Aon Assessment Solutions.
- Invitation windows typically run five to ten days, so checking your inbox promptly is a real requirement.

What "Requirements" Actually Means for Aon Assessment
Search for "AON requirements" and you'll find a mix of unrelated credentials online - this article is exclusively about Aon Assessment, the online testing platform built by Aon plc after its 2017 acquisition of the Hamburg-based firm cut-e. If you've received an email referencing "cut-e," "scales," or "smartPredict," you're looking at the same suite covered here.
Unlike a licensing exam with tuition, prerequisite courses, or a governing board, Aon Assessment has no formal eligibility criteria that candidates set up themselves. You cannot register on your own, pay a fee, or book a slot the way you would for a Pearson VUE or Prometric exam. The single requirement is an employer invitation: a company you've applied to has licensed a specific test battery and sent you a link to complete it, usually as part of an early-stage hiring funnel.
That said, "requirements" in a practical sense still applies - meeting deadlines, having the right equipment, and being familiar with the module formats described in our AON Exam Domains 2026: Complete Guide to All 12 Content Areas are all things you control and should prepare for.
Who Invites You: Employers and Roles
Aon reports administering roughly 30 million assessments a year across more than 40 languages and 90 countries, which means the invitations come from a huge range of employers rather than one industry. In practice, the heaviest volume sits in graduate schemes and financial-services recruiting, where scales verbal and scales numerical are used constantly to screen large applicant pools quickly.
If you're wondering whether a specific job posting will route through Aon, check whether the recruiter mentions "online assessment," "cut-e," or a gamified test - these are strong signals. Our AON Jobs overview breaks down the sectors and role types most likely to use this battery, and What Is AON? covers the platform's background if you want the full context before your invite arrives.
Key Takeaway
You don't apply to "take Aon Assessment" directly - you apply to a job, and the employer's hiring process determines whether Aon modules appear in your funnel.
Technical Prerequisites You Must Meet
Because Aon administers everything through its own browser-based platform - with no Pearson VUE, PSI, or Prometric involvement - the "requirements" that matter most on test day are technical, not academic:
- A stable internet connection capable of holding a video/interactive session without dropping for the full module duration.
- An up-to-date browser compatible with the invitation link (check the email for any stated browser guidance).
- A quiet, uninterrupted block of time matching or exceeding the module's stated length - some modules run as short as 2 minutes, others up to 20 or 23 minutes including instructions.
- Completion within the invitation window, which typically runs five to ten days from the email being sent.

The Three Module Families You'll Face
Employers don't administer one fixed "exam" - they assemble a custom battery pulled from three families. Knowing which family you're being tested on is itself a kind of readiness requirement, because each family demands a different skill set.
1. scales Ability Tests
Traditional timed reasoning tests measuring verbal, numerical, logical, and language skills. These are the modules with the strictest time pressure.
- scales verbal - 47 questions in 12 minutes
- scales numerical - 37 questions in 12 minutes
- scales cls, scales ix, scales eql, scales lt, scales verbal instruct
2. smartPredict Gamified Challenges
Interactive, often visual tasks measuring working memory, planning, and deductive reasoning. Every item is generated at run time, so no two candidates see the same test.
- gridChallenge, switchChallenge, motionChallenge, digitChallenge, clx
3. Behavioral Instruments
Personality and situational-judgment tools that don't have "correct" answers in the traditional sense but still require honest, consistent self-presentation.
- chatAssess (situational judgement, 15 minutes)
- ADEPT-15 (Adaptive Employee Personality Test, 20 minutes of test time, 23 with instructions)
For a module-by-module walkthrough, our companion piece AON Exam Domains 2026: Complete Guide to All 12 Content Areas covers each of the twelve areas in depth.
Domain-by-Domain Qualification Checklist
Because the requirement to "pass" is really a requirement to perform well enough against an employer's chosen benchmark, treat each domain below as a separate readiness target rather than one monolithic exam.
| Domain | What It Measures | Format Note |
|---|---|---|
| scales verbal | Verbal reasoning | 47 questions, 12 minutes |
| scales numerical | Numerical reasoning | 37 questions, 12 minutes |
| scales cls | Inductive-logical reasoning | 12 tasks, 12 minutes |
| scales ix | Inductive reasoning | 20 questions, 5 minutes |
| scales eql | Basic numeracy | 5 minutes |
| scales lt | Language skills | 10 minutes |
| switchChallenge | Deductive reasoning | 6 minutes, adaptive/generated |
| gridChallenge | Working memory | 9 tasks, 9 minutes |
| motionChallenge | Complex planning | 6 minutes |
| digitChallenge | Numeracy | 5 minutes |
| chatAssess | Situational judgement | 15 minutes |
| ADEPT-15 | Adaptive personality profile | 20 minutes (23 with instructions) |
Registration, Invitation Windows, and Fees
Because Aon Assessment isn't a certification you buy, several "requirements" that apply to traditional exams simply don't exist here:
- No candidate fee - the hiring employer licenses the assessment from Aon Assessment Solutions, so you never pay to test.
- No independent scheduling - you cannot book a session yourself; the invitation email is the only entry point.
- No third-party test center - everything runs on Aon's own browser-based platform.
- Employer-set retake rules - if you're allowed a second attempt, the retake window and eligibility are decided by the employer, not by Aon.

How You "Qualify": Scoring Without a Universal Pass Mark
Perhaps the most misunderstood requirement is what it takes to "pass." Aon Assessment doesn't publish a universal cutoff score. Instead, scoring is percentile-based against relevant norm groups, and each employer sets its own benchmark for what counts as a qualifying result on a given module or combination of modules.
Key Takeaway
There is no fixed passing score to memorize. Your "requirement" is to perform well relative to a norm group, and the bar itself shifts by employer and role - read AON Passing Score 2026: Exactly What You Need to Pass for the full explanation.
This also means comparing your result to a friend's or a forum post's experience is largely meaningless - different employers, different roles, different norm groups. For a data-grounded look at how outcomes vary, see AON Pass Rate 2026: What the Data Shows.
Meeting the Requirements: A Preparation Timeline
Since the real "requirement" is performance under time pressure across a battery you may not fully control, structuring a short preparation sprint around the specific modules named in your invitation email is the most efficient path forward.
Identify Your Battery
- Re-read the invitation email for named modules (e.g., scales numerical, gridChallenge)
- Confirm your device and browser meet the technical prerequisites
Drill the Timed scales Modules
- Practice scales verbal and scales numerical under strict 12-minute limits
- Focus on speed-of-elimination, since most candidates can't finish every item
Adapt to smartPredict Formats
- Use Aon TestIt and the practice tasks on Aon's Prepare for your Online Assessment page to see gamified item styles
- Since every smartPredict item is generated at run time, prioritize understanding rules over memorizing answers
Behavioral Consistency Check
- Review chatAssess situational scenarios and ADEPT-15's personality framing
- Rest and confirm your quiet, uninterrupted test window before the invitation expires

Frequently Asked Questions
No. Aon Assessment itself has no academic prerequisite. Any eligibility criteria (degree, experience level) come from the employer's job posting, not from Aon.
No. There is no self-registration or public booking system. The only way to take the modules is through an employer-issued invitation link.
No. The hiring employer licenses the assessment from Aon Assessment Solutions, so candidates are never charged a fee.
Invitation windows typically run five to ten days. Missing that window generally means missing your chance to complete the assessment for that application, since Aon does not run its own separate scheduling system.
No. Cut-e is the original company name that Aon acquired in 2017; the name still appears in some invitation emails but refers to the identical Aon Assessment modules described here.
