- Aon Assessment has no fixed annual exam dates - employers send individual invitations with a testing window.
- Invitation windows typically run five to ten days from the moment the employer sends the link.
- There is no candidate fee because the hiring employer licenses the assessment, not the applicant.
- Retake windows are set entirely by the employer, not by Aon, so timelines vary by job posting.
Why There's No Fixed "AON Exam Date" in 2026
If you searched for "AON exam dates 2026" expecting a published calendar of testing days, here's the first thing to unlearn: Aon Assessment doesn't work that way. There is no January sitting, no quarterly window, no registration portal where you pick a date months in advance. Aon Assessment Solutions - the entity Aon plc built after acquiring Hamburg-based cut-e in 2017 - administers its tests directly through its own browser-based platform, entirely on employer invitation. You'll still see the "cut-e" name in some job adverts and invite emails; that's the same assessment, just an older brand reference that never fully disappeared.
Because there's no Pearson VUE, PSI, or Prometric booking system involved, there's also no candidate fee and no calendar to browse. The employer you're applying to licenses the assessment from Aon and controls when it's sent, how long you have to complete it, and when (or if) you can retake it. Your "exam date" is really a window that opens the moment a recruiter clicks send.
Understanding Invitation Windows
Once you apply to a role that uses Aon's tools, you'll typically receive an email containing a unique link to the testing platform. That email will state a deadline - Aon's invitation windows typically run five to ten days from the send date. This isn't a universal rule enforced by Aon itself; it's a default range employers configure, and some organizations shorten or extend it depending on hiring urgency.
What this means practically:
- The clock starts on send, not on open. If you don't check your inbox for three days, you've already lost three days of your window.
- There's no rescheduling button. Unlike a proctored center booking, you generally can't push your own window back - you'd need to contact the recruiter or hiring team directly.
- Weekends count. A five-day window sent on a Thursday afternoon can effectively become a single working day if you're not paying attention.
Because the invitation window is the entire "exam date" concept for AON, treating that email as time-sensitive matters more than it would for a traditional certification exam booked weeks in advance.
Key Takeaway
Open the invitation email immediately, note the exact deadline (date and time zone if given), and block a distraction-free session well before the last day - don't save it for the final hours of the window.
Who Sends the Invite - and When
Aon's assessments are used heavily in graduate recruitment and financial-services hiring, among other sectors, which is why scales verbal and scales numerical carry the heaviest volume across those pipelines. Employers typically send the invitation after an initial application or CV screen, before interviews. That sequencing matters for scheduling: you often get very little advance notice that a test is coming, because it's triggered by an applicant-tracking system the moment your application clears the first filter.
This is different from certifications where you register for an exam date yourself. With AON, the "registration" event and the "testing window" arrive together, in the same email, from the employer's recruiting team. If you're actively applying to multiple employers that use Aon's battery, you should expect these invitations at unpredictable intervals - sometimes days after applying, sometimes weeks.
Module-by-Module Timing You'll Actually Face
Once you open the link, the "exam" itself is a modular battery - not one long test. Employers assemble a battery from three families: the scales ability tests, the gamified smartPredict challenges, and behavioral instruments. Each module is short, and total sitting time is usually well under an hour depending on what the employer selected.
scales verbal
47 questions in 12 minutes. Extreme time pressure is the defining difficulty here - most candidates cannot reach half the items, so pacing strategy matters more than raw vocabulary knowledge.
- Skim-and-eliminate approach beats careful reading of every option
scales numerical
37 questions in 12 minutes, drawing on tables, charts, and ratios rather than pure arithmetic recall.
- Practice reading data under a ticking clock, not just solving problems untimed
scales cls and scales ix
Inductive-logical and inductive reasoning tasks - 12 tasks in 12 minutes for cls, 20 questions in 5 minutes for ix. Pattern recognition speed is the bottleneck.
smartPredict challenges
gridChallenge (9 tasks, 9 minutes, working memory), switchChallenge, motionChallenge and clx (6 minutes each), digitChallenge (5 minutes) - these are gamified and, critically, generated at run time so no two candidates see an identical version.
Other modules you may encounter include scales lt (10 minutes), scales verbal instruct (24 questions, 8 minutes), mechanical reasoning (24 questions, 15 minutes), scales eql (5 minutes), scales e3+ (2 minutes), chatAssess (15 minutes, situational judgement), and ADEPT-15 (20 minutes of test time, 23 minutes including instructions, the adaptive personality instrument). For a full breakdown of what each one measures, see the AON Exam Domains 2026: Complete Guide to All 12 Content Areas.
Scheduling Your Own Prep Around the Window
Because you don't control when the invitation lands, your prep needs to happen before you apply, not after. A useful way to think about this: treat the days between submitting an application and receiving the invite as your real study period, since once the email arrives your window for finishing the test is measured in days, not weeks.
Baseline familiarity
- Run through Aon TestIt, Aon's free official practice platform
- Skim the screencast videos on Aon's Prepare for your Online Assessment page
Domain-specific drilling
- Time yourself on verbal and numerical items to build pacing instincts
- Review the full domain list in the AON Exam Domains 2026 guide
Execute within the window
- Pick a quiet, uninterrupted block early in the five-to-ten-day window
- Confirm device, browser, and connection before starting the timed modules
For a structured approach to the prep phase itself, the AON Study Guide 2026: How to Pass on Your First Attempt walks through pacing drills and module-specific tactics in more depth, and our practice test platform lets you rehearse the timed format before the real invitation arrives.
Retake Windows and Deadlines
There is no universal pass mark on AON modules - scoring is percentile-based against norm groups, and each employer sets its own benchmark. That also means retake windows are set by the employer rather than by Aon. Some employers allow a second attempt after a cooling-off period; others treat the first submission as final for that hiring cycle. Because Aon itself doesn't publish a standard retake calendar, you should assume no retake is guaranteed unless the recruiter explicitly says otherwise.
If you're unsure why scoring works this way, or what "passing" even means on a percentile system, the AON Passing Score 2026: Exactly What You Need to Pass article breaks down how norm groups and benchmarks function, and AON Pass Rate 2026: What the Data Shows covers what's publicly known about outcomes.
What Happens If You Miss the Deadline
Missing the window is generally treated the same as withdrawing from the process - the link expires, and in most cases the application moves no further without direct contact with the recruiter. Because there's no central Aon scheduling desk you can call to extend a candidate window (the relationship is between Aon and the employer, not Aon and you), your only real recourse is emailing the hiring contact listed in the invitation and asking, politely and promptly, whether an extension is possible.
- Reply to the invitation email as soon as you realize you'll miss the deadline - don't wait until it has already passed.
- Reference the specific role and application ID if one was provided.
- Ask directly whether a new link can be issued; some employers can regenerate one, others cannot.
How AON Scheduling Compares to Traditional Test Centers
It helps to see the contrast side by side, especially if you're used to certification exams that involve booking a seat weeks ahead.
| Feature | Traditional Proctored Exam | Aon Assessment (AON) |
|---|---|---|
| Who schedules it | Candidate books a date/time | Employer sends an invitation link |
| Testing location | Test center or proctored remote session | Aon's own browser-based platform, unsupervised |
| Candidate fee | Paid by candidate | None - employer licenses the assessment |
| Booking window | Weeks to months in advance | Invitation window, typically 5-10 days |
| Retakes | Set policy with published cooling-off period | Determined by individual employer |
| Question uniqueness | Fixed item banks | smartPredict items generated at run time - no two candidates see the same test |
That last row matters for anyone comparing AON to other assessments: because Aon generates smartPredict items on the fly, this is Aon's own stated method for controlling cheating in unsupervised, unproctored administration. It also means practicing on generic "question dumps" is far less useful than building genuine speed and reasoning fluency, which is exactly what modules like How Hard Is the AON Exam? Complete Difficulty Guide 2026 addresses in detail.
Key Takeaway
Since the questions themselves change per candidate, spend your limited prep time on pacing and reasoning patterns rather than trying to memorize specific answers.

Frequently Asked Questions
No. Aon Assessment has no public sitting dates. Testing happens on employer invitation, with a window - typically five to ten days - starting when the recruiter sends your link.
Not directly. The invitation window is set by the employer, not by Aon or the candidate. If you need more time, you must contact the recruiter listed in your invitation email.
No. There is no candidate fee because the hiring employer licenses the assessment directly from Aon Assessment Solutions.
The overall window is typically five to ten days, but once you start the actual modules, most batteries are completed in a single sitting since each module runs only 2 to 15 minutes.
There's no fixed retake schedule from Aon - retake windows and eligibility are decided by each individual employer, so timelines vary widely by company and role.
