What is a passing score on the Aon online assessment tests?

As the Aon tests are used by a wide variety of employers across different sectors, each employer has their own benchmark that candidates must attain to be successful in the tests. Depending on the role and employer, the score will also differ depending on the level of proficiency required for the position.

Which professions use Aon tests, and why?

Aon’s tests are used in the recruitment process for professions such as those in financial services and IT, where strong numerical reasoning and an aptitude for analytical reasoning are essential for the role.

Many roles in accountancy and consulting also require individuals to be able to read, analyze and make logical inferences from various data sources. As logical, numerical, and verbal reasoning are central to success in these types of roles, employers use the results of the Aon tests to gain an objective view of an individual’s abilities.

How to prepare for an Aon test

The key to performing to the best of your ability in an Aon test is to practice the tests.

While the abilities being assessed in an Aon test are inherent, practicing the tests ensures you become familiar with the format, style of questions, and how you react under the time pressure you will feel when taking the test itself.

When preparing for the test, simulate the test environment. Make sure you practice tests under timed conditions. Ensure you take your practice test in a quiet room, free from distractions.

Sharpen your logical reasoning skills by practicing puzzles such as sudoku. This helps train your mind to spot relationships or links between abstract information.

When practicing for the numerical assessments, refresh your memory on basic mathematical principles such as fractions and equations.

Aon Tips

1Know What's Coming

An Aon test is like a road trip – knowing the route in advance helps you navigate it better. Familiarize yourself with the kind of assessments you’ll face, ranging from numerical and verbal reasoning to personality tests. At Practice Aptitude Tests, we offer a broad spectrum of simulations that mirror the core abilities Aon’s assessments measure. Understanding the structure and types of questions beforehand can significantly boost your performance.

2Create a Study Plan

Succeeding in Aon tests doesn’t come by chance; it’s all about a solid game plan. Break down your prep time into dedicated slots for each type of assessment you’ll encounter. Regular, focused practice is more effective than a last-minute cram session. Just like a workout routine, consistency in preparing can strengthen your aptitude muscles!

3Simulate Test Conditions

Ever noticed how a dish tastes different at home compared to a restaurant? Context matters! It’s the same with Aon tests. Recreating exam conditions can make a huge difference. Use Practice Aptitude Tests to take timed tests in a quiet environment. The more you practice under test-like constraints, the more comfortable you’ll become on the big day.

4Reflect on Your Practice

After each practice session at Practice Aptitude Tests, take a moment to reflect. Which questions were tricky? Did you stumble on data interpretation, or was it the time pressure? Identifying weak spots allows you to be strategic in your subsequent practice, turning potential stumbling blocks into stepping stones for success.

5Care for Your Well-Being

Here’s a secret – your mind performs best when your body is taken care of. Ensure you’re well-rested, hydrated, and nourished on the days leading to your Aon test. A calm mind can conquer complex problems more efficiently, so don’t underestimate the power of a good night’s sleep and a balanced meal before you dive into those assessments.
