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.
