Aon Assessments

What is an Aon test?

An Aon test is an assessment many employers use as part of the early stages of the recruitment process. Aon offers several tests, each evaluating individuals on a different skill or ability, meaning that employers may use multiple tests as part of their recruitment process for a role.

Aon tests can be divided into three different categories:

• Performance tests
• Skills tests
• Personality tests

Which cover the following tests:

• Verbal reasoning (scales verbal)
• Numerical reasoning (scales numerical)
• Language skills (scales lt)
• Mechanical reasoning (scales mtu)
• Understanding of basic instructions (scales verbal instruct)
• Basic numerical comprehension (scales eql)
• Complex planning capability (motion challenge)
• Working memory (grid challenge)
• Ability to concentrate (scales e3+)
• Numeracy (digit challenge)
• Situational judgment test (chatassess)
• Inductive logical reasoning assessment (scales cls)
• Inductive reasoning (scales ix)
• Inductive reasoning (clx)
• Deductive reasoning (switch challenge)
• Deductive logical thinking (scales first)

What is the format of an Aon test?

The Aon aptitude tests are online timed assessments, each assessment evaluating a specific aptitude.

At the start of an Aon test, candidates are shown a short introductory video outlining the instructions for completing the test and the designated time limit. They are then asked to complete some short questions to ensure they have understood the instructions and how to answer the questions in the test.

Below are the different types of Aon tests and how each of these tests is formatted.

Verbal reasoning (scales verbal)

The Aon verbal reasoning assessment, also known as the scales verbal test, assesses an individual’s aptitude in understanding information and making logical conclusions. The test consists of 47 questions with a time limit of 12 minutes for completion. Questions are presented as small pieces of information shown on different tabs. They need to move back and forth between the tabs, analyze the data and select which of the multiple-choice answers is correct.

Numerical reasoning (scales numerical)

The numerical reasoning assessment comprises 37 questions with 12 mins to complete and evaluates a candidate’s ability to analyze and understand numerical data. Information is presented on different tabs as tables, graphs, or charts. Candidates are given a statement in relation to the information, then must select whether the statement is false, true, or they can not say based on all the information given.

Language skills (scales lt)

Also known as the scales lt test and lasting 10 minutes, the Aon language skills test evaluates candidates’ proficiency in using the English language.

The test is multiple-choice, comprising three different tasks. One focused on spelling, one where individuals select which multiple-choice word describes the definition provided, and one where individuals complete a sentence by determining which of the given words is the most appropriate.

Mechanical reasoning (scales mtu)

The mechanical reasoning test assesses individuals’ knowledge of mechanical principles such as gears, levers, and pulleys. The test comprises 24 questions with a time limit of 15 minutes.

Candidates are given questions presented as graphics and a list of multiple-choice answers. They must select which responses are correct based on the information provided.

Understanding of basic instructions (scales verbal instruct)

In this assessment, candidates are required to analyze information and make logical conclusions is evaluated. Questions are given as short paragraphs of information. They must read, analyze and use their understanding of what they have read to determine whether the statement that follows is true or false.

There are 24 questions to complete in eight minutes.

Basic numerical comprehension (scales eql)

The numerical comprehension test assesses an individual’s ability to use mathematical concepts to solve numerical problems. With five questions to complete as many questions in the test, candidates use mental arithmetic to answer each task.

Questions are given as equations, with gaps in each equation. Candidates select which of the multiple-choice numbers should be used to fill the gap in the equation.

Complex planning capability (motion challenge)

Also known as the motion challenge, in this assessment, candidates must complete as many tasks as possible within the six-minute time limit. Questions are presented in the form of grid puzzles along with a shape. Candidates must move the shape horizontally or vertically while considering barriers in the grid to reach an exit point.

Working memory (grid challenge)

This test comprises nine questions at different levels to be completed in nine minutes. Candidates are given a sequence and pattern of nine dots that they must remember while completing another task. Tasks can include mirror image tasks or grids that have been inverted. Upon completion of each task, candidates are asked to choose the order and pattern of the dots shown before the task.

Ability to concentrate (scales e3+)

Also known as the scales 3+ test, this assesses an individual’s capacity to concentrate and take appropriate action. Lasting two minutes, the test takes the form of questions given as the letter ‘E’ and a set number of dots. Candidates must select whether each question contains the letter ‘E’ and three dots answering ‘correct’ or ‘incorrect’ as appropriate.

Numeracy (digit challenge)

This assessment lasts five minutes and evaluates an individual’s mental numerical comprehension. Questions are given as equations with varying levels of difficulty. Candidates select which of the 1-9 numbers correctly fills in the gap in the equation, completing as many questions as they can correctly in the given time limit.

Situational judgment test (chatassess)

Situational judgement assessments take the form of a 15-minute questionnaire. Questions are presented as scenarios they are likely to encounter in the workplace. Candidates are shown an inbox with a list of messages to respond to. They must reply to all messages they receive by selecting their preferred response from the list given or typing in their preferred answer.

Inductive logical reasoning assessment (scales cls)

Candidates must complete as many of the 12 questions as possible in 12 minutes. Questions are presented as grid images along with a color. They must determine the rule that links tables and colors together, then, using this rule, allocate the images to the correct category.

Inductive reasoning (scales ix)

In this assessment, candidates must use their inductive reasoning ability to decide on the link between patterns of information, then select which of the images in the series given does not belong based on the rule identified. Candidates must complete as many of the 20 questions as possible within five minutes.

Inductive reasoning (clx)

This assessment evaluates an individual’s ability to look at patterns, determine relationships and draw logical conclusions. Questions are presented as a series of two grids, including objects. Candidates must identify the rule governing these two grids and then select which two of the four given follows the rule identified. Candidates must complete as many questions as possible in the six minutes allotted.

Deductive reasoning (switch challenge)

This six-minute test presents questions as input and output shapes and various four-digit sequence numbers known as operators. Candidates must determine which operators are correct in achieving the right series of output shapes. With various levels in the test, candidates are expected to complete as many questions in the given time limit.

Deductive logical thinking (scales first)

In this six-minute assessment, individuals use their deductive logic to determine the relationships between shapes shown in a grid. The grid shows a series of four types of shapes with question marks located in different areas in the grid. They must select which object replaces the question mark based on the relationship or link identified.
