Diagrammatic Reasoning Tests

Diagrammatic reasoning tests assess your logical reasoning ability. The questions measure your ability to infer a set of rules from a flowchart or sequence of diagrams and then to apply those rules to a new situation.

Diagrammatic Reasoning Tests

What are diagrammatic reasoning tests?

Diagrammatic tests use shapes, patterns and figures, rather than numbers and words. They are used by recruiters to assess your ability to think logically and solve complex problems.

What skills does diagrammatic reasoning test?

Diagrammatic reasoning assesses both the strength of your inductive reasoning and your deductive capacity. It can be summed up by referring to these two distinctive categories.

These tests will check if you can draw conclusions from the premises, and how quickly it will take you to do so.

Your task is to deduce the underlying logic of a pattern and guess what is next to follow.

What is the diagrammatic test format?

You will be presented with multiple options, and have to choose which one fits. To do this, you’ll need to view the shapes to find rules which can be applied across the sequence.

As this is the type of activity you’ll rarely come across in day-to-day life, it’s important to practice beforehand to familiarise yourself with the types of questions you’ll face.

Like with other psychometric tests, you’ll typically have about one minute per question.

How are diagrammatic reasoning tests different to logical reasoning tests?

There’s normally very little difference between diagrammatic reasoning and logical reasoning tests. Often they’re the same thing, but have different names. The only difference is that sometimes logical reasoning tests won’t involve diagrams.

While diagrammatic reasoning tests will always involve diagrams, occasionally logical reasoning tests will take other forms.

Occasionally, logical reasoning tests will test a candidate’s logic using forms other than diagrams such as verbal questions that require logic to complete.

What is the difference between inductive and deductive reasoning?

Inductive reasoning is gathering pieces of information to form general conclusion. When applied to psychometric tests, it is when a candidate is able to extract data from multiple sources of provided information and then combine it to form a conclusion that would allow for answering a question.

Deductive reasoning is exactly the opposite of inductive reasoning and is known as “top – down logic”. Deduction means applying general rules to solve specific problems. A candidate that has a good deductive reasoning will be able to use a general rule or a knowledge to answer a specific question.

Diagrammatic reasoning example questions

Q) Identify the similarities in the given shapes and determine which example shape also corresponds


Answer: C The number of arches inside the shape corresponds to the number of points of the shape

Q) Making sure to follow the given rules, what will the new combination of shapes look like?


Answer Make sure to apply the rules to the sequence in the order they are presented.

Diagrammatic reasoning test tips

1One question = one minute rule

Make sure you understand how many questions you will have to answer and how long you have to complete the test. Usually, diagrammatic reasoning tests consist of 10 to 15 questions and don’t last longer than 15 - 20 minutes.

2Watch your timing

Don’t let one question to stop. Work out roughly how much time you have per question before you start each test. If it feels like going through hell, keep going!

3Practice in exam conditions

When you practice for your assessment, try to do so in the same conditions in which you will be sitting your real diagrammatic reasoning test. Try a quiet surrounding with a minimal distraction at a table. This will not only keep you more focused but also make silence less daunting while sitting your real assessment.

4Remember to research

Try to find out as much as possible about the assessment’s format the employer is going to tests you with. Employers typically provide that information to candidates on their careers websites.

5Answer the question

It might be obvious but the fact that we mention it means it is not. At least not always. Although there is only one correct answer, the questions will try to trick you. Stay calm and focused and be careful with identifying the patterns. Some of them might look suspiciously similar.

6Be competitive

Try to measure your achievements against other users in order to make sure you stand out in a crowd. The average results might help you to pass to next stage, but might not be enough to bag you that job. Practice makes perfect, particularly with diagrammatic reasoning tests which take some getting used to.
