Diagrammatic Reasoning Tests

What you get with our diagrammatic reasoning practice tests

When you practise through Practice Aptitude Tests, you get access to diagrammatic reasoning assessments designed to reflect the tests used by employers and publishers in real recruitment processes.

• Realistic diagrammatic reasoning questions across 30 tests and 300 questions, covering operators, input/output diagrams and comparing sets questions
• Multiple-choice questions reflecting the structure commonly used in employer assessments from publishers including Cubiks, Saville, SHL and Kenexa
• Timed test simulations to replicate real assessment conditions, including the time pressure of approximately one minute per question
• Worked answer explanations so you can understand the operator rules and logical processes behind each solution
• Performance feedback and score breakdowns to track strengths and weaknesses across different question formats
• Guidance on what to expect in diagrammatic reasoning tests, including typical formats, time limits and how rules are identified and applied to new sequences
• Unlimited practice so you can master the operator types and pattern logic that appear most frequently in employer assessments
• Immediate access to diagrammatic reasoning tests, with the option to cancel at any time

The importance of a diagrammatic reasoning test

Diagrammatic reasoning tests assess logical thinking through visual sequences. The test does not require maths, language skills, or prior knowledge of any subject; it measures pure reasoning ability. Put differently, it demonstrates a candidate’s ability to identify rules, spot patterns, and apply logical thinking, which is of great value to employers.

While diagrammatic reasoning does not require any prior knowledge, preparation and familiarity with the test content and format will help you to achieve a better score. Familiarity with the question formats makes a measurable difference to scores.

The format of a diagrammatic analysis aptitude test

• Multiple-choice, typically 30 questions
• Time limit of around 25 to 30 minutes, roughly one minute per question
• Questions increase in difficulty as the test progresses
• Some publishers time each question individually; others give a single window for the full test
• Format is consistent across industries and roles, no subject-specific content, but might vary based on the test publisher

Unlock your full potential with diagrammatic reasoning practice

Employers such as Deloitte, KPMG, the Civil Service, Amazon and the NHS use diagrammatic reasoning tests to screen candidates at scale. A strong score moves you through to the next stage, while a weak one ends the process before an interviewer has even seen your CV.

These tests appeal to recruiters because they measure reasoning ability independent of degree subject, work experience or communication style. Two candidates with identical CVs can score very differently, which makes the test a reliable differentiator at high volume.

For you, that means preparation is one of the few variables you can actually control. Practising with realistic questions under timed conditions raises both your accuracy and your speed. That translates directly into a higher score.

Common diagrammatic test publishers

Diagrammatic reasoning tests vary by provider, with differences in question format, difficulty, and timing. These tests typically assess logical thinking, pattern recognition, and rule application using visual sequences.

The most used test providers include:

• Cubiks: Known for its Reasoning for Business (RfB) series, Cubiks offers one of the most widely used diagrammatic reasoning tests. It includes 60 questions to be completed in 30 minutes, measuring how well candidates interpret and draw logical conclusions from visual data.

• Saville Assessment: Offers both standalone diagrammatic reasoning tests and a shorter version within its Swift series. The full test includes 32 questions to be completed in 24 minutes, focusing on rule-based logic and abstract patterns.

• SHL: Provides diagrammatic reasoning assessments that evaluate a candidate’s ability to understand complex systems and identify logical sequences. These are often used for technical and analytical roles.
