Cognitive ability tests — often referred to as intelligence tests in everyday language — are one of the most widely used tools in professional assessment processes. But there is considerable variety in the specific tests available. Here is an overview of the most common types and instruments you are likely to encounter.
Intelligence tests in a professional context typically measure general cognitive ability, sometimes broken down into specific components such as verbal reasoning, numerical reasoning, abstract reasoning, and spatial ability. The underlying construct — general mental ability or "g" — is one of the strongest known predictors of job performance across a wide range of roles.
Logiks is one of the most widely used cognitive ability tests in professional selection. It is available in two versions: Logiks General (a shorter, adaptive version) and Logiks Advanced (for graduate and professional-level roles). It measures verbal, numerical, and abstract reasoning.
Bright is a validated cognitive ability test available through the Selection Lab platform. It measures general reasoning ability and is designed to be both psychometrically rigorous and accessible for candidates.
The Watson-Glaser is specifically designed to measure critical thinking — the ability to analyse information, evaluate arguments, and draw sound conclusions. It is particularly popular in legal and financial services recruitment.
The SHL Verify range includes a variety of cognitive tests covering verbal reasoning, numerical reasoning, inductive reasoning, and deductive reasoning. They are widely used across industries and levels.
Raven's matrices are one of the most widely researched cognitive assessments in existence, measuring non-verbal abstract reasoning. They are designed to minimise the influence of language and educational background, making them particularly useful in diverse or multilingual candidate pools.
Increasingly, cognitive ability is being assessed through game-based formats. Tools like Aivy and UCognify measure cognitive traits through interactive mini-games, offering a more engaging candidate experience while maintaining scientific validity. These are available through the Selection Lab platform.
The choice of cognitive ability test should be guided by the demands of the role, the candidate population, and the level of scientific evidence available for the instrument. Want to know which cognitive tests Selection Lab recommends for your specific context? Get in touch with us.
