Most organisations consider aptitude as a benchmark for predicting a candidate’s ability to perform a specific role. Pre-employment aptitude tests are highly successful at identifying the candidates who are most likely to succeed in their roles.

Thomas’s Aptitude assessment enables organisations to gain a detailed understanding of a person’s fluid intelligence and how quickly they can grasp the fundamentals of a new role. The assessment focuses on a range of cognitive skills and covers individuals’ abilities to reason, detect errors, process numbers, words, and visual information.

The Thomas Aptitude assessment can provide answers to questions such as:

  • Can they cope with the cognitive demands of a role?

  • What job experience level will this person be suitable for?

  • What pace of work will fit them best?

  • Will this person match the learning requirements of a role?

  • Can they thrive in a role that will evolve and change over time?

The 5 tasks that measure speed of learning


The Articulate component is a semantic word task. A person's vocabulary and understanding of words are measured by asking them to identify two words that have a similar meaning out of a choice of three. This assesses their comprehension of a large number of words from different parts of speech and the ability to process written and verbal information.


The Numerate component is a number task. A person's numerical reasoning is measured by asking them to identify the magnitude of distance between a series of numbers. This assesses their ability to manipulate numerical information, their numerical reasoning and how comfortably they can work with quantitative concepts.


The Deductive component is a problem-solving task. A person's verbal reasoning is measured by asking them to hold verbal information in their short-term memory and make decisions based on that information. This component assesses their ability to make inferences, reason from verbal information and draw correct conclusions.


The Perceptual component is a matching task. A person's perceptual speed was measured by asking them to identify the correct number of matching pairs of letters or characters. This component assesses their ability to check and report for error/accuracy in written material, numbers and diagrams as well as the ability to ignore irrelevant information.


The Conceptual component is a symbol task. A person's spatial and mechanical reasoning is measured by asking them to visualise and manipulate a symbol in their mind. This component assesses their ability to create and manipulate mental images of objects and to understand how shapes and patterns fit together to form a whole.

Reliability & Validity

Thomas' Aptitude assessment has been subject to rigorous scientific testing and proven to be a reliable and valid measure for speed of learning and trainability. It is also registered with the British Psychological Society (BPS) after it was audited against the technical criteria established by the European Standing Committee on Tests and Testing, part of the European Federation of Psychologists' Associations.
