The General Intelligence Assessment (GIA)

Aptitude has been widely acknowledged as the most important predictor of job success. The General Intelligence Assessment (GIA) is a cognitive ability assessment that can help to predict how quickly an individual will take to get to grips with a new role or regime.

Why use the General Intelligence Assessment (GIA)?

Measuring the aptitudes of a candidate helps you to understand if that individual will be able to quickly grasp the requirements of the role. It can give you an insight into whether they have the capacity to adapt to new challenges, and if they would be suited to drive change through your organisation.

This insight makes it easier to select the right candidate for the role by placing an objective filter on their ability, regardless of their IQ score, qualifications, and past experience. That’s not to say that IQ, qualifications and experience are unimportant, but they’re not the best predictor of potential performance in a role.

It’s widely acknowledged that not everyone excels at school, and that results from standard national exams or industry-accepted tests aren’t the best way to understand an individual’s capabilities, the level of challenge they need to keep them stimulated and committed, or whether they will respond well to development activities.

Research by the American Psychology Association inc. Frank L. Schmidt & John E. Hunter (1998) reviewed 85 years of research and found that higher cognitive ability, or aptitude as it is also called, as measured by the Thomas Aptitude assessment, is directly linked to higher employee productivity and performance in role.

How the General Intelligence Assessment (GIA) works

The General Intelligence Assessment (GIA) measures an individual's aptitude in 5 key areas: Reasoning, Perceptual Speed, Number Speed & Accuracy, Word Meaning and Spatial Visualisation

5 Online Assessments

The Thomas GIA test consists of 5 online assessments, including reasoning, perceptual speed, number speed and accuracy, word meaning and spatial visualisation.

Detailed Understanding

Gain a detailed understanding of a person’s mental capacity and how quickly they can grasp a new role/regime with the Thomas International GIA test.

Understand General Intelligence

The overall percentile is an estimate of a candidate's general intelligence, while focusing on their response to training, mental processing speed, concentration and fast track potential.

Background & Theory

The GIA, also known as the Thomas Aptitude assessment, was first developed as a way to measure conscious intellectual abilities and trainability of Armed Forces known as the British Army Recruitment Battery (BARB). It was then developed by Dr Peter Dann and has been part of the Thomas suite since 2006.

Intelligence can be defined as having fluid and crystallised components:

- Fluid intelligence (pure processing speed) – this is used to solve new problems, use logic in new situations and identify patterns.

- Crysallised intelligence (learnt factors) – This is the ability to use learned knowledge and experience.

The GIA is concerned with fluid intelligence and looks at an individual’s speed of processing information and ability to learn and develop new skills, rather than measuring ‘IQ’.

Format

The General Intelligence Assessment consists of five online tests that rely on processes such as thought, language, decision making, learning and memory.

Each test measures a different cognitive function:

- Perceptual speed – measures the perception of inaccuracies in written material, numbers and diagrams, the ability to ignore irrelevant information and recognise similarities and differences.

- Reasoning – measures the ability to reason from information provided and to draw correct conclusions. It assesses the ability of an individual to hold information in their short-term memory and solve problems.

- Speed and accuracy – measures basic numerical reasoning. It measures the degree to which an individual can work comfortably with quantitative methods.

- Spatial visualisation – measures the ability to create and manipulate mental images of objects. It relates to the ability to work in an environment where visualisation skills are required to understand and execute tasks.

- Word meaning – assesses word knowledge and vocabulary by looking at the comprehension of a large number of words from different parts of speech and the ability to identify the words that have similar or opposite meanings.

The individual's score is determined by the speed and accuracy of their responses. Their scores are then compared to a norm group, to determine whether the scores are lower, higher or in-line with the majority of that population.


Reliability & Validity

The GIA has been subject to rigorous scientific testing to determine its reliability and validity as a psychological assessment. Various research studies have shown that the GIA is a consistent and valid measure of trainability.

The GIA is 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.

Frequently Asked Questions

  • What is the General Intelligence Assessment (GIA)?

    The General Intelligence Assessment (GIA) is an aptitude and ability test (or perceptual speed test) that helps employers predict how quickly an individual will adapt to a new role or regime.

  • How does the GIA work?

    The GIA is composed of online tests that measure an individual’s cognitive function in five areas: Reasoning, Perceptual Speed, Number Speed & Accuracy, Word Meaning and Spatial Visualisation.

    Their score is determined by the speed and accuracy of their responses and then compared to a norm group to determine whether the scores are lower, higher or in-line with the majority of that population.

  • What are the benefits of the GIA to an organisation?

    The GIA report gives you an estimate of an individual’s general intelligence and gives insights into their response to training, mental processing speed, concentration and fast track potential.

    As a result, the GIA can help you answer questions about your workforce including, ‘Can your people think on their feet?’, ‘Can they cope with the mental demands of the job?’, ‘Are they good problem solvers?’ and ‘How quickly they can they learn?’.
