Thomas General Intelligence Assessment (GIA)

A candidate’s aptitude for learning new skills and information is a factor you should consider when making hiring decisions. It’s also valuable knowledge to have when creating a development plan for your employees, during onboarding and beyond. This is why the Thomas GIA is such an important tool and resource for managers.

How Does This Assessment Work?

Split into five separate sections, the Thomas General Intelligence Assessment (GIA) measures your candidate’s ability to learn and perform new skills. The GIA takes both speed and accuracy into consideration when scoring the candidate’s answers. The five areas that are measured as part of this assessment are as follows:

  • Reasoning
  • Perceptual Speed
  • Number Speed And Accuracy
  • Word Meaning
  • Spatial Visualisation

Reasoning

Does your candidate have solid reasoning skills? Are they able to take the evidence in front of them and come to a logical conclusion? This section tests this area of their intelligence.

Perceptual Speed

Does this person have a keen eye for detail? Are they more or less likely to notice errors? Do they find it easy to tell the difference between relevant and irrelevant information? The perceptual speed section of the GIA will provide answers to these questions.

Number Speed And Accuracy

How does your candidate fare when it comes to numerical reasoning? Are they able to work with numbers in a efficient and accurate way? Do they have high levels of attention and concentration when dealing with numerical problems? This section will reveal the answer to these questions to you.

Word Meaning

Does your candidate have an extensive vocabulary? Are they able to identify and understand instructions well? The Word Meaning section of the GIA provides an overview of their part of your candidate’s intelligence.

Spatial Visualisation

This section of the assessment looks at the candidate’s aptitude for mechanical reasoning, offering them a selection of puzzle-like questions which require them to identify whether shapes are the same are different when rotated or inverted.

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.
