What to expect from the APTITUDE assessment

The Thomas Aptitude Assessment (GIA) measures how quickly someone can learn, adapt, and succeed in a role — not just what they already know.*

It evaluates five key areas that impact workplace performance:

Reasoning: How well they interpret verbal information, connect the dots, and draw the right conclusions.
Perceptual speed: How quickly and accurately they spot errors, match information, and filter out what doesn’t matter.
Number speed and accuracy: How confidently they handle numerical information, compare numbers, and work with quantitative concepts.
Word meaning: How strong their vocabulary and comprehension are — and how effectively they understand written and verbal information.
Spatial visualization: How well they can picture and mentally manipulate shapes or patterns, and understand how different parts fit together.

Combine it with Behavioural, Personality and Emotional Intelligence assessments in Thomas Assess for a complete view of each candidate’s potential.

*This assessment is not intended for candidates to practice for a job interview.
