Did a few runs before my Thomas GIA and it actually helped. The timer keeps you honest and the answer review at the end is useful - I kept messing up perceptual speed until I saw where I was going wrong. Free and no signup is a bonus.
About the assessment
What is the Thomas GIA test and GIA assessment?
The Thomas General Intelligence Assessment (GIA) — also called the GIA assessment or GIA test — measures cognitive processing speed. It shows how quickly you can absorb information, reason with it, and respond accurately. Employers use it during recruitment to gauge trainability and problem-solving speed rather than acquired knowledge.
The assessment is made up of five individually timed sections, each with a distinct question format. Questions are simple by design; the challenge is answering many of them quickly and accurately. That makes familiarity with each format the single most effective way to prepare — which is exactly what free timed GIA test practice gives you.

Test structure
The five GIA sections explained
01
Reasoning
Read a short comparative statement (e.g. “Anna is taller than Ben”), hold it in mind, then answer an inference question such as “Who is shorter?”. Tests verbal working memory and deduction speed.
02
Perceptual Speed
Four pairs of letters are shown. Count how many pairs contain the same letter of the alphabet, ignoring case. Tests speed and accuracy of visual checking.
03
Number Speed & Accuracy
Three numbers are shown. Take the highest and the lowest, and pick whichever is furthest from the remaining number. Tests numerical reasoning at speed.
04
Word Meaning
Three words are shown, two of which are related in meaning (similar or opposite). Pick the odd one out. Tests vocabulary and verbal reasoning.
05
Spatial Visualisation
Pairs of abstract figures are shown. Decide in how many pairs the second figure is a rotation — not a mirror image — of the first. Tests mental rotation ability.
Procedure
How this GIA test practice works
- Choose all five sections or drill a single one, and set how many questions you want per section.
- Every attempt draws a fresh randomized set of questions, so retakes stay useful.
- A total time limit matching the real GIA pace (about six seconds per question) keeps the pressure realistic.
- You get an instant score with correct/incorrect counts, time taken, and a full question-by-question review with explanations.
- Your history is saved locally in your browser — nothing is sent to a server and no account is needed.

Frequently asked questions
What is the Thomas GIA test?
The Thomas General Intelligence Assessment (GIA) is a timed aptitude test used by employers to measure how quickly a candidate can process information. It consists of five short sections — Reasoning, Perceptual Speed, Number Speed & Accuracy, Word Meaning, and Spatial Visualisation — each testing a different cognitive skill under time pressure.
What is the GIA assessment?
The GIA assessment (General Intelligence Assessment) is Thomas International’s timed cognitive test. It measures processing speed across five sections rather than learned knowledge. Employers use it in recruitment to gauge how quickly someone can absorb information and respond accurately.
How is the Thomas GIA test scored?
Each section is scored on both speed and accuracy. Raw scores are converted to standardised scores and percentiles by comparing your performance against a norm group of previous test takers. Because the test rewards speed, answering quickly and accurately matters more than finishing every question.
How can I improve my GIA score?
Familiarity is the biggest lever: knowing each question format in advance means you spend your time answering, not figuring out the rules. Take repeated timed practice tests, focus extra practice on your weakest sections, and build a steady fast rhythm rather than rushing.
Is this practice test free?
Yes. All practice tests on this site are completely free, with no account or sign-up required. Your results and history are stored only in your own browser.
Are these the same questions as the real GIA test?
The questions use the same five formats and a similar time pressure as the real assessment, so the skills you practise transfer directly. The exact questions on the real test will differ, but the format, logic, and pacing are what you need to master.
Is this site affiliated with Thomas International?
No. This is an independent practice resource and is not affiliated with, endorsed by, or connected to Thomas International. “Thomas GIA” is referenced only to describe the test format this site helps you prepare for.
