Choose this modeWhat the five GIA tasks look like
The tasks are short and repeat their rules. Practice understanding each rule, then answering consistently as the details change.
Perceptual Speed
Compare four vertical pairs of letters. Count matching letters, treating uppercase and lowercase as the same.
Try this: Scan each column once. Similar-looking letters still need to be the same letter.
Practice this skillNumber Speed & Accuracy
Find the highest, middle and lowest of three numbers. Choose the extreme that is farther from the middle number.
Try this: Compare the two gaps. The highest number is not always the answer.
Practice this skillWord Meaning
Find the odd word out of three. The related pair can have similar meanings or opposite meanings.
Try this: Look for a clear relationship between two words before choosing the third.
Practice this skillSpatial Visualisation
Compare two pairs of symbols. Count the pairs that can match by rotating; a mirror image cannot count as a match.
Try this: Follow an asymmetric feature around the shape. Turning and reflecting are different.

Prepare for the assessment in your invitation
Thomas’s current candidate guide describes five timed tasks and 30–45 minutes overall, including instructions and practice. It requires a desktop or laptop for the real assessment. Read its free official example booklet before your test.
Our practice follows the five task mechanics using original questions and symbols. Choose two-minute skill drills or three minutes per section in combined practice. These are our training presets. We show practice accuracy and pace, without official scores, percentiles or a predicted hiring result.
The combined sitting has an untimed transition before each new section. Once a timed section starts, its clock continues through background tabs and reloads. Learning mode lets you review each answer before continuing.
Applying to Canonical?
Canonical’s hiring process includes a five-part GIA alongside other assessments and interviews. Use these drills to learn the task mechanics, and follow your invitation for the assessment itself. A practice result does not determine whether you will progress.
Thomas GIA practice questions
What is the Thomas GIA test?
The General Intelligence Assessment, also called Thomas Aptitude, is a series of five speeded tasks: Reasoning, Perceptual Speed, Number Speed & Accuracy, Word Meaning and Spatial Visualisation. These exercises practice those task mechanics using original content.
How long is the real Thomas GIA?
Thomas’s current candidate guidance describes five tasks lasting two to five minutes each, with 30–45 minutes overall including instructions and practice. Its example booklet says there are eight practice items before each task. Follow your invitation for the actual assessment. Our two-minute drills and three-minute sections are practice presets, not verified official section time limits.
Why do the questions look simple?
The challenge is to keep making quick, accurate decisions as similar items change. Learn the rule without a timer, then use a speed drill to find a pace you can sustain. More difficult preparation here means handling comparisons, close numerical gaps and rotated symbols accurately under pressure, rather than introducing unrelated advanced puzzles.
Does this give me an official GIA score or percentile?
No. Your results show correct and incorrect responses, unanswered items, accuracy and pace for our practice content. They are not standardized Thomas scores, IQ estimates or employer pass predictions. Compare your own practice using the same skill, mode and device.
Can I try the format for free?
Yes. The familiarization examples on this page are free without an account and do not consume a practice attempt. Your access to saved practice is shown before starting. A dedicated Thomas GIA pass covers all five skill drills and the combined sitting; other assessment categories have separate passes. Saved answers and explanations remain free to reopen.
Can I use my phone?
Our practice works on smaller screens, but Thomas’s current candidate instructions require a desktop or laptop for the real GIA. For timed preparation, use a desktop or laptop with the pointing device you plan to use. Scores from different devices are not directly comparable.
Is GIA the same as the Thomas personality assessment?
No. Thomas GIA is an aptitude assessment. Thomas Behavior, also called PPA, and the HPTI personality assessment are different products. This track prepares the five GIA skills; it does not provide answers to personality questionnaires.
