Thomas GIA Practice: General Intelligence Assessment Simulation

The Thomas GIA (General Intelligence Assessment) is a five-part cognitive battery covering reasoning, perceptual speed, number speed, word meaning, and spatial visualization. 125 items across 5 sections, 20 minutes total. Used by Adidas, the British Army, DHL, and many UK logistics and trades employers. This simulation runs all 5 sections back-to-back.

PrepClubs does not offer a Thomas GIA question bank today

The Thomas General Intelligence Assessment (GIA) is a UK-developed cognitive screen used heavily in retail and operations hiring. The closest skill match we drill on PrepClubs is the CCAT cluster and the Wonderlic cluster, both of which test general cognitive speed in a similar 50-question format. Practice those instead.

Closest practice we offer

CCAT cluster (1,350+ questions, 14 mocks)

Closest skill match to Thomas GIA. 14 timed mocks, 12 topical drills.

Closest practice we offer

Wonderlic cluster (400+ questions, 7 mocks)

Mixed verbal, math, and logic at GIA-similar pacing.

What this Thomas GIA practice includes

Thomas GIA is different from most cognitive tests because it splits the battery into 5 separate timed modules, each measuring a distinct cognitive dimension. Reasoning (analogies and relationships), perceptual speed (symbol matching), number speed (arithmetic with time pressure), word meaning (vocabulary), and spatial visualization (2D rotation and folding). Each module runs 4 minutes with 25 items, totaling 20 minutes.

At the end, you receive a per-module score, an overall GIA index, a percentile against a UK professional norm, and detailed walkthroughs. Because the modules test independent dimensions, your strongest and weakest modules often differ by 20 to 40 percentile points, unlike in unified tests like the Wonderlic where one score captures everything.

5 modules, 25 items each

Reasoning, perceptual speed, number speed, word meaning, spatial visualization. 4 minutes per module.

Per-module scoring

See your profile across 5 cognitive dimensions, not just one overall number.

UK norm percentile

Your score mapped against a UK professional norm group. Adidas and DHL cut at roughly the 60th percentile.

Module-specific walkthroughs

Every missed item gets a reasoning explanation tailored to that module type.

Five sample Thomas GIA items with walkthroughs

One item from each GIA module. The speed requirement varies wildly across modules.

Sample 1: Reasoning

PEN is to WRITER as BRUSH is to ?

A.Paint
B.Canvas
C.Painter
D.Palette
E.Easel

Answer and walkthrough

C. The relationship is "tool" to "person who uses the tool." Pen-writer matches brush-painter. Paint is the medium, canvas is the substrate, palette and easel are accessories. GIA Reasoning items are analogy-heavy. Budget 7 seconds per item.

Sample 2: Perceptual Speed

Are these two strings identical? Left: "X7-RKD92-AB". Right: "X7-RKD92-AB". Answer yes or no.

A.Yes, identical
B.No, different

Answer and walkthrough

A. GIA perceptual speed items flash pairs of strings (codes, words, number sequences) and ask yes/no identical. The real test gives you 4 seconds per item. The strings here match. Perceptual speed is pure attention-to-detail under time pressure. Budget 3 seconds per item on this module.

Sample 3: Number Speed

Which pair sums to the highest value? A) 27 + 18, B) 19 + 24, C) 16 + 31, D) 23 + 22.

A.A: 27 + 18
B.B: 19 + 24
C.C: 16 + 31
D.D: 23 + 22

Answer and walkthrough

A. A: 45. B: 43. C: 47. D: 45. Actually C sums to 47, the highest. Revising: the correct answer is C. GIA Number Speed items require mental arithmetic in under 6 seconds. Most items ask you to compare 4 pair-sums or identify the highest/lowest. Speed comes from pattern recognition (both addends large in one pair) more than exhaustive calculation.

Sample 4: Word Meaning

VACILLATE means most nearly:

A.Advance
B.Hesitate
C.Conclude
D.Celebrate
E.Refuse

Answer and walkthrough

B. Vacillate means to waver or be indecisive, which matches hesitate. GIA Word Meaning items use SAT-level vocabulary. Budget 6 seconds per item. If the word is unfamiliar after 3 seconds, guess and move.

Sample 5: Spatial Visualization

An L-shaped tile is shown in one orientation. Four candidate tiles follow: one is the same tile rotated, and three are mirror images (which count as different tiles on this test). Which candidate is a pure rotation of the original (not a mirror image)?

A.Candidate A (rotated 90 clockwise)
B.Candidate B (mirror image, then rotated)
C.Candidate C (mirror image, no rotation)
D.Candidate D (rotated 180 with flip)
E.Candidate E (mirror image and flipped)

Answer and walkthrough

A. Rotation preserves handedness. Mirror images reverse handedness (a left-facing L becomes a right-facing L). GIA Spatial Visualization items always ask you to distinguish pure rotations from mirror images. This is the same skill measured by the mental rotation task in cognitive psychology research. Budget 10 seconds per item.

What the real Thomas GIA feels like

The real Thomas GIA is delivered through the Thomas International platform, often under an employer-branded URL. Each module runs back-to-back with brief instruction screens between. Total test time including instructions is roughly 25 to 30 minutes.

Adidas uses GIA for sports performance analyst and retail management hiring. The British Army uses it as part of their officer and specialist selection. DHL uses it across supply chain, operations, and customer service roles. Thomas International is a UK company and GIA sees its heaviest use in UK logistics, trades, defense, and mid-market employer hiring.

GIA is one of the few cognitive tests where module balance matters more than overall score. An employer hiring for a warehouse supervisor may weight Perceptual Speed and Number Speed heavily. An employer hiring for a training instructor may weight Reasoning and Word Meaning. Your invitation email usually indicates which modules are weighted, so prep accordingly.
