Thomas International GIA

Thomas GIA test guide

A practical guide to the General Intelligence Assessment: what each test measures, how the session is structured, and how to prepare for its speed.

5 timed tests
2-5 min per test
30-45 min including instructions
8 practice examples before each test

What to expect

Thomas describes the GIA as five short tests covering reasoning, perceptual speed, number speed and accuracy, word meaning, and spatial visualisation. The official example booklet says speed and accuracy are equally important.

  • Each test begins with instructions and eight practice examples before the scored section.
  • The individual tests are short, usually two to five minutes, so quick recognition matters.
  • The official example booklet describes a mouse-driven assessment; follow the instructions in your invitation.
  • MindMetric practice is representative preparation, not a copy of proprietary live questions.

Explore every section

Learn the mechanic first, then practise it without leaving the guide.

Section 1

Reasoning

Remember verbal comparisons and infer the correct relationship.

  • Read and simplify the comparison.
  • Keep the direction of the relationship clear.
  • Answer after the original information is no longer visible.

Section 2

Perceptual Speed

Compare character pairs quickly while ignoring irrelevant detail.

  • Scan each pair in a consistent direction.
  • Count only exact matches.
  • Confirm the count before selecting an answer.

Section 3

Number Speed & Accuracy

Manipulate simple numerical information accurately at speed.

  • Identify exactly what comparison or operation is requested.
  • Use mental arithmetic rather than writing a long solution.
  • Check the sign and direction before answering.

Section 4

Word Meaning

Recognise meaning relationships between words quickly.

  • Read all words before committing.
  • Find the closest pair in meaning.
  • Use context and word roots when a word is unfamiliar.

Section 5

Spatial Visualization

Mentally manipulate and compare symbols and shapes.

  • Choose one distinctive feature as an anchor.
  • Track rotation separately from reflection.
  • Compare orientation only after checking the internal marks.

How results are interpreted

GIA reports are interpreted by the organisation administering the assessment. Rather than chasing a fixed pass mark, train both reliable accuracy and faster decision-making across all five areas.

Build speed without losing accuracy

  1. Learn one question mechanic at a time without time pressure.
  2. Review errors and identify whether wording, calculation, or visual comparison slowed you down.
  3. Repeat short timed drills, then use a full test to practise switching between sections.
  4. Read every official instruction screen carefully because the interaction changes by section.

How long is the Thomas GIA?

Thomas says the complete session, including instructions, usually takes 30 to 45 minutes; each of the five tests lasts about two to five minutes.

How many sections are in the GIA?

There are five: Reasoning, Perceptual Speed, Number Speed and Accuracy, Word Meaning, and Spatial Visualisation.

Is there one fixed pass score?

No universal pass mark is published. Employers interpret results for their role and selection process.
