General Intelligence Assessment
What is the GIA assessment?
The GIA assessment (General Intelligence Assessment) is a timed cognitive test used by employers to measure how quickly you process information. It is not a knowledge test — it rewards speed and accuracy across five short sections.
The five GIA assessment sections
The Thomas GIA test — also called the General Intelligence Assessment — covers Reasoning, Perceptual Speed, Number Speed & Accuracy, Word Meaning, and Spatial Visualisation. Each section uses a distinct question format under time pressure.
Candidates who have seen each format before perform better because they spend less time decoding instructions. Free timed practice is the most effective way to build that familiarity before your real GIA assessment.

GIA assessment FAQs
What is the GIA assessment?
The GIA (General Intelligence Assessment) is Thomas International’s timed cognitive test. It measures how quickly you absorb information and respond accurately across five short sections, not how much you already know.
Who uses the Thomas GIA test?
Employers use the Thomas GIA during recruitment to assess processing speed, trainability, and problem-solving pace. It is common in roles where learning quickly on the job matters more than prior specialist knowledge.
How long does the GIA assessment take?
The full assessment is short but intense — candidates face many quick-fire items across five sections under strict per-question time pressure. Total sitting time is typically well under half an hour.
How is the GIA assessment scored?
Each section combines speed and accuracy. Raw scores are standardised against a norm group and reported as percentiles. Answering quickly and correctly matters more than attempting every single item.
