The PPA behavioural profile, the GIA speed test and its five sections, and the HPTI and TEIQue questionnaires. What each one asks, how long you get, why speed counts on the GIA and honesty on the rest, and what the employer sees at the end.






A Thomas test is a workplace psychometric test from Thomas, the UK company formerly known as Thomas International. The two best known are the PPA behavioural profile, a DISC based questionnaire of 24 forced choice question sets taking about eight minutes, and the GIA aptitude test, a speed based measure of reasoning, perception and number and word skills lasting 30 to 45 minutes overall. Personality and emotional intelligence questionnaires round out the range.
Which Thomas International test you sit depends on the employer and the role: an entry-level position will not be given the same assessment as a graduate or managerial one.
Four things to know before you sit one. Timings and difficulty vary with the level of the role.
Match the name in your invitation to the assessment below. Timings marked “approx.” are completion estimates; other published durations are limits for the named version.
| Assessment | What it measures | Questions | Timing |
|---|---|---|---|
| PPA (Personal Profile Analysis) | DISC working style, from 24 sets of four adjectives | 24 sets | Untimed; approx. 8 min |
| GIA (General Intelligence Assessment) | Perceptual speed, reasoning, number speed and accuracy, spatial visualisation, word meaning | Five timed sections | 2 to 5 min per section; allow 30 to 45 min total |
| HPTI (High Potential Trait Indicator) | Six leadership traits, from conscientiousness to competitiveness | 78 statements | Untimed; approx. 8 to 10 min |
| TEIQue (Trait Emotional Intelligence Questionnaire) | How you handle your own and other people's emotions | Varies by version | Untimed |
Counts and timings vary by role level and by the version an employer licences. Check the instructions on the screen before you start. Facts checked 11 September 2026.
PPA, HPTI and emotional intelligence questionnaires are untimed. GIA’s total includes instructions and practice, with separate timed sub-tests.

Based on 784 completed practice sittings, all time. Checked 11 September 2026.
The 75th percentile marks the boundary of the top quarter of recorded scores; tied scores can share that boundary. These are our practice results, not employer pass marks.
We use all-time completed, scored attempts at this practice test. Repeat attempts count separately, so the sample is sittings rather than unique people.
The average is the mean score across those sittings. The 75th percentile comes from their recorded score distribution. The “checked” date is when we retrieved the figures, not the period when the tests were taken.

One question tells you the style. A pack gives you the pace: timed and marked, with the working shown.
The Personal Profile Analysis has 24 questions and typically takes about eight minutes and is untimed. Each question shows four adjectives and you choose the one most like you and the one least like you at work. Far from a test in the usual sense, it is a chance to show what makes you tick, so that an employer can judge whether you are likely to fit the role and the company.
The four traits it profiles are:
Answer openly and honestly. Keeping the company’s values and the role’s key competencies in mind does no harm, but an inconsistent profile is worse than an honest one.
The General Intelligence Assessment is timed and scored on speed as well as accuracy, so work through the questions as quickly as you can without giving up precision. Allow 30 to 45 minutes including instructions and practice. The five timed sections each take between two and five minutes:
Where most psychometric tests measure one ability, the GIA measures several at once, which is why employers use it to judge how quickly you will learn a role as well as how you will perform in it.
The High Potential Trait Indicator assesses six workplace personality traits and is most often used to identify future senior leaders: conscientiousness, adjustment (coping under pressure), curiosity, approach to risk, ambiguity acceptance and competitiveness. You rate statements rather than answer questions, and there are no right answers.
The Trait Emotional Intelligence Questionnaire is untimed and asks how strongly you agree or disagree with a series of statements about handling your own emotions and other people’s. Employers use it to judge communication style and potential to adapt and lead. As with every personality assessment, honesty and consistency matter more than any tactic.
What candidates ask us most often
No. The PPA is a profile of your working style across dominance, influence, steadiness and compliance, not a scored test. The employer reads the profile against the role, so the risk is not a low score but an inconsistent one. Answer as you actually work, not as you think the job wants.
Perceptual speed (spotting errors in text, tables and numbers), reasoning (drawing conclusions from short passages), number speed and accuracy, spatial visualisation (mentally manipulating shapes) and word meaning (picking the word that does not belong). Each is short and timed: the numerical and spatial sections are the ones most candidates practise.
Because the GIA is scored on how many questions you answer correctly in the time, and the questions themselves are simple. Working steadily through them beats agonising over any one, and the instructions and practice before the test are the time to slow down, not the test itself.
Yes. Thomas International rebranded as Thomas, and the assessments kept their names, so an invitation to a Thomas PPA or GIA is the same test described here.
Rated 4.7 out of 5 across 75 reviews. A selection:
The test was more time-consuming than I expected. I'm happy I did this practice test before attempting the real one.
The questions although you would believe tricky are straightforward if you think logically and do not rush.
I like that it can test out the knowledge of mathematics, but around 1 min average for each question is not quite enough.
