Thomas International is a UK-based assessment company best known for the Personal Profile Analysis (PPA) — a DISC-based personality questionnaire — and the General Intelligence Assessment (GIA), a timed aptitude battery. Thomas assessments are widely used by UK recruitment agencies, SMEs, and mid-market companies, particularly for sales, management, and customer-facing roles. You're more likely to encounter Thomas assessments through a recruitment agency than directly from a large employer.
The PPA is a 24-item forced-choice questionnaire based on the DISC model (Dominance, Influence, Steadiness, Compliance). Takes 8–10 minutes. For each group of four adjectives, you select which most and least describes you. The result is a DISC profile — four bars showing your relative levels of each trait — and a narrative report interpreting your working style, motivators, and behavioural tendencies. There are no "right" answers, but employers screen for profiles matching the role's requirements (e.g. high Dominance and Influence for sales leadership; high Compliance for quality assurance).
A timed aptitude battery testing five cognitive dimensions: reasoning, perceptual speed, spatial visualisation, number speed and accuracy, and word meaning. Strictly timed (varies by section but typically 2–5 minutes each). The GIA produces a score from 1–9 (STE score — Standard Ten) for each dimension and an overall GIA score, compared to a working age norm. Employers typically set minimum GIA thresholds for specific roles — a GIA of 6+ (60th percentile or above) is commonly required for managerial roles.

As of 2026, Thomas International's assessments have maintained their structured formats to effectively evaluate candidates' cognitive and personality traits. The General Intelligence Assessment (GIA) comprises five sub-tests: Reasoning, Perceptual Speed, Number Speed and Accuracy, Word Meaning, and Spatial Visualization. Each sub-test is designed to be completed within 2 to 5 minutes, culminating in a total assessment duration of approximately 30 to 45 minutes, including instructions and practice examples. This structure ensures a comprehensive evaluation of a candidate's learning agility and problem-solving capabilities.

Recent candidate experiences highlight the importance of familiarity with the assessment's unique format. The GIA test, for instance, presents around 200 questions to be answered in under 20 minutes, demanding exceptional focus and quick decision-making. Candidates have found that practicing under timed conditions and becoming accustomed to the rapid pace significantly enhances performance.

In response to evolving recruitment needs, Thomas International has emphasized the integration of their assessments into the broader hiring and development processes. The GIA, for example, is utilized not only for recruitment but also for retention, development, management, identifying training needs, career guidance, succession planning, and benchmarking. This holistic approach allows organizations to leverage assessment insights throughout the employee lifecycle, ensuring alignment between individual capabilities and organizational objectives.
