What is the science behind Thomas Assess?
Thomas Assess is built on well-established psychological models and validated by independent research. It includes:
Behavior – based on the DISC model, measuring how people communicate, respond to pressure, and interact with others.
Personality – using the High Potential Trait Indicator (HPTI), grounded in the Big Five personality model, to assess traits linked to leadership and role fit.
Aptitude – through the General Intelligence Assessment (GIA), measuring fluid intelligence and how quickly someone can learn and adapt.
Emotional Intelligence – using the Trait Emotional Intelligence Questionnaire (TEIQue), developed by leading psychologists to assess self-awareness, resilience, and social effectiveness.
All assessments are developed by experts, independently validated, and designed to deliver insight you can trust.
Why use psychometric assessments?
Psychometric assessments give you objective insight into how people think, work, and interact. They have repeatedly been proven to help predict job performance and cultural fit far more accurately than CVs or interviews alone. In fact, research shows that cognitive ability tests are one of the strongest predictors of job success (Schmidt & Hunter), and that organizations using assessments see up to 24% higher new hire performance and 36% better retention (Aberdeen Group).
That’s why Thomas Assess combines multiple leading assessments into one easy-to-use platform, giving you validated insight you can trust — without needing to be a psychologist. From behavior and personality to aptitude and emotional intelligence, it gives you the data you need to build high-performing teams.
How does Thomas Assess keep candidate data secure?
Thomas Assess is built with security and ethics at its heart. All data is securely stored and processed in line with GDPR and global data protection standards, with strict access controls and psychologist-led ethical guidelines to ensure personal data is handled responsibly and transparently.
