Registered with the British Psychological Society (BPS), which follows the guidelines of the European Federation of Psychologists Associations (EFPA), Thomas assessments meet stringent requirements for validity, accuracy and fairness unmatched by most market alternatives.
Thomas’ dedicated team of psychometrists and data scientists continually improves the accuracy of assessment outcomes through benchmark research and ever-expanding global datasets, enabling us to demonstrate reliability across languages and cultures.
To minimise the impact of geographical, cultural and other potential biases on our assessments, we continually undertake research and development to ensure assessment results are balanced and fair across diverse cultures, languages and demographics.
