Thomas International is a long-established UK psychometrics provider, and so if you're looking at alternatives it might be they are just not the right fit for you. If you are in the market for something different, three of the best alternatives are listed below.
Clevry
Clevry is a UK provider of ability tests, personality questionnaires and situational judgement tests, and one of the most transparent on pricing. Its prices are published on its website, its subscription plans include unlimited candidates, and there's a pay-as-you-go option for teams that hire less often. Reviewers on G2 rate it 4.4 out of 5 and most often praise its ease of use and reports that managers can read without specialist training.
Its range is narrower than some larger providers, and it's less AI-resistant than Thomas' GIA. A good fit if you value simplicity and predictable costs, but likely not an improvement on Thomas.
Alva Labs
Alva Labs offers a short, modern assessment built on two tests: an adaptive logic test and a Big Five personality test, each taking around 15 minutes and both independently certified by DNV. Moving from Thomas's DISC-based approach to the Big Five means results are based on the most widely researched model of personality, and Alva puts a strong emphasis on transparency, with candidates receiving the same report the recruiter sees. Support is one of its most praised features on G2.
The flip side of that simplicity is that some managers find the reports too light when they want more detail, and again the tests will be less AI-resistant.
Test Partnership
Test Partnership's strength is modern, adaptive cognitive and behavioural assessment, supported by technical evidence and flexible implementation. Every test is developed by business psychologists and trialled on tens of thousands of participants from mixed backgrounds, and supported by technical evidence on reliability, validity and adverse impact.
On the behavioural side, our personality questionnaires are grounded in the Big Five, and no training or certification is needed to use them or read the results, so any hiring manager can pick up a report and act on it.
I like the format of their soft skills, numerical reasoning, verbal reasoning tests and reports. They are easy to understand with the necessary level of detail to help us make the best hiring decisions. For an SME like us, Test Partnership makes hiring easier and cost effective.
We can build a bespoke assessment around your own competencies, values or the traits your highest performers share. Vitality, for example, worked with us on a validity study to identify the behaviours linked to success in their roles, which became the basis of a custom assessment to identify the applicants most likely to stay, be engaged and perform well.
On AI, Thomas's GIA gets some built-in resilience from its quick-fire format. Our Signals series works on a similar principle, with a short time limit on each question, and gives you considerably more protection than a traditional test. For something much more AI-proof, MindmetriQ, our gamified cognitive assessments, is designed so that AI can't assist at all, as the reasoning happens through interacting with game-based tasks rather than answering static questions. Each test takes just 4 to 6 minutes.
Conclusion and next steps
Thomas International is a credible provider with a long track record, and for many organisations it's the right choice. If you're exploring alternatives, the best way to decide is to compare providers on the evidence behind their assessments, the candidate experience and their resilience to AI. Clevry offers simplicity and transparent pricing. Alva Labs offers a short, candidate-friendly experience. Test Partnership offers modern, adaptive cognitive and behavioural assessment, supported by technical evidence, AI-resistant assessment design and flexible implementation.
