Alva's hiring system is grounded in decades of psychometric research. Our contribution: adaptive testing powered by IRT and Bayesian inference, calibrated on 1.5 million candidates, and independently certified by DNV.
One of the world's most cited researchers on hiring and selection. His 2022 meta-analysis with colleagues aggregated thousands of validity studies to answer a deceptively simple question: which hiring methods actually predict job performance? The findings changed the consensus, and directly shaped how Alva's system is designed.
“Dig deeply into a job, figure out what's important, put together questions linked to the crucial attributes of a job and treat every candidate consistently. And man, you've got a tool that's really quite effective.”
Dr. Paul Sackett, Professor of Psychology at the University of Minnesota and past president of SIOP.
“Bayesian IRT gives us something no one else in this market has: control. We can add items, remove bad ones, recalibrate the model, and push updates to every candidate and recruiter at once. Most competitors train their model once and leave it untouched for five to ten years. We retrain continuously.”
Morgan Pihl, former Head of R&D, now scientific advisor to Alva Labs
Every assessment is independently certified by DNV. Every AI decision is auditable. Every data point is protected by ISO 27001 and stored within the EU. We didn't wait for regulators to set the bar. We set it ourselves.
Independent third-party validation of scientific rigour and practical utility. Two reviewers, documented non-conformities, 3-year recertification cycle. Next audit: March 2028.
Full assessment methodology (Define, Assess, Decide) independently certified under the global standard for assessment service delivery and quality.
ISO 42001 certified for AI management systems, one of the first companies globally. Built for compliance before the regulation requires it.
All psychometric tests developed using IRT and Bayesian inference. No candidate data processed by external LLMs. No black-box scoring. Full control over every model update.
We can show what data the model used, how it was weighted, and why it produced a particular score. Full traceability from input to output.
ISO 27001 certified. Candidates own their data. 24-month default retention with automated deletion. All data stored on Google Cloud within the EU.
“For us, it has been important to find a way of working that makes recruitment more fair, more accurate, and less dependent solely on CVs, without compromising on our requirements for security and compliance. Alva has become an important part of that work.”
