We started in 2009 by assessing engineers
Codility was founded in 2009 to answer a question: can this engineer do the work? Today, 1,300+ validated tasks across 80+ languages and frameworks assess practical skills in environments including VS Code and a terminal. Screen assesses candidates before interviews. Interview supports structured live technical interviews. Skills Intelligence assesses employees. Occupational psychologists design every task; subject-matter experts review it.
We assess engineering and AI skills for the whole company on one platform
Codility assesses engineering skills, including AI use, and extends the same approach to AI skills in sales, marketing, finance, operations and customer roles.
Industries we serve: financial services, consulting and IT services, automotive and electronics and technology.
Assessment science you can read
A published methodology
The Technical Manual documents the method and follows the Standards for Educational and Psychological Testing, the benchmark psychologists use to judge whether a test is valid and fair. No AI model scores a candidate, and your team makes the final decision.
An assessment science team
Tony Mellek, Head of Assessment Science, and James Meaden, Assessment Scientist, lead the team of occupational psychologists behind the method. They join customer calls on validation and fairness, and run local validation studies on a customer’s own roles and data.
Recognized work
The International Personnel Assessment Council gave its 2026 Innovations in Assessment Award to the Skills Intelligence proficiency scale and scoring methodology, for the paper “Applying Psychometric Science for Precise Technical Assessment”.
Every company now has to know who can get work done with AI
Companies need to know what their people can do with AI. We are building a standard for assessing that capability, drawing on our engineering expertise and extending it to business roles. We state what is true today and show the evidence.
