Employers worldwide are increasingly testing candidates for artificial intelligence skills as hiring moves towards technical and cognitive capability, according to new figures.
An analysis, covering 3.9 million skills tests taken globally, found that AI testing has risen by 166 percent in the past year, representing the fastest growth across all skills evaluated. Coding Debugging tests increased by 133 percent while Computer Literacy and Data Structures (Arrays) rose by 77 percent and 73 percent respectively.
It reflects a “dramatic shift” towards AI proficiency as organisations adapt to automation and data-driven decision-making, according to talent assessment firm TestGorilla, which carried out the research. The findings also show that critical thinking, problem solving and attention to detail remain among the most widely tested skills worldwide.
UK data points to data-driven roles
In the UK, Market Analysis was the fastest-rising skill test, up 198 percent year-on-year, followed by Technical Support Help Desk Representative (+188%), Typing Speed (+164%), WordPress Administration (+118%) and Project Management (+85%).

The company said this shows strong demand for candidates who combine digital fluency with analytical and operational ability. Employers appear to be focusing on technical competence rather than formal qualifications as hiring processes evolve.
Attention to Detail remained the most popular test among UK employers, ahead of Communication, Problem Solving, Critical Thinking and the Big 5 (OCEAN) personality assessment. Globally, the Big 5 test ranked first, followed by Attention to Detail, Critical Thinking, Communication and Problem Solving.
Employers close the AI skills gap
The report comes as businesses worldwide attempt to address growing skills shortages in artificial intelligence. It noted that while interest in AI testing has surged, many employers still fail to screen for these capabilities in interviews. And it cited findings from Harvard Business Review showing that 93 percent of candidates were not asked about AI skills during recruitment.
Wouter Durville, chief executive and founder of TestGorilla, said the data reflected how rapidly hiring priorities were changing. “This data shows that the global skills landscape is evolving fast, and employers are waking up to the reality that CVs and interviews alone can’t reveal true capability,” he said.
Durville said the report found that “71% of employers say skills testing is more predictive of on-the-job success than resumes”.
He added that the “difference is only going to increase as AI reshapes the world of work and the demand for precise tools to measure candidate proficiency grows.
“Organisations are increasingly looking towards skills tests as the most objective and fair way to assess technical proficiency and capacity to work alongside AI effectively.”
Building ‘AI-first’ teams
Olive Turon, head of people and culture at TestGorilla, said employers were now embedding AI awareness into hiring and leadership decisions. “Most leadership teams right now are thinking about how to build an AI-first company, and, as a result, every modern recruiter is thinking about AI-first hiring,” she said. “In other words, how to hire people who can excel in an AI-driven world.”
Turon added that skills tests were now essential for measuring technical ability and critical thinking. “Skills tests that are designed to objectively measure technical ability and critical thinking, especially those with robust anti-cheating measures built in, are crucial for recruiters to have available as they build their AI-first teams,” she said.
A move towards skills-based hiring
The dataset tracked more than 350 science-backed assessments used by employers across industries. Between January and August this year, over 312,000 tests were completed by UK-based candidates, part of 3.9 million taken globally.
The results indicate a broader move away from traditional hiring filters such as academic background towards more objective, data-driven evaluation. The company said employers are prioritising what candidates can do rather than how they present themselves on paper — something that’s likely to increase as AI becomes embedded in most workplace functions.
