A digital, AI-powered, formative assessment 

The Computational Thinking Challenge is a dynamic digital assessment that cultivates and evaluates computational thinking skills in learners. 

Computational Thinking for All

Designed to be accessible for all learners, our tool equips all learners to be future-ready by empowering them to thrive, innovate, and solve complex problems in the future.

Learn Through Fun Challenges

Designed with the learner in mind, our tool creates experiences that transform the way learners engage with critical 21st century skills. It feels like playtime - but with serious learning and results.

Gain Personal Insight

Designed to support self-directed learning, our tool breaks the boundaries of traditional assessment to provide learners with personalized insights. These insights help students identify their unique strengths, improvement areas, and chart a path forward to unlock their full potential.


The Computational Thinking Challenge emerged from Dr. Rina Lai's work at the University of Cambridge, where she led the research and development of the assessment tool. The tool has benefited thousands of learners, featured in academic conferences, and published in top international peer-reviewed journals.
