The Coding Challenge is designed to be accessible to all students, even if they have basic coding skills. There are five levels (or divisions), and teachers are able to enter their students at the most appropriate level based on skills rather than age.

Tasks require Turtle Blockly solutions or a text-based programming language, depending on the division.

Practice challenges can be found on the UK Bebras website

*This challenge replaces the Oxford University Computing Challenge (OUCC). There is only one round for this challenge.

  • Pathfinder
  • Trailblazer
Novice and Explorer tasks require Turtle Blockly solutions. The other divisions use text-based programming languages including Python, C#, Java and VB. A full list of supported languages can be found here.
