The Computational and Algorithmic Thinking (CAT) competition is a problem-solving competition designed by the Australian Maths Trust (AMT) to encourage student curiosity and promote computational thinking. It is the pre-competition of Oxford University Computing Challenge (OUCC). Build on CAT with the Oxford University Computing Challenge (OUCC)

​

Participants DO NOT need any computer programming ability, but the competition helps identify students’ computer programming potential and encourages students to solve real-world problems. It is suitable for any mathematics class, and the process helps students become more confident as they take on interesting new challenges. 

​

The CAT has four divisions:

Upper Primary (NZ years 6–7),

Junior ( NZ years 8–9),

Intermediate (NZ years 10–11) and

Senior (NZ years 12–13).
