Perse Coding Team Challenge: think as a team

Editorial overview

The Perse Coding Team Challenge is not simply an individual contest with adjacent laptops. Teams solve text-programming problems online at school, with two pupils in the first round and three in the final. That change in team size reveals the competition’s real demand: students have to distribute attention, share discoveries and combine work under a fixed window.

The event is open across Years 7–11 and equivalents, with international schools able to participate for certificates under the current official description. The strongest Round 1 performers move towards a harder final. A team that assigns every problem to its fastest coder wastes the format; the bottleneck soon becomes reading, testing or explaining rather than typing.

CompeteMap recommends PCTC to students who already write text-based programs and can accept peer review. It is less suitable as a first introduction to syntax. Preparation should include shared conventions for input, output, test cases and handover, because team speed disappears when nobody can understand another person’s code.

Quick Facts

Review Evaluation

Rated Advanced. Teams need reliable text coding, strategic allocation and mature multi-part work under timed conditions.

Checked on 26 September 2026.

Allocate after a full scan

Read the whole problem set before coding. Assign an owner and a reviewer, then agree when a stuck solution returns to the team. Parallel work helps only when discoveries are shared.

Standardise the handover

Use the same input parser, test checklist and naming habits. A teammate should be able to run and inspect another solution quickly. Practise explaining a bug in one minute without taking over the keyboard.

Key Takeaways

• PCTC tests collaboration as well as programming.
• Scan and allocate problems before committing the team.
• Shared testing and handover habits are the highest-value preparation.
