The document provides information about a competition for UK secondary school students to design a rat sculpture to be displayed on the Fourth Plinth in Trafalgar Square, London. Students are instructed to use Banksy's stencils of anti-social rats as inspiration and create a sculpture that comments on an issue affecting Londoners.

The competition aims to select the best rat sculpture from each class to be exhibited at the school and submitted to the Fourth Plinth Secondary Schools Competition.
