The document outlines the CSP Code, a proofreading code used at Clevedon School. It consists of 5 components: C for capital letters, S for spelling, P for punctuation, // for paragraphs, and ? for parts that don't make sense. For each component, the document provides guidelines on when to use the code and what errors to mark. The overall goal of the CSP Code is to help students thoroughly proofread their writing and catch any issues with capitalization, spelling, punctuation, paragraph structure, or meaning.
