This document describes the FOCUS on 5 system for writing instruction and assessment. It explains that FOCUS on 5 uses 5 domains (Organization, Style, Conventions, Content, and Focus) to analyze student writing and determine strengths and goals. Teachers give students writing prompts and assess their writing in the domains to establish a baseline. They then use this data to guide small group and individual instruction, setting goals and modeling strategies using mentor texts. The process continues as teachers analyze new student writing and reflect on progress. The overall system is presented as a menu-based approach to teaching writing.
