What is C3WP?

C3WP is an intensive professional development program that provides teachers with instructional resources and formative assessment tools for the teaching of evidence-based argument writing. Teachers in C3WP typically participate in 45 hours of professional development per year for two years, experiencing instructional materials of the highest quality, learning to analyze student work carefully to determine instructional next steps, and leading their students towards active participation in their communities through argument writing.
