Historically and in recent years, the National Writing Project has focused its efforts on supporting the teaching of writing in low-income and underserved schools, districts, and communities. NWP's i3 College-Ready Writers Program (CRWP) grant supported 12 writing project sites in providing professional development in 22 rural school districts. Specifically, this work focused on improving the teaching of source-based argument writing and engaging young people in writing high-quality, source-based arguments in school. This work continues through the CRWP SEED Advanced Institutes and the CRWP in High-Need Schools grants. These grant programs continue NWP's commitment to equity and social justice by supporting teachers and students in economically poor communities. Join three NWP leaders as we discuss the value and importance of NWP work in high-need schools, and how the CRWP resources can support that work.
