Writing, as a critical academic skill, is receiving national attention -- joining the ranks of reading, mathematics, and science. The focus on increased writing performance standards for all students has implications for students with learning disabilities (LD), as these students are most likely to struggle with basic writing skills, and with expressing their ideas and demonstrating knowledge through written expression. Fortunately, research-based practices have been established for teaching students with LD across writing dimensions. In this chapter, instructional approaches for writing instruction, and current and future trends for addressing standards, are described.
