Writing can be a method of expression for those who cannot or do not feel comfortable expressing themselves verbally. For students with disabilities, however, writing can be a challenging task because they often fail to see writing as a process. This article examines how to use the self-regulated strategy development model of writing, an evidence-based practice, to teach middle and high school students with emotional/behavioral disabilities to use persuasive writing as a tool to advocate for their needs and wants. Writing can help students develop self-determination skills and self-expression with the time needed to reflect on what they want to say, making the process of writing an empowering one. Example lessons, guidelines, and sample materials are provided.
