The purpose of this study was to examine the effects of teaching functional digital literacy skills to three high school students with intellectual disability. Functional digital literacy skills included sending and receiving email messages, organizing social bookmarking to save, share, and access career websites, and accessing cloud storage to download, revise, and upload documents. Results indicated that all students acquired and maintained these functional digital literacy skills. Findings are discussed in the context of teaching essential digital literacy skills to increase greater participation in a digital society.
