Abstract

The aim of this scoping review was to explore the extent to which AAC studies have occurred in inclusive versus segregated settings, the role of AAC in inclusive setting studies, and the evidence for AAC supporting inclusive education of students with complex communication needs. A scoping review of studies published from 2000 to 2020 that involved students who used or could benefit from AAC or their peers conducted within schools yielded 167 studies. Relatively few studies (n=28, 17%) were conducted in inclusive settings. Data from these 28 studies were extracted and appraised for quality. AAC was integrated into intervention in 57% of these studies and in 61% improved use of AAC was an outcome variable, but in only six was this the main aim. Eighty-two students who used or could benefit from AAC were participants across studies. Classroom peers participated across 11 studies, including those in which qualitative designs were employed. The strength of evidence for the role of AAC could not be determined because only 12 studies were experimental and addressed varied aims. Nonetheless, these and seven qualitative studies were appraised as being of high quality. Implications of findings are discussed in terms of extending the evidence to demonstrate the role of AAC, and its potential to support academic and social school inclusion of students with complex communication needs, which may not rely on proficient use of AAC.
