Research has shown that using Picture Exchange Communication System (PECS) and Speech Generating Devices (SGD) helps in the increase of verbal communication in those with limited verbal communication. The purpose of this study was to 1.) Investigate the impact of various low-technology and high-technology on the increase in social-communicative behavior in individuals with limited verbal communication and 2.) Create a resource of PECS and SGD, and their uses, to guide teachers and other educators to determine which device best fits the student’s communication needs. Qualitative and quantitative research design, surveying educators from four Northeast Indiana schools, was used in this study. The survey, which included force-choice and open-ended questions, was distributed to educators, including specials teachers, paraprofessionals, and speech language pathologist, in the general and special education setting. Seven educators completed the survey. Research showed that based on the devices used within the school, teachers agreed that augmentative and alternative communication devices were beneficial for various aspects of communication for students with limited verbal communication within the classroom.
