Alternative and augmentative communication (AAC) encompasses a range of tools and strategies that facilitate communication for individuals with communication difficulties (Hartzheim, 2017). One of augumentative and alternative communication systems is communication boards. Communication boards belong to low-tech AAC systems. They can be used by anyone with complex communication needs for various reasons. Individuals with complex communication needs refer to those who are born with communication difficulties/inability to communicate in the usual way or acquire these difficulties later in life. This study focused on public communication boards. Like regular communication boards, they are low-tech system of AAC, but they are placed in various public places (parks, playgrounds, waiting rooms, kindergarten and school yards, etc.). The aim of this study was to assess parental satisfaction, awareness, and attitudes regarding public communication boards, as well as to examine differences in satisfaction and usage (by parents and children) based on whether children typically use any AAC system. For this research, a questionnaire was developed, which parents filled out electronically. The study involved 213 participants, all of whom were parents of children with complex communication needs. The results indicated that parents of children who typically use some form of AAC also tend to use public communication boards more frequently in interacting with their child compared to parents whose children do not typically use AAC. However, there were no differences in children's usage of public communication boards based on whether they typically use AAC or not. The research also revealed that parents are satisfied with the appearance of public communication boards but are dissatisfied with their number and their promotion, i.e., informing the public about their existence.
