What does PECS stand for?

The correct term that PECS represents is "Picture Exchange Communication System." This communication approach is primarily designed to assist individuals, particularly those with autism or other communication challenges, in expressing their needs and desires through the use of pictures. In the PECS framework, users are encouraged to initiate communication by exchanging a picture of an item they want for the actual item, promoting functional communication and social skills. This method is structured in phases to gradually help users build their communication abilities, starting from simple exchanges to using sentences and more complex language.
