Picture Exchange Communication System (PECS) is a functional means of communication intervention designed for individuals with a variety of communicative challenges. The purpose of this study was to interview a mother who implemented PECS for her 3;03 year old child with Pervasive Developmental Disorder. The interview aimed to investigate a mother's perception about the efficacy of PECS and issues related to PECS intervention. The results of the interview showed that PECS was effective in enhancing communication skills and reducing problematic behaviours. PECS also had a slight impact on speech production of the child. The issues related to PECS intervention were discussed.
