The Picture Exchange Communication System (PECS) is one of the most widely used AAC systems for children with autism and other communication needs. But is it always the right fit? In this episode, we break down the strengths and weaknesses of PECS, from its affordability and research-backed increase in spontaneous requesting to its high training costs, commenting delays, and complex motor demands.

If you’re a speech-language pathologist, parent, or educator, you’ll learn when PECS is beneficial—and when another AAC system may better support communication development.

PECS highlights the importance of commenting and functional communication beyond requesting. Inside the SIS Membership, you’ll find ready-to-use literacy and movement-based activities that strengthen early commenting, social interaction, and functional communication. Plus, you’ll get a weekly Google Slides deck for parents, large groups, and teletherapy—designed to help children thrive in real-world communication.
