Children with autism experience difficulties with communication and interaction, and these impairments are most problematic for children who are non-verbal.

The Picture Exchange Communication System (PECS) is an intervention strategy that aims to improve communication for people with autism.

Using PECS in the family environment can be challenging in the initial stages. The specific needs of individual families should be considered and a whole family approach adopted. With appropriate support and a consistent approach, using PECS can help to improve communication and reduce challenging behaviours that might be exacerbated by the frustration of miscommunication.
