What is the Picture Exchange Communication System (PECS)?
The Picture Exchange Communication System (PECS) is a systematic way to teach a child how to communicate with someone else by handing them a picture of what they want. This program was originally designed for children with autism but can be used for other non-verbal children as well. This program is intended to provide an alternative means of communication for a child who is unable to speak with his mouth. It is not a true form of speech for the child but an alternative means that will allow him to “speak” his thoughts even if his mouth won’t cooperate.
PECS and Autism: Does it Work?
A systematic review of the research in 2008 by Tien found that PECS is effective in enhancing functional communication skills of individuals with autism spectrum disorders. That means that PECS allowed these children a means to communicate with others that they did not have before starting PECS. Even though they were not able to speak their message, they were still able to communicate functionally with the adults around them.
While the research is still unclear on whether PECS specifically will lead to better speech output (talking) for children with autism, Schlosser, R. W., & Wendt, O. looked at all of the research on augmentative and alternative communication (AAC) in general in 2008 and made this statement:
This review found no evidence that AAC intervention hinders speech production in children with autism or PDD-NOS and suggests that AAC may result in increased speech production. The authors note that the “observed gains in speech production may vary across individuals and, if they do occur, are typically small in magnitude”
As PECS is a type of augmentative and alternative communication, it falls under the term AAC.
How does PECS Work?
In order to participate in the Picture Exchange Communication System (PECS), the adult who is working with the child must be trained in how to use PECS. The program involves very specific steps that must be taught in the correct order and in the correct manner.
This article will give you an overview of the PECS process, but if you are interested in doing this with a child, you should find a training near you:

What Are the PECS Phases?
1. How to Communicate:
In the first phase of PECS, the child will learn that if they hand an adult a picture, they will get what they want in return. For this phase, there is one adult in front of the child who is holding what the child wants, and another adult behind the child guiding the child’s hand and arm to help him pick up the picture and give it to the first adult. Like I said before, this is a very specific program with very specific instructions. Each adult in this situation has an important role and has instructions on what to do. For the first phase, the child only has one picture in front of him. He’s not choosing the picture he wants from a selection, he’s just practicing the idea of handing a picture and getting what he wants.
2. Distance and Persistence:
In this phase of PECS, the child is taught to be more persistent with his communication attempts. Some of the time, the picture will be moved farther away from the child and he’ll have to go get it. In other attempts, the picture will be right next to the child but the person who is holding what he wants will start walking away. The child learns that he needs to be persistent to communicate and can’t give up.
3. Picture Discrimination:
At this point in the program, the child will be given two pictures to choose from. The child must find the picture that he wants and give that to the adult. Typically, the second picture is something that the child does not want so that he understands that he really does need to look at the pictures. Just like the other stages, this stage describes different roles for each of the two adults and shows you exactly what to do to help the child learn how to choose the correct picture.
4. Sentence Structure:
At this point, the program teaches the child how to form a simple sentence. The picture choices are placed on the front of a notebook with Velcro along with a picture that says “I want”. There is also a separate strip of Velcro that detaches from the book. The child is required to place the “I want” picture on the strip along with the picture of what they want. When the child takes that strip and hands it to the adult, the child is helped to point at each picture as the adult says the words out loud. At this point, I have seen some children with autism begin to speak the message along with the adult. That’s not the case for all children, but I definitely have seen some success with this for some children.
Attributes and Language Expansion:
Though not necessarily a true phase, there is also training on how to help a child use adjectives and other words to expand his sentences at this point.
5. Answering Questions:
This phase teaches the child how to answer the question “what do you want” using the PECS notebook and pictures. For the children that I have used with PECS, I have not often had one get this far. Typically, the child either starts talking or we have tried a different AAC system, such as a speech output device, and had success with that. That’s not to say that you can’t continue with this program, that’s just what I’ve done in the past.
This phase teaches the child to comment in response to a question. For example, you may ask “what do you see?” and the child replies with “I see ___”.
What Are the Benefits of Using PECS?
Personally, I have used PECS with many children. I find it to be especially helpful to those who are not really interested in interacting with anyone. This program teaches kiddos to initiate an interaction by handing them a picture. By using PECS, you can often take a child with no interest in other people and get them to the point where they spontaneously initiate an interaction. This can be a huge first step for children with autism or other developmental delays who were previously uninterested in communicating. Often, once they see the power of this communication, they are more open to trying other forms of communication, including speech.
What Are the Downsides of Using PECS?
PECS requires special training and two adults to complete the therapy. You cannot and should not use the materials if you haven’t been trained and it can often be difficult to find two adults to work on this at the same time. This can be especially hard if you are an SLP working in a school without a lot of other support or if you are a parent at home without another adult around most of the time. I’ve also had families tell me that it is difficult to keep the notebook and pictures around without losing or forgetting them.
Can I Use Pictures Without Doing the PECS Training?
Of course! Just because you haven’t been trained on using PECS, it doesn’t mean you can’t use pictures to support a child’s language development. Showing a child pictures of words that you are saying can increase comprehension and letting a child choose what he wants from a few pictures can be extremely helpful for a non-verbal child. Just know that if you do that without the PECS training, you are using pictures to support language development but not doing PECS.
