What Is the Picture Exchange Communication System (PECS)?
Understanding PECS
Overview of PECS
The Picture Exchange Communication System (PECS) is a functional communication approach developed to assist individuals with expressive communication challenges. Introduced in 1985 by Andy Bondy and Lori Frost, PECS employs a simple, engaging method using picture symbols to facilitate communication. The system allows users to convey their needs and desires by exchanging pictures, making communication both structured and enjoyable. PECS was initially implemented with preschool students diagnosed with autism at the Delaware Autism Program and has since expanded globally to support countless learners of all ages who face diverse cognitive and communication hurdles.
Importance of PECS Implementation
Implementing PECS is vital for developing decisive communication skills for children on the autism spectrum. Many individuals with autism experience expressive communication limitations, making traditional communication methods challenging. PECS provides a visual framework that can help clarify the communication process while motivating users to engage with others. Here are some key benefits of using PECS:
| Benefit | Description |
|---|---|
| Engagement | Using picture symbols makes learning to communicate fun, capturing a child's interest and encouraging participation. |
| Structure | PECS offers a clear, systematized way for individuals to express their needs, making interactions more predictable and easier to navigate. |
| Adaptability | PECS can be customized for individual preferences, allowing for personalization in communication methods. |
| Motivation | As children learn to communicate their desires through PECS, they often become more motivated to interact socially. |
Individuals may find that using picture symbols enhances their understanding of how communication functions. Successfully implementing the Picture Exchange Communication System can significantly improve the quality of life for children with autism, fostering independence, engagement, and social interaction.

Phases of PECS
The Picture Exchange Communication System (PECS) consists of a structured approach that guides individuals, particularly children diagnosed with autism, through a series of phases aimed at developing effective communication skills. This system comprises six phases, each building upon the last, to enable learners to express their needs and desires efficiently.
Phase 1: Picture Exchange
In the first phase of PECS, the focus is on teaching the learner to exchange a single picture of a desired item or action with a communicative partner. This initial step is crucial in establishing a fundamental understanding of communication as the individual learns that giving a picture will result in obtaining a specific item or action. The partner must honor the exchange as a valid request, reinforcing the connection between the picture and the desired outcome.
Phase 2: Picture Discrimination
During the second phase, learners begin to develop the ability to discriminate between different pictures. They are taught to choose from various images, selecting the one that corresponds to their needs or wants. This stage enhances decision-making skills and further reinforces the association between pictures and their meanings. It encourages them to engage more actively in communication, as they learn to make choices about what they wish to express.
Phase 3: Sentence Structure
In the third phase, the emphasis shifts to constructing simple sentences using pictures. Learners are introduced to assembling phrases, which often involves using symbols to represent common words and actions, such as "I want" followed by the picture of the desired item. This evolution in communication skills supports learners in expressing more complex needs and fosters a deeper understanding of language structure.
As children progress through these phases, they gain more confidence and competence in their ability to communicate their thoughts and desires. The systematic approach of PECS allows parents and educators to track advancements effectively and tailor instruction to meet the individual needs of each learner.

Advantages of PECS
The Picture Exchange Communication System (PECS) offers numerous benefits, particularly for children diagnosed with autism spectrum disorder. By facilitating effective communication, PECS promotes independence and encourages the development of vital skills.
Communication Independence
One of the most significant advantages of PECS is that it fosters communication independence in children. By using pictures to convey needs or thoughts, children are empowered to express themselves without relying solely on verbal communication. This can be especially vital for those who struggle with speech.
Research indicates that after training in PECS, many children experience a decrease in problem behaviors as communication becomes more effective and clear [2]. The systematic error correction procedures used in PECS further facilitate learning, ensuring children feel supported throughout the communication process.
| Benefit | Description |
|---|---|
| Enhanced Expression | Children can communicate needs and desires using pictures. |
| Reduced Frustration | Effective communication leads to fewer behavioral issues. |
| Increased Confidence | Expressing thoughts through pictures boosts self-esteem. |
Skill Development
PECS not only enhances communication skills but also promotes overall skill development. Children utilizing PECS often progress in their functional communication abilities, and some may even develop speech or transition to using speech-generating devices (SGDs) as a means of communication [2].
In addition to communication skills, studies have shown that when PECS is combined with traditional behavioral techniques, it can lead to an improvement in self-help skills. This method encourages children to engage more fully with their environment and enhances their ability to navigate daily activities.
| Skill Area | Description |
|---|---|
| Behavioral Improvement | Children often see a decrease in disruptive behaviors. |
| Self-Help Skills | Increased use of verbal or non-verbal prompts helps in everyday tasks. |
| Social Skills | Children learn to engage and communicate effectively with peers. |
The continuous progress observed through PECS emphasizes its role as a valuable tool not just for communication, but for enhancing various abilities essential for daily living. By integrating PECS into their routines, parents can support their children's growth in communication independence and skill development.

Success Stories with PECS
Case Study: 7-Year-Old with Autism
A case study involving a 7-year-old boy diagnosed with childhood autism showcased the transformative impact of the Picture Exchange Communication System (PECS). Over thirty-two sessions of intervention conducted over three months, significant improvements were noted in several target behaviors. Notably, behaviors such as repeated head turning and hand flapping showed around 60% improvement, as evaluated by both parents and clinicians.
The interventions combined PECS with traditional behavioral techniques, including contingency management and differential reinforcement. This multi-faceted approach not only reduced stereotypical behaviors but also fostered enhanced communication skills and increased independence in self-help activities. As the child learned to communicate his desires using PECS, the ability to express himself more effectively led to a notable easing of frustration and anxiety associated with poor communication [4].
| Target Behaviors | Improvement (%) |
|---|---|
| Head Turning | 60 |
| Hand Flapping | 60 |
| Communication Skills | 60 |
| Independence in Self-help | 60 |
Improvements and Maintenance
The gains made by the child were not just temporary; they were maintained during a three-month follow-up period after the intervention ended. This sustained improvement highlights the effectiveness of incorporating PECS into a child’s routine. The child demonstrated a generalized ability to communicate not only with the therapists but also in everyday situations outside the therapy room.
By teaching the child to express his experiences in different settings, the implementation of PECS proved to be a valuable tool for achieving lasting change in communication habits. The success of this case reiterates the commitment of parents and therapists in implementing effective communication systems for children diagnosed with autism.
