Introduction to PECS
The Picture Exchange Communication System (PECS) is a communication method that utilizes pictures or symbols to help individuals with limited or no verbal communication skills express themselves effectively. Developed by Lori Frost and Andy Bondy in 1985, PECS is particularly beneficial for individuals with autism who struggle with speech.
What is PECS?
PECS is a structured system that enables individuals to initiate communication by using pictures or symbols on a series of cards. Through PECS, individuals can convey their needs, wants, feelings, and more to others. This system provides an alternative means of communication for individuals who face challenges in expressing themselves verbally.
The core principle of PECS revolves around exchanging a picture or symbol for a desired item or activity. For example, a child using PECS may hand a picture of a cookie to a communication partner in exchange for the cookie itself. This exchange helps to build and develop communication skills gradually, providing individuals with a way to communicate effectively.
Benefits of PECS
PECS offers several important benefits for individuals with communication difficulties. By using picture symbols, PECS allows individuals to initiate communication, make choices, and develop the ability to ask questions. This system promotes language development and can significantly enhance social interaction and overall quality of life for individuals with communication challenges [2].
Furthermore, PECS can be tailored to suit the specific needs and abilities of each individual. It can be introduced by professionals such as speech pathologists, occupational therapists, psychologists, or teachers who work closely with the individual. The customization aspect of PECS ensures that it can be adapted to the individual's unique circumstances and communication goals.
In the following sections, we will explore the implementation of PECS, the use of picture symbols, teaching techniques, the effectiveness of PECS supported by research and success stories, as well as considerations for implementing PECS for different age groups and adapting it to individual needs.
Implementing PECS
Implementing the Picture Exchange Communication System (PECS) involves following a specific set of phases and working closely with a communication partner. Let's explore these aspects in detail.
The Phases of PECS
PECS training consists of several phases that gradually build upon each other, teaching functional communication skills rapidly. The phases include:
- Phase 1: Teaching the Request: In this initial phase, individuals are taught to spontaneously request desired items by exchanging a picture with a communication partner. The partner immediately honors the exchange as a request. This phase focuses on motivating individuals to communicate and understand the cause-and-effect relationship between communication and their environment.
- Phase 2: Discrimination of Pictures: Once individuals have mastered requesting, they move on to discriminating between different pictures. They learn to select the correct picture representing their desired item from an array of pictures. This phase helps individuals develop the ability to make choices and communicate preferences.
- Phase 3: Sentence Structure: Building upon the previous phases, individuals learn to construct simple sentences using picture symbols. They combine different pictures to form sentences that convey more complex messages. This phase promotes the development of sentence structure and expands communication abilities.
- Advanced Phases: In the more advanced phases, individuals learn to respond to questions and comment using the PECS system. These phases further enhance their communication skills and enable them to engage in more interactive and meaningful exchanges [3].
It's important to note that following the complete PECS protocol is crucial for effective implementation, which may take several months to years to complete. While some adaptations may be made based on individual needs, it is essential to adhere to the protocol, especially in the initial stages, to ensure successful communication training for individuals with autism spectrum disorders [4].
Working with a Communication Partner
Collaboration with a communication partner is an integral part of PECS implementation. The communication partner can be a parent, teacher, therapist, or any individual involved in the individual's daily life. Here are key considerations for working effectively with a communication partner:
- Consistency: The communication partner should consistently use the PECS system and follow the established routines and procedures. This helps provide a structured and predictable communication environment.
- Prompting and Reinforcement: The communication partner should provide prompts and reinforcement during the learning process. Prompts can include verbal or physical cues to assist the individual in selecting the correct picture symbol. Reinforcement, such as praise or a preferred item, reinforces successful communication attempts.
- Responsiveness: The communication partner should respond promptly and positively to the individual's communication attempts. This encourages further engagement and motivates the individual to continue using the PECS system.
- Modeling: The communication partner can model appropriate language and sentence structure using picture symbols. This helps reinforce the learning process and provides examples for the individual to follow.
By working closely with a communication partner and following the established phases of PECS, individuals with autism spectrum disorders can develop functional communication skills and enhance their ability to interact with their environment.
Remember, PECS can be used with individuals of all ages and can be adapted to meet individual needs. It focuses on teaching language functionally and promotes initiation of communication, without requiring complex or expensive materials [3].

Using Picture Symbols in PECS
In the Picture Exchange Communication System (PECS), picture symbols play a vital role in facilitating expressive communication for individuals who struggle with verbal communication. Different types of picture symbols can be used to represent various concepts, words, and actions, making communication more understandable and accessible. It is essential to select and customize picture symbols based on individual needs and abilities.
Types of Picture Symbols
PECS utilizes various types of symbols to support communication. These symbols can include:
- Photographs: Real-life photographs of objects, people, or activities can be used as picture symbols. Photographs provide a concrete representation and can be particularly helpful for individuals who benefit from visual cues.
- Line Drawings: Colored or black and white line drawings are commonly used as picture symbols in PECS. These drawings can represent objects, actions, or concepts in a simplified and easily recognizable form.
- Tangible Symbols: Tangible symbols are physical objects that represent specific items or actions. They can be particularly useful for individuals who benefit from a more hands-on approach to communication.
The selection of the appropriate picture symbol type depends on the individual's preferences, comprehension abilities, and communication goals. It is important to consider the individual's familiarity and understanding of each symbol type to ensure effective communication.
Selecting and Customizing Picture Symbols
When implementing picture communication systems like PECS, it is crucial to select and customize picture symbols based on the individual's specific needs and goals. The use of picture symbols that exactly represent activities can make communicative messages more understandable. However, some individuals may find it challenging to communicate with pictures and identify symbolic representations. In such cases, guidance from an experienced Speech-Language Pathologist (SLP) can be invaluable for proper implementation.
Customization of picture symbols can be done to enhance their effectiveness. This may include personalizing symbols to match the individual's environment, preferences, or specific vocabulary needs. Additionally, symbols can be laminated or stored in a portable communication book for easy access and organization.
While PECS does not require the use of specific picture symbol sets, some commonly used symbols include Mayer-Johnson picture symbols. However, the selection of picture representation type and size should be based on the individual's needs and should prioritize their comprehension and ease of use.
By utilizing appropriate and customized picture symbols, individuals can effectively communicate their needs, wants, feelings, and more to others. The use of visual supports and personalized symbols in PECS can promote literacy, support learning, and aid individuals with Autism Spectrum Disorder (ASD) or other communication challenges in developing their communication skills.
Teaching Communication with PECS
The Picture Exchange Communication System (PECS) is a structured and evidence-based program that aims to teach individuals with communication challenges how to effectively communicate their wants and needs. This section will explore two key aspects of teaching communication with PECS: teaching the exchange and promoting sentence structure.
Teaching the Exchange
PECS training begins by teaching individuals to initiate spontaneous communicative interactions through the exchange of a picture for a desired item or action. This initial phase focuses on teaching the individual to give a picture of the desired item to a "communicative partner" who immediately honors the exchange as a request.
The process involves carefully selecting and customizing picture symbols that represent the desired items or actions. These symbols can be photographs, line drawings, or even objects. The individual is taught to approach the communication partner, hand them the picture symbol, and receive the requested item or action in return.
Consistency and repetition are key during this phase. With practice, individuals gradually learn to initiate and engage in communication by using the picture exchange process. This foundational skill sets the stage for further development in communication.
Promoting Sentence Structure
As individuals progress through the phases of PECS, they are taught to go beyond simple requests and develop more complex communication skills, including the ability to construct sentences. The system aims to teach discrimination of pictures and how to put them together in sentences.
In the later phases of PECS, individuals are taught to respond to questions and comment on their environment. The goal is to expand their communication abilities and provide them with the tools to express themselves effectively.
During this phase, individuals learn to combine picture symbols to form meaningful sentences. They are encouraged to use the picture symbols to express their thoughts, preferences, and experiences. The communication partner plays a crucial role in supporting and reinforcing these sentence structures.
By teaching the exchange and promoting sentence structure, PECS empowers individuals with communication challenges to express themselves, make choices, and engage in meaningful interactions. The structured and sequential nature of PECS provides a clear framework for learning, allowing individuals to progress at their own pace and build upon their communication skills.
Through the use of PECS, individuals with communication difficulties can develop a foundation for effective communication, which may indirectly support the development of speech. PECS training typically occurs during natural activities within familiar settings such as the classroom and home, promoting generalization of skills to real-life situations.
