In the realm of communication aids for those facing cognitive, physical, and communication challenges, one system stands out for its effectiveness and worldwide acceptance - the Picture Exchange Communication System, or PECS.
The Picture Exchange Communication System (PECS®) is a communication method developed in the USA in 1985 by Andy Bondy, PhD, and Lori Frost, MS, CCC-SLP. It was initially implemented with pre-school students diagnosed with autism at the Delaware Autism Program. Since then, PECS has been adopted worldwide, aiding thousands of learners of all ages facing various cognitive, physical, and communication challenges [1].
PECS is based on B.F. Skinner's book, Verbal Behavior, and employs broad spectrum applied behavior analysis. It includes specific prompting and reinforcement strategies that encourage independent communication, systematic error correction procedures, and avoids the use of verbal prompts to build immediate initiation and prevent prompt dependency.
The PECS system begins by teaching individuals to give a single picture of a desired item or action to a "communicative partner" who then honors the exchange as a request. It progresses to teaching discrimination of pictures, putting them together in sentences, using modifiers, answering questions, and commenting.
The primary goal of the PECS communication system is to teach functional communication, promoting an understanding of how communication works in a fun and engaging way [3]. It encourages the child to initiate communication, leading to significant improvements in communication and behavioral anomalies in autism.
Research has shown that some learners using PECS also develop speech, while others may transition to a speech generating device (SGD). With over 240 research articles worldwide supporting the effectiveness of PECS, it has been recognized as an evidence-based practice.
In short, the PECS communication system can be an effective tool for enhancing communication for those with expressive communication limitations. For more information on the Picture Exchange Communication System, visit our page on picture exchange communication system.
Implementing the Picture Exchange Communication System (PECS) successfully requires a comprehensive understanding of the system and careful consideration of individual needs. This section will delve into the role of Speech Language Pathologists (SLPs) and the importance of tailoring the system to cater to individual requirements.
Implementing picture communication and identifying symbolic representations can be challenging for some individuals. The guidance of an experienced Speech Language Pathologist (SLP) can be beneficial in this process. SLPs are well-versed in the intricacies of the PECS, making them an invaluable resource as you navigate the implementation of this system.
Instructional materials are available to support trained team members in using picture communication effectively. These resources, offered by organizations such as National Autism Resources, can assist in implementing the PECS communication system more effectively.

Each individual is unique, and thus, the implementation of the PECS should be tailored to the individual's abilities and goals. This personalized approach ensures effective implementation and progress in developing communication skills.
Teaching independent expressive communication can be challenging, and motivating individuals to participate and learn is crucial. Introducing and teaching picture communication in a fun and motivating way can encourage individuals to engage in sessions and learn structured expressive communication skills.
A variety of tools, such as pecs communication cards and a pecs schedule board, can be implemented based on the individual's preferences and needs. The assessment of preferences, as well as the observation of how a person interacts with their favorite items, can help in determining the best way to modify PECS pictures for optimal accessibility.
Ultimately, the successful implementation of the PECS communication system depends on a collaborative effort between the individual, their family, and professionals such as SLPs. Through careful planning, individualized learning strategies, and ongoing support, individuals can harness the power of PECS to enhance their communication abilities.
The Picture Exchange Communication System (PECS) is a unique protocol for teaching functional communication skills to individuals who may be non-verbal or find verbal communication challenging. Developed in 1985 by Andy Bondy and Lori Frost, this approach uses symbols, communication books, specific prompting, and reinforcement. It consists of six phases, each building on the skills learned in the previous stage, to enhance communication abilities [7].
The first phase in the PECS communication system is known as the Physical Exchange. Here, individuals are taught to give a single picture of a desired item or action to a "communicative partner", who then honors the exchange by providing the requested item. This phase lays the foundation for the remaining phases, as it establishes the basic mechanics of the communication exchange and reinforces the idea that communication has direct, tangible benefits.
In the second phase, known as Expanding Spontaneity, the focus is on developing and broadening the individual's communication abilities. During this phase, the communicative partner gradually increases their distance from the individual, encouraging them to communicate more spontaneously. The individual is taught to be proactive in their communication, moving and reaching for the PECS communication book or PECS communication cards when they want to make a request.
During the Discrimination Training phase, individuals learn to differentiate between different symbols or pictures. They are taught to select and present the correct picture that corresponds to their desired item or action, from an array of options. This phase is crucial for expanding the individual's communication repertoire and providing them with the tools to express a range of wants and needs using the PECS schedule board.
Each phase of the PECS communication system is designed to gradually build on the individual's existing skills, leading to more complex and nuanced communication abilities. By working through these phases, individuals can learn to use the picture exchange communication system effectively to express their needs and desires, fostering greater independence and confidence in their communication abilities.
The Picture Exchange Communication System (PECS) has proven to be a powerful tool for individuals with autism and other communication challenges. Its effectiveness can be amplified when combined with other behavioral techniques, and long-term usage has shown impressive results.
Integrating the PECS communication system with traditional behavioral techniques can yield significant improvements in communication and behavior. A case study involving a seven-year-old child with autism demonstrated about 60% improvement in target behaviors such as repeated head turning, hand flapping, and poor communication skills after thirty-two sessions of interventions spread over three months using PECS in conjunction with behavioral techniques.
In addition to PECS, techniques such as Differential Reinforcement of Alternative Behavior (DRA), reprimand, and task direction were used to manage the child's stereotypical behaviors. This combination resulted in a significant enhancement in communication, self-help skills, and a reduction in stereotypical behaviors. The gains were maintained at the three-month follow-up, highlighting the effectiveness of this approach for managing behavioral problems in individuals with autism [4].
The Picture Exchange Communication System has shown significant long-term effectiveness for improving communication and speech outcomes for children with Autism Spectrum Disorder (ASD). Reviews have established that the PECS communication system significantly impacts communication outcomes and functional communication, such as initiating requests.
One study demonstrated the effectiveness of a PECS intervention combined with peer-mediated instruction to increase communication between children with autism and typically developing preschool children in routine social activities. The results showed positive outcomes for both groups.
The primary goal of PECS is to teach functional communication, and research has shown that some learners using PECS also develop speech. Others may transition to a speech-generating device. With more than 240 research articles from around the world supporting the effectiveness of PECS as an evidence-based practice, it is clear that the PECS communication system has a significant, long-lasting impact on individuals with various cognitive, physical, and communication challenges.

In the journey of implementing the Picture Exchange Communication System (PECS), there may arise the need to adapt or modify the system to cater to the unique needs and abilities of the learner. Such modifications, particularly regarding the PECS symbols, are vital in ensuring accessibility and successful communication.
Occupational Therapists (OTs) play a pivotal role in guiding teams through the development and modification of adapted PECS pictures. This is particularly crucial for learners who may have difficulty handling small items and various learning materials. Via assessments and observation, OTs can identify the learner's preferences and the best ways to modify PECS pictures for optimal accessibility [5].
The role of an OT is not just limited to the initial stages of implementing the PECS communication system. They also provide ongoing support, ensuring that the system continues to be effective as the learner's skills develop.
To make the PECS symbols more accessible, a common modification involves adding Velcro to the back of each picture. This creates a bit of lift and separation between the surface and the picture, making it easier for learners to pick up the symbols.
The effectiveness of such modifications should be assessed periodically. If the learner becomes independent with standard pictures, the modifications can be reduced or eliminated. Keeping a record of performance is helpful in tracking progress and making necessary adjustments.
An example of a real-world modification involved gluing a picture atop nine stacked and glued squares of craft foam. Over time, the team gradually reduced the stack height to increase the learner's independence in handling the adapted symbols.
In conclusion, adapting the PECs communication cards can significantly enhance the learner's ability to use the system effectively. By working closely with an occupational therapist and being open to adjustments, families can ensure that the PECS system remains a powerful tool for their child's communication growth.
