Sign language for nonverbal autism gives children a clear and practical way to communicate using gestures, facial expressions, and body movements when speech is limited or still developing. By starting with simple, everyday signs and using them consistently during routines, children can express their needs, reduce frustration, and build strong communication skills. Over time, sign language not only supports understanding and social interaction but can also help encourage the development of verbal speech.

Augmentative communication for autism helps children and adults express their needs, thoughts, and feelings when verbal speech is limited or still developing. By using tools like gestures, picture boards, or speech-generating devices, AAC provides a clear and reliable way to communicate in everyday situations. With early support and consistent use, it can reduce frustration, improve social interaction, and help build stronger language and communication skills over time.

The Picture Exchange Communication System (PECS) is an evidence-based, highly effective tool designed to help children with Autism Spectrum Disorder (ASD) communicate. PECS is a unique augmentative communication system that Andy Bondy, PhD, and Lori Frost, MS, CCC-SLP, developed in 1985. They first implemented it with preschool students diagnosed with autism at the Delaware Autistic Program, which played a key role in shaping and spreading the PECS approach. For parents and caregivers in Los Angeles, the PECS system provides a practical way to bridge communication gaps and helps children express their needs and desires more effectively.

If your child is nonverbal or struggles with communication, you need to understand how PECS works and how to use it in daily life. Researchers and practitioners have consistently demonstrated its effectiveness for autistic individuals and others with communication challenges. In this comprehensive guide, we walk you through the benefits of PECS, explain the six phases of implementation, and show how Nurturing Nests supports your child’s communication development every step of the way.

Key Takeaways

• The Picture Exchange Communication System (PECS) helps children with autism communicate by using pictures to express their needs and build functional communication skills.
• PECS is taught in six phases, starting with basic exchanges and progressing to complex sentence formation, enabling children to express themselves more independently.
• PECS supports children in various environments, including home, school, and the community, fostering consistent communication across real-life settings.

What is the Picture Exchange Communication System (PECS)?

PECS is a form of augmentative and alternative communication (AAC) that uses pictures to help individuals with communication disorders express their needs. Dr. Andy Bondy and Dr. Lori Frost developed PECS in the 1980s. Practitioners primarily use it with children who have autism, but it also benefits others with communication challenges. Unlike speech-generating devices or sign language, PECS relies on the exchange of pictures or symbols to communicate desires and ideas.

The pecs approach is a systematic, evidence-based method rooted in applied behavior analysis, designed to teach functional communication skills in natural environments. The PECS teaching protocol is based on B.F. Skinner’s book, Verbal Behavior, and applied behavior analysis. The system works by teaching individuals to exchange a picture of a desired item for the actual item, helping them initiate communication in a social context. It’s especially effective for children who struggle with verbal communication, offering them a means to express themselves clearly and confidently.

How PECS Helps Children with Autism Communicate

PECS offers numerous benefits for children with autism, especially for those who are non-verbal or have limited speech skills. It encourages spontaneous communication, which is often difficult for children with autism, by teaching them how to request items, express emotions, and interact socially with others.

One of the major advantages of PECS is its ability to help children initiate communication on their own. In many cases, children with autism may wait for others to start a conversation, but PECS teaches them to become active participants in communication. This skill is critical for social development and can help improve a child’s ability to interact with peers, teachers, and family members.

Furthermore, research suggests that PECS can lead to significant improvements in language development. As children master each phase of PECS, they progress toward more advanced communication, such as constructing simple sentences and responding to questions.

The 6 Phases of PECS: A Step-by-Step Guide

PECS is taught in a series of six phases, each designed to build upon the previous one. Here’s a breakdown of each phase:

1. Phase I – Teaching the Exchange of Pictures
   The first step involves teaching the child to exchange a picture of a desired item for the item itself. The child learns that by exchanging the picture, they can obtain the object, reinforcing the communication process.
2. Phase II – Expanding Sentence Structure
   In Phase II, children are taught to use more complex sentences, such as “I want,” followed by the picture of the desired item. This phase encourages the development of more advanced communication skills.
3. Phase III – Building Spontaneous Communication
   Children are encouraged to initiate communication on their own, without prompts. This phase focuses on helping children become more independent in their communication.
4. Phase IV – Teaching More Complex Sentences
   In Phase IV, children are taught to create more complex sentences by combining multiple pictures. They learn to construct phrases like “I want the red ball,” helping them express more specific needs.
5. Phase V – Responding to Questions
   This phase teaches children how to respond to questions, such as “What do you want?” This skill is important for increasing social interaction and improving conversational abilities.
6. Phase VI – Using PECS in Various Environments
   The final phase involves generalizing PECS use across different environments, such as home, school, and community settings. This phase ensures that the child can use their communication skills in a variety of real-life situations.

PECS vs. Other AAC Systems: Which is Right for Your Child?

While PECS is an effective communication tool for many children with autism, it’s important to consider other AAC systems that might also be helpful, depending on the child’s specific needs.

PECS vs Sign Language
Sign language is another form of communication used by individuals with autism. However, it requires motor coordination to form hand shapes, which may be challenging for some children. PECS, on the other hand, uses pictures, which are often easier for children to manipulate and understand.

PECS vs Speech Generating Devices (SGDs)
SGDs are electronic devices that generate speech when a user selects an image or symbol. These devices are more advanced but can be expensive and require specialized training. PECS, by contrast, is more affordable and can be implemented with minimal technology, making it a cost-effective choice for many families.

Ultimately, the choice between PECS and other AAC systems depends on your child’s needs, abilities, and family situation. A speech-language pathologist or behavior analyst can help determine the best system for your child.

How Parents Can Support PECS at Home

Parents play a critical role in helping their child succeed with PECS. By practicing consistently at home, parents can reinforce the skills learned during therapy sessions. Here are some tips for parents to support their child’s PECS progress:

• Consistency is Key: Use the same pictures and structure that the child uses in therapy sessions. This consistency helps reinforce the learning process.
• Encourage Communication: Provide opportunities for your child to use PECS throughout the day. Prompt them to ask for items using their PECS communication book or cards.
• Be Patient and Positive: Learning a new communication system takes time. Celebrate small successes and encourage your child with positive reinforcement.

The Benefits of PECS for Non-Verbal Children

PECS is particularly beneficial for non-verbal children, as it offers a way to express needs without relying on verbal communication. This is especially important for children who have difficulty speaking or who have limited speech skills. By using pictures, these children can initiate communication, ask for items, and even express emotions.

Studies show that children who use PECS often experience increased social interactions and a reduction in frustration, as they can communicate more effectively. Additionally, PECS can serve as a stepping stone to more complex forms of communication, including speech or speech-generating devices.

Conclusion

In conclusion, the Picture Exchange Communication System (PECS) offers a highly effective and accessible way for children with autism to communicate. By using pictures to express needs and desires, children can build essential communication skills that foster independence and reduce frustration. As children progress through the six phases of PECS, they develop the ability to express more complex thoughts, which ultimately improves their social interactions and overall quality of life. PECS remains a valuable tool for many families, providing a structured, yet flexible, method of communication that adapts to the unique needs of each child.

Functional communication training is an evidence-based approach that helps children replace challenging behaviors with clear, meaningful communication by teaching them how to express their needs using words, gestures, or communication tools. By identifying the purpose behind a behavior and reinforcing appropriate responses, this method builds practical communication skills, reduces frustration, and supports independence across home, school, and community settings.

Delayed echolalia is when a child repeats words or phrases after a period of time, often using language they have heard from past conversations, shows, or daily routines. While it may seem like random repetition, it is often a meaningful way for children to process language, express needs, or regulate emotions. With the right support, delayed echolalia can gradually develop into more flexible, spontaneous communication over time.

Echolalia in autism is the repetition of words or phrases, often used as a way for children to process language and communicate. While it may seem like simple repetition, it often has meaning and can support language development. With the right support, echolalia can develop into more flexible and functional speech over time.

Joint attention in autism is a foundational skill where a child shares focus with another person on an object or activity. It supports early communication, language development, and social connection. With consistent support and strategies like ABA therapy, children can strengthen joint attention and improve their ability to engage with others.

Parallel play in autism is a natural stage where children play alongside others without direct interaction. It helps build comfort, awareness, and early social skills at their own pace. With consistent support, children can gradually move toward more interactive play and stronger social connections.

Teaching turn-taking to autistic children helps them develop important social and communication skills used in everyday interactions. Turn-taking allows children to participate in conversations, games, and group activities by learning when to wait, watch, and respond. With structured strategies such as simple games, visual supports, modeling, and positive reinforcement, parents and therapists can help children gradually understand social patterns and build confidence during play and communication.

Biting is a common behavior in children with autism and is often linked to communication challenges, sensory overload, or difficulty expressing emotions. Learning how to stop biting in autism starts with understanding the triggers behind the behavior and teaching alternative ways for children to communicate and self-regulate. Strategies such as ABA therapy, positive reinforcement, sensory tools, and consistent routines can help reduce biting while supporting healthier behaviors and communication skills.
