What is PECS? The Picture Exchange Communication System, Explained

If your child does not speak yet, speaks only a few words, pulls your hand to show what they want, or gets upset because you cannot understand them, you are not alone. Many parents first hear the word PECS during a speech therapy, autism therapy, or AAC discussion.

PECS, or the Picture Exchange Communication System, is a structured way to help a child communicate using pictures. It is often used with autistic children, non-verbal children, and minimally verbal children who need a reliable way to request, choose, answer, or share something before speech is fully functional.

It is important to say this clearly: PECS is not the same as a picture schedule. A picture schedule helps a child understand routines. PECS helps a child communicate with another person.

PECS stands for Picture Exchange Communication System. It is a structured augmentative and alternative communication, or AAC, method where a child learns to give a picture to a communication partner to express a message.

The official PECS source, Pyramid Educational Consultants, says PECS was developed in the USA in 1985 by Andy Bondy, PhD, and Lori Frost, MS, CCC-SLP. It begins by teaching a learner to give a single picture of a desired item or action to another person, who immediately honors that exchange as communication.

In everyday parent language, PECS means your child uses a picture to say something they cannot yet say with speech.

For example:

The point is not just showing a picture. The key is the exchange. The child gives the picture to another person to send a message.

PECS is widely used with autistic children, but it is not only for autism. It may also support children with limited speech, developmental delays, speech-motor difficulties, or other communication needs when guided by a qualified professional.

ASHA explains that AAC can support people with speech, language, reading, or writing limitations, including neurological differences such as autism. AAC may include gestures, objects, pictures, communication boards, and speech-generating devices.

PECS is usually considered when a child has a gap between what they want to communicate and what they can express. That gap can become frustrating for the child and exhausting for parents.

A child may benefit from PECS or another AAC system if they need a more reliable way to communicate across home, school, and therapy.

PECS may be useful for children who:

Aaryavart’s PECS Communication page describes PECS as support for non-verbal and minimally verbal children to ask, choose, and be understood. It also explains that PECS can become a bridge to spoken language for some children, not a replacement for speech.

Some children attend speech therapy but still cannot reliably express daily needs. In that case, PECS or another AAC method may give the child a communication route while speech and language skills continue developing.

Aaryavart specifically notes that PECS should be used alongside Speech Therapy, not as a stand-in for it. This is the right parent mindset: communication support now, speech-language development alongside it.

PECS is not just handing a child random picture cards. It follows a structured teaching protocol. Pyramid describes six PECS phases, beginning with a single-picture exchange and moving toward discrimination, sentence structure, answering questions, and commenting.

Here is the parent-friendly version.

In the first phase, the child learns the basic exchange: give a picture to another person to get something they want.

Example: the child gives a picture of bubbles, and the adult immediately gives bubbles.

The goal is to teach: “When I give this picture to someone, they understand me.”

Once the child understands the exchange, they learn to use it with different people, in different places, and across a little distance.

This matters because communication should not work only at one table with one therapist. The child should learn to find the picture, approach the person, and keep trying to communicate.

In this phase, the child learns to choose between two or more pictures.

Example: the child chooses between juice and ball. This helps the child become more specific and intentional.

The child begins building simple picture sentences, often using a sentence strip.

Example: “I want” plus “juice.”

This is where PECS starts moving from single requests toward more structured communication.

The child learns to answer questions such as, “What do you want?”

This is important because communication is not only spontaneous requesting. Children also need to respond when someone asks them something.

In later phases, the child learns to comment using phrases such as “I see,” “I hear,” or “It is.”

This helps communication move beyond requesting food or toys. The child begins sharing attention, observations, and experiences.

This is one of the biggest parent confusions. PECS, picture cards, and picture schedules may all use pictures, but they do different jobs.

The simplest way to understand it is this: PECS helps a child say something. A picture schedule helps a child understand what happens next.

In PECS, the child exchanges a picture with a communication partner. The picture is used to send a message.

Example: the child gives a picture of a biscuit to request a biscuit.

This is communication because the child is intentionally sending a message to another person.

A picture schedule shows sequence. It helps a child understand what is happening now, what comes next, and when something is finished.

Example: brush teeth, wear shoes, pack bag, go to school.

For more detail, link readers to Sarya’s Visual Schedule vs. Picture Schedule and Visual Schedule for Autism. These support routine understanding, while PECS supports communication.

Sarya is not a PECS therapy replacement. It is a visual routine and schedule support tool that helps children follow daily routines using visual cards, custom photos, voice prompts, rewards, and progress tracking.

That distinction matters. If your child needs a communication system to request, answer, or comment, work with a speech-language professional. If your child needs help with daily routines, transitions, ADL skills, or visual structure, Sarya’s autism app can support home practice.

PECS is one type of AAC, but AAC is a much bigger category.

ASHA defines AAC as clinical support that supplements or compensates for speech-language impairments. AAC can include manual signs, gestures, objects, line drawings, communication boards, letter boards, and speech-generating devices.

PECS is usually considered a low-tech or light-tech AAC system because it uses pictures, a communication book, and sentence strips.

Other AAC options may include:

ASHA also notes that AAC systems should be flexible and individualized, and a person may use multiple communication modes depending on context, audience, and communication intent.

Parents are sometimes told to “wait for speech.” But if a child is frustrated and cannot communicate basic needs, waiting without support can make daily life harder.

A speech-language assessment can help decide whether PECS, another AAC system, speech therapy, or a combination is appropriate. The goal is not to choose pictures over speech. The goal is to give the child a communication path now.

This is one of the most common parent worries. The short answer is: PECS is not designed to stop speech. It is designed to build functional communication.

Pyramid states that the primary goal of PECS is functional communication, and that some learners using PECS also develop speech, while others may transition to a speech-generating device.

Speech is important, but communication is bigger than speech.

A child needs a way to express:

When a child gets a reliable way to communicate, frustration may reduce because the child is no longer trapped without a message.

PECS uses specific prompting, reinforcement, error correction, picture selection, and phase progression. If taught incorrectly, a child may become dependent on prompts or may only use pictures in one setting.

That is why parents should work with a speech therapist, PECS-trained therapist, AAC specialist, or autism communication team. Aaryavart offers PECS Communication, Speech Therapy, and Autism Therapy support for families who need assessment-led guidance.

PECS materials are simple, but how they are used matters. The focus should be meaningful communication, not just collecting many cards.

A therapist will usually select pictures based on what motivates the child and what the child needs to communicate in daily life.

PECS cards may show:

In the beginning, pictures often represent highly preferred items because the child needs a strong reason to communicate.

A PECS communication book stores the pictures. The child learns to remove a picture and give it to the communication partner.

Pyramid describes Phase 3 as the point where pictures are placed in a PECS communication book, which is usually a binder with fastener strips where pictures are stored and removed for communication.

In later phases, the child may use a sentence strip.

Example: “I want” plus “juice.”

The sentence strip helps the child move from single-picture requests to more structured messages.

PECS can be powerful, but only when used correctly and consistently. Many families struggle because they receive picture cards without a clear teaching plan.

Avoid these mistakes:

Aaryavart’s PECS page also emphasizes family and school training, because communication that works only in one room does not solve the real-life problem.

Parents should consider a communication assessment when a child is not able to express daily needs clearly. You do not need to wait until frustration becomes severe.

PECS, AAC, and speech therapy planning should be individualized to the child’s communication level, understanding, motor abilities, sensory needs, and family environment.

Speak with a professional if your child:

Aaryavart’s Speech Therapy page includes support for speech delay, language development, autism-related communication concerns, and parent-guided home practice.

For therapy-led support, families can explore:

Aaryavart’s autism therapy page describes support through assessment, ABA-based intervention, speech therapy, occupational therapy, sensory therapy, parent training, early intervention, and autism therapy at home.

Sarya should be used honestly in this topic. It is not a PECS replacement and should not be promoted as a speech therapy substitute. Its strength is helping children understand and follow visual routines at home, school, and therapy.

For many children, communication and routine support work together. A child may use PECS or AAC to request help, while Sarya supports the routine steps around brushing, dressing, mealtime, school prep, and bedtime.

Sarya can support families by helping children:

Sarya’s autism app page describes 500+ culturally authentic visual cards, voice guidance, predictable daily routines, and custom routine steps for activities such as brushing teeth, getting dressed, and packing a bag.

You can also link to Sarya’s features page, Visual Schedule for Autism, and Visual Schedule vs. Picture Schedule for parents who need routine support, not PECS implementation.

Use this simple parent test:

Some children may benefit from both. A speech therapist can guide PECS or AAC, while Sarya can support daily routine practice.

PECS, or the Picture Exchange Communication System, is a structured way to help a child communicate using pictures. It is most often discussed for autistic, non-verbal, or minimally verbal children, but it should be chosen and taught with professional guidance.

PECS is not the same as a picture schedule. PECS helps a child communicate. A picture schedule helps a child understand routines.

If your child struggles to express needs, consider a speech-language or PECS communication assessment through Aaryavart PECS Communication or Speech Therapy. If your child needs help following daily routines, transitions, or self-care steps, Sarya can support visual structure at home.

The goal is simple: give your child a way to be understood, while continuing to build communication, confidence, and independence.

PECS is the Picture Exchange Communication System. It is a structured AAC method where an autistic child learns to give a picture to another person to communicate a request, choice, answer, or comment.

PECS stands for Picture Exchange Communication System.

PECS is one form of AAC. AAC is the broader category that includes gestures, signs, objects, picture boards, communication books, speech-generating devices, and AAC apps.

No. PECS helps a child communicate with another person by exchanging a picture. A picture schedule helps a child understand a routine or sequence of activities.

PECS may help children who are non-verbal, minimally verbal, or unable to communicate basic needs clearly. It is commonly used with autistic children, but professional assessment is important.

The six PECS phases are: how to communicate, distance and persistence, picture discrimination, sentence structure, responsive requesting, and commenting

PECS is not designed to stop speech. Its goal is functional communication. Some learners using PECS also develop speech, and others may transition to speech-generating devices.

Yes, PECS may help a non-verbal or minimally verbal child communicate needs, choices, and later more complex messages. It should be taught with trained guidance.

Parents can support PECS at home, but they should ideally learn from a speech therapist, PECS-trained professional, or AAC specialist so the system is taught correctly and consistently.

A speech therapist or trained communication professional is strongly recommended, especially if your child has autism, speech delay, apraxia, complex communication needs, or limited understanding of pictures.

PECS cards are exchanged with a person to communicate. Visual schedule cards show a routine, such as brushing, dressing, school, lunch, and bedtime.

Sarya should not be used as a replacement for PECS therapy. Sarya supports visual routines, schedules, ADL skills, voice-guided prompts, and daily practice. PECS communication should be guided by trained professionals.

Consider PECS or AAC support if your child cannot request needs, has very limited speech, gets frustrated because they are not understood, or needs a clearer way to communicate across home, school, and therapy.

No. PECS begins with requesting, but later phases can include choosing between pictures, building sentences, answering questions, and commenting.
