The initial phase of PECS focuses on establishing the foundation for communication by teaching individuals to exchange a single autistic card of a desired item or action with a communication partner. This phase aims to develop basic communication skills and initiate the understanding of the exchange process.

Phase Two: Requesting Attention

Moving on to phase two, learners advance to requesting attention using picture cards. According to Special Learning, the trainer gradually moves further away from the individual, promoting the development of functional skills as the learner must actively seek and engage the attention of the communication partner.

Phase Three: Discriminating Pictures

In phase three, individuals enhance their ability to discriminate between different pictures and select the appropriate picture to convey their needs or desires. This phase strengthens visual processing skills and expands the individual's capacity to choose relevant communication symbols effectively.

Phase Four: Sentence Formation

As learners progress to phase four of the PECS system, they develop the skills required for sentence formation. Through the combination of picture symbols, individuals learn to construct simple sentences to express more complex thoughts and communicate more specific needs.

Phase Five: Advanced Communication

Advancing further, phase five focuses on enhancing advanced communication abilities. Learners are encouraged to answer questions, make observations, and expand their vocabulary to encompass a broader range of topics. This phase aims to deepen language comprehension and foster more intricate interactions.

Phase Six: Developing Complex Communication

In the final phase of the PECS system, learners are guided towards developing complex communication skills. According to Special Learning, individuals learn to respond to questions involving sensory perceptions such as "what do you see/hear/smell?" and incorporate adjectives to describe objects and experiences. This phase cultivates the ability to create more intricate and nuanced sentences, enhancing communication with caregivers, educators, and peers.

The PECS system's structured progression through these six phases aims to facilitate functional communication skills and empower individuals with autism to engage effectively with their environment. Research indicates that successful implementation of PECS can lead to improved speech development and enhanced communication capabilities, further promoting independence and social interaction.
