Getting an AAC device can feel exciting and overwhelming. A common question asked is, “How long will it take?”

Unfortunately, there is no one-size-fits-all answer. Some students show progress within a few months, while others may take a year or more to develop interest in their communication system. Progress varies based on access, support, consistency of use, and individual learning differences. 

Understanding AAC as a Language🔗

AAC is a complex language system, like spoken language. When someone receives an AAC system, they learn: 

• How to find and select buttons (a motor plan)
• What pictures and buttons mean (a symbolic system)
• When and why we communicate (a social communication framework )
• How to use and combine words in a meaningful way (a new expressive system)

Just as we would not expect a baby learning spoken language to speak in full sentences immediately, we cannot expect that from students using AAC. AAC language develops over time and in stages. 

Development does not always move in a straight line, and that’s normal. Progress may look different depending on:

• Environment
• Communication partners
• Access needs
• Language learning type  

Stages of AAC Language Development🔗

For many AAC users, here is a map of how language is learned.

1. Exposure: Hearing and Seeing the Language🔗

Before using AAC independently, students need consistent exposure. They watch others model the device, observe interactions, and begin exploring buttons. 

What this might look like: 

• Random button presses and repeating the same button
• Observing others using the device 
• Limited intentional communication 

What the user is learning: 

• Symbols and words have meaning 
• Early learning of where buttons are located 
• Communication creates responses 

Communication partner’s role: 

• Model language frequently: when you hand a student their snack, model “eat” before giving it to them.
• Respond naturally to all attempts: Exploration is a valid communication attempt!
• Avoid quizzing or pressure: Build your user’s comfort and confidence.

This stage may last weeks, months, or longer. Consistent modeling and positive experiences help build engagement with the device. 

2. Single Words🔗

After significant exposure, many students using AAC begin using single words intentionally. 

What this might look like: 

• Requests, labels, protests
• Repetition of favorite words 
• Continued exploration

What is happening: 

• Increased intentional communication 
• Early vocabulary growth 
• Finding familiar words quicker

Communication partner’s role: 

• Expand on the user’s words with models 
• Model slightly more complex language and multiple functions of communication 
• Allow the user to lead interactions 

At this stage, we still do not expect full sentences or grammatical accuracy. 

3. Word Combinations🔗

Users begin combining words, often in two- or three-word phrases. 

What this might look like: 

• 2-3 word combinations (e.g., “More goldfish”)  
• Pronoun + verb or verb + noun combinations (e.g., “I want” , “eat apple”)
• Single words and device exploration is still common 

What is happening: 

• Learning which words go together
• Expanding vocabulary 
• Combining words to express ideas 

Communication partner’s role: 

• Continue modeling phrases and sentences 
• Model different communication purposes 
• Encourage communication in many environments 

Short, repetitive, or incomplete phrases are still expected at this stage. 

4. Expanding Sentences and Communication Functions🔗

Language becomes more flexible and social. 

What this might look like: 

• Longer messages and early grammar
• Questions, comments, and responses 
• More communication across people and settings 

What is happening: 

• Developing more complex sentence structures 
• Expanding vocabulary and communication purposes 
• Greater participation in conversations 

Communication partner’s role: 

• Encourage conversations across environments 
• Allow time for processing and message creation 
• Prioritize connection over correcting language 

Growth may appear uneven, which is normal during language development. 

5. Flexible and Generative Language🔗

Communication becomes increasingly independent and creative. 

What this might look like: 

• Novel sentences 
• Storytelling and recalling experiences 
• Repairing communication breakdowns 

What is happening: 

• Easier and faster time finding words
• Flexible sentence construction 
• Deeper language understanding 

Communication partner’s role: 

• Engage in meaningful conversations 
• Respect communication preferences and autonomy 
• Support programming vocabulary when needed 

Even at this stage, supportive environments and responsive communication partners remain important for successful communication. 

Key Takeaways🔗

• Learning AAC takes time
• Progress looks different for every learner, so focus on building connections rather than comparing progress. If you feel like your student is regressing or plateauing in skills, continue modeling and using AAC. Check in with the team to see if any support strategies need to be adjusted.
• You don’t have to be an AAC expert to make a difference. Consistent, low-pressure modeling is the most important thing you can do!
• Ask your SLP if you are unsure of what or how to model. They can show you what modeling looks like on your student’s specific device.
