Visual Supports and AAC Tools: Practical Tips for Making Communication Accessible

Visual supports and AAC tools are two of the most powerful ways to make

communication clearer, more predictable, and more accessible for autistic and

neurodivergent children. When used well, they reduce anxiety, increase

independence, and open up genuine opportunities for self expression. This guide

brings together practical, classroom ready strategies for choosing, creating, and

embedding visual supports for communication and AAC in everyday routines.

Why Visual Supports and AAC Matter

Visual information stays still, lasts longer, and gives children time to process at their

own pace. For many learners—especially those who are autistic, have language

processing differences, or experience high cognitive load—spoken language alone

can be fleeting and overwhelming. AAC tools and visual supports bridge that gap by:

• Providing consistent, predictable cues

• Reducing reliance on memory

• Supporting receptive and expressive communication

• Offering alternatives when speech is difficult

• Increasing independence and reducing adult prompting

When these tools are embedded across the day, they become part of the

environment rather than an “extra”—and that’s when communication really starts to

flourish.

Choosing the Right Visual Supports for Communication

Different children benefit from different types of visuals. The key is matching the tool

to the child’s processing style, communication goals, and environment.

Object-Based Supports

Best for learners who need concrete, tactile cues.

• Use real objects or miniature versions to represent activities (e.g., a spoon for lunch, a toy bus for home time).

• Ideal for early communicators or children who struggle with symbolic understanding.

• Keep objects consistent and store them in a predictable place.

Photo or Real-Image Supports

Useful for children who recognise real-world visuals more easily than symbols.

• Take photos of actual classroom items, staff, and locations.

• Great for transitions, routines, and choice-making.

• Ensure images are clear, uncluttered, and taken from the child’s perspective.

  
  

Symbol-Based Supports

Widely used in schools and AAC systems.

• Systems like Widgit, PCS, or SymbolStix offer consistent, recognisable images.

• Symbols can be combined to build sentences, routines, and communication boards.

• Best for children who understand pictures as representations of ideas.

  
  

Written Supports

For children who read or are developing literacy.

• Pair written words with symbols to support decoding.

• Use simple, clear fonts and high contrast.

• Great for timetables, task lists, and scripts.

  
  

Practical Tips for Creating Effective Visual Supports

Keep visuals consistent

Use the same symbol set, colour coding, and layout across the environment.

Consistency reduces cognitive load and helps children generalise meaning.

Prioritise clarity

Avoid clutter. Use one symbol per concept. Keep backgrounds plain. Make sure the

image is large enough to see from a distance.

Use colour strategically

• Colour-code categories (e.g., people = yellow, places = blue).

• Use borders to group related items.

• Avoid overusing bright colours that may distract.

  
  

Make visuals durable

Laminate, mount on card, or use Velcro for easy swapping. For high-use items like

timetables or AAC boards, consider plastic wallets or wipe-clean surfaces.

Place visuals where they’re needed

A visual is only useful if it’s accessible.

• Put timetables at eye level.

• Keep communication boards within reach.

• Attach key visuals to lanyards, tables, or doors.

  
  

AAC Tools: What They Are and How to Use Them

AAC (Augmentative and Alternative Communication) includes any method that

supports or replaces speech. It ranges from simple paper-based tools to high-tech

devices.

Low-Tech AAC Tools

These are quick to create, easy to use, and ideal for classrooms.

• Core boards — A grid of high-frequency words (e.g., go, stop, want, more).

• Choice boards — Offer options for activities, snacks, or tasks.

• Communication books — Multiple pages of symbols organised by topic.

• First–Then boards — Support transitions and task completion.

• Emotion or regulation boards — Help children express how they feel and what they need.

  
  

Low-tech AAC is often the foundation for building communication confidence before

introducing high-tech systems.

High-Tech AAC Tools

These include apps and devices that generate speech.

• Tablet-based apps (e.g., Proloquo2Go, Grid, LAMP Words for Life)

• Dedicated speech-generating devices

• Eye-gaze systems for children with physical access needs

High-tech AAC offers flexibility, vocabulary growth, and independence—but it must

be personalised, taught explicitly, and used consistently across environments.

Embedding AAC Tools and Visual Supports Across the Day

The biggest impact comes from using visuals and AAC tools naturally and

frequently—not just during structured sessions.

During Transitions

• Use a visual timetable and remove or tick off items as they happen.

• Offer countdowns with number visuals or timers.

• Use First–Then boards to show what’s happening now and next.

During Play and Learning

• Model language on AAC tools while playing (“I want turn”, “go fast”, “stop”).

• Keep core boards on tables, floors, and outdoor areas.

• Use visuals to support group instructions (“sit”, “look”, “listen”, “finished”).

  
  

  During Emotional or Sensory Moments

• Provide a regulation board with options like “quiet”, “break”, “deep pressure”, “help”.

• Use visuals to label zones or sensory areas.

• Offer scripts for asking for help or expressing discomfort.

  
  

  During Routines

• Use step-by-step visuals for toileting, handwashing, lining up, or packing away.

• Keep visuals portable—lanyards, keyrings, or mini-books work well.

• Encourage independence by pointing to visuals instead of repeating verbal prompts.

  
  

Modelling: The Most Important Strategy

AAC only works when adults model it. Children need to see AAC being used in real

contexts to understand how it works.

What modelling looks like

• Pointing to symbols while speaking

• Using the child’s AAC system to comment, request, or describe

• Modelling without expecting the child to copy

• Keeping modelling natural and embedded in routines

  
  

Modelling shows children that AAC is a valid, respected form of communication—not

something they must “earn” or use only when prompted.

Troubleshooting Common Challenges

“They don’t look at the visuals.”

Keep using them. Many children process visuals peripherally. Exposure builds

familiarity.

“They only use AAC to request.”

Model commenting (“fun”, “big”, “look”), protesting (“stop”, “no”), and social language

(“hi”, “my turn”).

“They throw or avoid visuals.”

Reduce size, simplify layout, or use sturdier materials. Check sensory

needs—laminated cards can be noisy or reflective.

“Staff forget to use AAC.”

Place boards in every area, add reminders to lanyards, and build AAC into routines

(e.g., morning check-in, snack choices).

Working Collaboratively With Staff and Families

Visual supports and AAC tools work best when everyone uses them consistently.

• Share simple guides or cheat sheets for staff.

• Offer modelling sessions during class routines.

• Send home copies of key visuals.

• Keep vocabulary consistent across home and school.

• Celebrate small wins—every communication attempt matters.

  
  

Collaboration ensures the child experiences a predictable communication

environment, reducing frustration and increasing confidence.

Building a Communication-Rich Environment

A communication-rich environment is one where visuals and AAC are:

• Visible

• Accessible

• Normalised

• Used by adults

• Embedded in routines

• Personalised to the child

When communication tools are part of the fabric of the classroom, children feel

empowered to express themselves in the way that works best for them.

Final Thoughts

Visual supports and AAC tools aren’t optional extras — they’re essential communication access tools. When they’re chosen thoughtfully and used consistently, they can completely transform how children understand, engage, and connect with the world around them. The key is simple: make communication visible, predictable, and shared.
