Why Visual Supports Don’t Work 

What drawers, cupboards and fragile systems reveal about access, ownership and the life of communication supports 

Visual supports are everywhere. On classroom walls, in therapy folders, on hospital clipboards and laminated cards clipped to lanyards. They are backed by decades of research in augmentative and alternative communication, embedded in inclusive education frameworks and recommended across allied health, education and care (Beukelman & Mirenda, 2013; CAST, 2018). 

And yet many of them quietly disappear. 

They end up in drawers. 

In my years of work across classrooms, clinics and care settings, I have seen beautifully designed visuals do important work. I have also seen them quietly vanish. 

The problem is not motivation. 

We are asking fragile systems to carry long-term access. 

Before this is interpreted as criticism, please know that we are part of the systems we are reflecting on. This blog is not about pointing outward. It is about pausing, stepping back and asking better questions. We are calling ourselves in, not out. 

If visual supports are evidence-based and rights-aligned, why do they so often end up unused? 

We all agree on the why 

Across speech pathology, occupational therapy, behaviour support, education, pscyology and nursing, there is strong alignment on the purpose of visual supports. 

They support comprehension. 
They reduce cognitive load (Sweller, 2011). 
They strengthen executive functioning. 
They increase predictability. 
They improve participation. 

Visual processing research reminds us that individuals differ in how they attend to and interpret visual information (Kaldy et al., 2020). Lived experience narratives have long highlighted the power of visual thinking and structured visual information (Grandin, 2006). 

They are embedded in inclusive education principles such as Universal Design for Learning, which calls for multiple means of representation to support diverse learners (CAST, 2018). They align with disability rights frameworks that position access as a shared responsibility rather than an individual deficit (World Health Organization, 2001). 

Visual supports are not optional extras. 

They are part of how systems uphold dignity, safety and access. 

Research consistently shows they are most effective when embedded within multimodal communication that includes gesture, spoken language and responsive interaction rather than treated as standalone artefacts (Light & McNaughton, 2012). 

The question is not whether visuals work. 

The question is whether our systems allow them to keep working. 

Barrier 1: Access is uneven and fragile 

Despite endorsement across sectors, access to quality visual supports remains inconsistent. 

For many families and services, visuals are: 

The World Health Organization’s International Classification of Functioning recognises disability as emerging from the interaction between individuals and environmental barriers rather than from impairment alone (World Health Organization, 2001). 

When access relies on someone else being available, communication becomes conditional. 

Many of us have walked into cupboards full of beautifully written plans and reports that took enormous time and expertise to produce. They are neatly stacked, pulled out for reviews, but often, are rarely used in the daily moments that matter. 

When supports live in documentation rather than in practice, they become symbolic rather than functional. 

Families are not resisting visual supports. They are navigating fragmented systems that require sustained maintenance in already stretched lives. 

The issue is not commitment. 

The issue is sustainability. 

Implementation research consistently shows that evidence-based practices fail not because they are ineffective, but because systems are not designed to support ongoing use (Fixsen et al., 2005). 

Barrier 2: Ownership often sits with professionals 

Visual supports are frequently created for people rather than with them… then again this is something we are starting to see change (and this change is good!). 

This is rarely intentional. It is often driven by care, efficiency and a desire to ensure quality. Yet when visuals are designed in professional spaces, stored on clinic drives and updated only within sessions, they become something people use rather than something they own. 

Visual supports are not single tools. They are living systems that sit within relationships, routines and environments. 

Research in augmentative and alternative communication highlights the critical role of communication partners in sustaining access (Kent-Walsh & McNaughton, 2005). Communication partners are part of the environment, not separate from it. 

When individuals are involved in selecting images, shaping language and determining how supports are used across settings, engagement shifts. 

Ownership changes sustainability. 

Barrier 3: Intersectionality extends beyond representation 

Visuals are often treated as neutral. 

They are not. 

Images carry assumptions about culture, family structures, language, routines and values. Generic symbols may be efficient, but they may also require higher symbolic interpretation and fail to reflect lived experience. 

Visual attention research reminds us that individuals process visual stimuli differently (Kaldy et al., 2020). Intersectionality extends this further. It is not only about representation. It is about whose language is prioritised, whose literacy is assumed and whose ways of communicating shape the system. 

If visual supports rely on certain levels of literacy, technology access or professional mediation, they privilege some and exclude others. 

When systems do not account for these differences, the burden shifts back onto the individual to adapt. 

That is not always inclusion. 

Barrier 4: The environment is rarely asked to change 

Visual supports are often framed as tools for the individual. 

Less often are they framed as tools for the environment. 

The environment includes physical spaces, organisational structures and the people within them. 

Visual supports work best when embedded in multimodal interaction that includes gesture, shared attention and responsive pacing (Light & McNaughton, 2012). 

If visuals are introduced without changes to communication partner behaviour, documentation practices or organisational routines, they can become compensatory rather than inclusive. 

This is not about blame. Educators, clinicians and nurses operate within time pressures and systemic constraints. The question is not whether people care. 

The question is whether systems are designed to support ongoing use. 

Barriers are rarely just technical 

Barriers to participation are attitudinal, organisational and systemic (World Health Organization, 2001). 

When visual supports fail, the issue is rarely the design of the visual alone. It may reflect funding models that privilege assessment over maintenance. It may reflect documentation systems that prioritise record-keeping over daily usability. It may reflect assumptions about independence that discourage shared scaffolding. 

Understanding barriers in this broader way shifts the conversation from fixing individuals to refining environments. 

What actually works 

Research and lived experience converge on several principles: 

Visual supports rarely operate in isolation. They work best within multimodal communication systems. 

Visuals are not magic. They are tools. Their impact depends on how they are embedded, who holds them and whether systems support their ongoing relevance. 

A collective invitation 

This is not a call out. It is a call in. 

To allied health professionals, educators and nurses: your expertise matters. Your advocacy shapes inclusive practice. 

If visual supports are embedded in our rights frameworks and evidence base, the challenge is not whether we should use them. 

The challenge is whether we are willing to design systems that allow them to live where they matter most – in the hands of the people who rely on them every day. 

When visual supports are left in drawers, the issue is rarely motivation or competence. 

It is sustainability. 

And sustainability is a systems responsibility.
