We’ve found a consistent pattern across the schools we work with. Educators and families are generally good at spotting difficulty, but less confident in identifying the underlying cause. As a result, children can find themselves on pathways that don’t quite fit — receiving support that addresses what is most visible, rather than what is most relevant. Over time, this can lead to frustration, confusion, and missed opportunities for meaningful intervention.

One of the most significant, yet often overlooked, factors in this process is masking.

Masking refers to the ways in which children learn to compensate for, or conceal, their difficulties. In the context of ADHD, this is particularly linked to executive functioning challenges — the skills that underpin planning, organisation, attention, and task management. Some children develop strategies that allow them to appear as though they are coping. They may hide their messy papers in their backpack, stay up late cramming to the last minute, or exert a disproportionate amount of effort simply to stay on track. From the outside, they may not raise immediate concern. But beneath that surface, there is often a great deal of strain.

Masking is not the absence of difficulty. It is the adaptation to it, but often an adaptation with long term drawbacks.

Much of our understanding of ADHD has historically been shaped by overt, externalised behaviours — hyperactivity, impulsivity, disruption. These are easier to observe, and therefore easier to identify. But, unfortunately, they do not represent the full picture.

Many children, particularly girls, are more likely to present with less visible traits. Their difficulties may centre around inattention, disorganisation, or internal overwhelm rather than outward disruption. They may be described as anxious, withdrawn, or lacking confidence, rather than recognised as experiencing challenges with executive functioning. Over time, they often become highly skilled at masking — working harder to compensate, and in doing so, becoming even less likely to be identified.

Cultural context also plays a role. Expectations around behaviour, attention, and compliance vary across communities and educational settings. What is considered problematic in one context may be tolerated or overlooked in another. This means that identification is not only about the child, but also about how their behaviour is interpreted through social and cultural norms.

Much of this interpretation relies on subjective evaluation — teacher observations, parent reports, behavioural checklists. These are essential tools, but they are also shaped by individual perspective, experience, and bias. Two children with similar underlying difficulties may be perceived very differently depending on how those difficulties present and how they are understood.

The consequences of this are significant. When the underlying need is not clearly identified, support often targets what is most visible. A child who is struggling with executive functioning may become anxious, and the focus shifts to managing anxiety. Another may disengage from tasks, and the response centres on motivation or behaviour. In both cases, the root cause remains unaddressed.

For the child, this can be deeply impactful. Many young people with ADHD describe a persistent sense of being “different,” without having the language to understand why. Repeated experiences of difficulty, combined with negative feedback, can erode confidence and contribute to anxiety and low mood. In some cases, they are treated for social, emotional, and mental health needs, while the underlying executive functioning challenges continue to shape their daily experience.

Masking, in this context, can be particularly damaging. It is often mistaken for coping, but in reality, it is a form of compensation. Children are not overcoming their difficulties; they are working around them, often at considerable personal cost. This can lead to exhaustion, burnout, and sudden drops in performance, particularly at key transition points where demands increase and support structures change.

If we are to better support these children, we need to complement subjective insight with more objective ways of understanding how they function.

Tools that move beyond observation and measure behaviour in real time can help provide a clearer, less biased picture. For example, our tool- EFSim (Executive Function Simulation) is a 25 minute web game designed to simulate and assess executive functioning as it happens, offering insight into how a child plans, focuses, manages tasks, and responds to distraction. Rather than asking how a child appears in a classroom, it looks at how they actually perform when completing tasks.

This kind of approach does not replace professional judgement. Instead, it strengthens it by providing an additional layer of clarity. It can help identify difficulties that may otherwise remain hidden, particularly in children who mask effectively or whose presentation does not align with traditional expectations.

Ultimately, the goal is not simply to identify ADHD. It is to understand what a child needs in order to thrive.

A diagnosis can be helpful, but it is not always immediate, and it is not, in itself, a solution. What matters most is the ability to recognise areas of difficulty early and respond with targeted, practical support. This requires a shift away from a purely diagnosis-led model towards a more needs-based approach — one that focuses on the individual, rather than the label.

If we continue to rely solely on subjective evaluation, we risk continuing to miss those who do not fit the expected profile. But by combining professional insight with more objective tools, we create an opportunity to see beyond behaviour, reduce bias, and support children more effectively.

Because in the end, it is not the label that determines a child’s outcome. It is whether we understand them well enough to help them become their best self.
