YOUR QUESTION. A CLEARER NEXT STEP.
What are the types or levels of ADHD?
ADHD is described by three presentations rather than fixed levels: predominantly inattentive, predominantly hyperactive-impulsive, and combined. Severity (mild to significant impact) is judged separately by a clinician who sees the whole child. Presentations can shift as a child grows, and reliable recognition happens in the school years, not in toddlers.

"What type does my child have?" is one of the first questions parents ask — and the honest, reassuring answer is that ADHD isn't a ladder of severity so much as a set of patterns.
In short
Under the WHO's ICD-11, ADHD (6A05) is described by three presentations rather than strict 'levels': a predominantly inattentive presentation, a predominantly hyperactive-impulsive presentation, and a combined presentation where both patterns appear together. A child's presentation can also shift as they grow — the picture at five is not fixed for life. Severity (how much it affects daily life) is judged separately by a clinician, not by a fixed scale you can score at home.
The three presentations, simply
- Predominantly inattentive — the child finds it hard to sustain attention, is easily distracted, may seem forgetful, loses things, or drifts off mid-task. This pattern is often quieter and so noticed later, especially in girls.
- Predominantly hyperactive-impulsive — the child is constantly on the go, fidgets, struggles to wait or stay seated, talks a great deal, and acts before thinking.
- Combined — features of both inattention and hyperactivity-impulsivity are present together. This is the most commonly recognised picture in childhood.
Clinicians describe how much these patterns affect a child's day — at home, at school, with friends — as mild, moderate or more significant. That judgement of impact is what guides support, and it is always made by a qualified professional who sees the whole child, not from a label alone.
When to seek a check
If attention, activity or impulsivity is causing real difficulty across more than one setting — say both home and school — and has done so for several months, it is worth a developmental check. ADHD is recognised reliably in the school years, not in toddlers, and a calm, structured assessment brings clarity rather than worry.
The Pinnacle way
AbilityScore® is part of Pinnacle’s developmental assessment. Diagnosis, where needed, requires an appropriately qualified healthcare professional — never from an online form or this page. Understanding which presentation fits your child is the start of a plan you can actually follow. Learn more about ADHD, explore how behaviour therapy supports attention and self-regulation, and see what the AbilityScore is and how it is established.

CONNECT THE ANSWER TO YOUR CHILD’S DAY
Something to notice. Something to discuss.
What to notice
Difficulty with attention, activity or impulsivity that shows up across more than one setting (home and school), persists for several months, and gets in the way of learning, friendships or daily routines.
In everyday life
Keep a simple two-week note of when your child finds focus hardest and what helps — short tasks, movement breaks, clear one-step instructions. These real-life observations are gold for any clinician you see.
Bring your observations and questions to your child’s professional. Choose activities that suit your child’s comfort, abilities and agreed plan.
Bring your questions to a first visitQuestions families ask
Are there official 'levels' of ADHD like Level 1, 2, 3?
No. Unlike some conditions, ADHD is not classified into numbered levels. Under WHO ICD-11 it is described by three presentations — inattentive, hyperactive-impulsive and combined — and a clinician separately judges how much it affects daily life as mild, moderate or more significant.
Can my child's type of ADHD change over time?
Yes. A child's presentation can shift with age and development. A predominantly hyperactive picture in early childhood may, for example, look more inattentive in the teen years. This is why ongoing clinician review matters more than a fixed label.
At what age can ADHD be reliably identified?
ADHD is recognised reliably in the school years, when demands on attention and self-control increase. In toddlers, high activity and short attention spans are often simply typical. A developmental check is appropriate when difficulties persist across more than one setting.
