Children's ADHD Rating Scale (SNAP-IV): Parent Version
If you are concerned that your child may have ADHD, a structured rating scale can help you describe their behaviour clearly before speaking with a professional. The SNAP-IV is one of the most widely used parent and teacher rating scales for children’s ADHD symptoms. It was used in the landmark MTA Cooperative Group study, the largest clinical trial of ADHD treatments ever conducted, and maps directly onto the DSM criteria for ADHD and Oppositional Defiant Disorder (ODD).
This version is for parents. You rate your child’s behaviour across 26 statements. It takes about five minutes and gives you an immediate breakdown across three areas: inattention, hyperactivity/impulsivity, and oppositional behaviour. If you are also wondering about your own attention and focus, you may find our adult ADHD self-assessment (ASRS) useful.

Your Child's SNAP-IV Results
Subscale scores are shown as the average rating per item (0 to 3). Higher averages indicate more frequent symptoms.
Inattention
Items 1–9: attention to detail, sustaining focus, listening, organisation, forgetfulness
Hyperactivity / Impulsivity
Items 10–18: fidgeting, leaving seat, running about, talking excessively, interrupting
Oppositional Defiant
Items 19–26: temper, arguing, defiance, deliberately annoying others, anger
Supporting Your Child's Organisation and Memory
Children with ADHD traits often struggle with remembering instructions, organising tasks, and following through. Recallify helps by capturing information through voice, extracting tasks automatically, and providing structured reminders so your child (and you) can stay on top of things.
What Does the SNAP-IV Measure?
The SNAP-IV covers 26 behaviours organised into three subscales. Items 1 to 9 cover the DSM criteria for ADHD Inattention (difficulty sustaining attention, not listening, losing things, being easily distracted). Items 10 to 18 cover ADHD Hyperactivity/Impulsivity (fidgeting, running about, talking excessively, interrupting). Items 19 to 26 cover Oppositional Defiant Disorder (losing temper, arguing, defying rules, being spiteful), which is included because ODD frequently co-occurs with ADHD.
The scale was revised by Swanson, Nolan and Pelham and has been validated across numerous clinical and community samples worldwide.
How Is the SNAP-IV Scored?
Each item is rated 0 (not at all) to 3 (very much). Subscale scores are calculated as the average rating per item, giving a score between 0 and 3 for each area. The screening thresholds shown in our results are based on the [95th percentile from published parent-rating norms: 1.78 for Inattention, 1.44 for Hyperactivity/Impulsivity, and 1.88 for Oppositional Defiant. A score at or above the threshold means your child’s behaviour in that area is more frequent than 95% of same-age peers, which may warrant further assessment.
What Should I Do With These Results?
If one or more of your child’s subscale scores is above the threshold, it is worth discussing this with your GP or paediatrician. You can print or screenshot the results page to share. The SNAP-IV is not a diagnosis; it is a structured way of describing behaviour that clinicians find useful. A formal [ADHD assessment](https://recallify.ai/adhd-apps/) involves a comprehensive evaluation including developmental history, reports from school, and often direct observation. The SNAP-IV can be a helpful first step in that conversation.
How Recallify Helps Families With Organisation
Children with ADHD traits often struggle with the exact behaviours measured by the SNAP-IV: forgetting instructions, losing things, difficulty organising tasks. Recallify can help the whole family by capturing instructions and reminders through voice, automatically extracting tasks, and providing structured daily planning so that nothing falls through the cracks. Whether your child has a formal diagnosis or not, reducing the organisational burden helps everyone.
Frequently Asked Questions
Does this test diagnose my child with ADHD?
No. The SNAP-IV is a structured rating scale that helps you describe your child’s behaviour in a standardised way. ADHD can only be diagnosed by a qualified professional (paediatrician, child psychiatrist, or clinical psychologist) following a comprehensive assessment.
Can teachers also fill this in?
Yes. The SNAP-IV was designed for both parent and teacher ratings. Teacher ratings are especially useful because they provide a different context (school vs home). You could print or share the page link with your child’s teacher and compare results.
What age range is this for?
The SNAP-IV is typically used for children aged 6 to 18. It is based on DSM criteria which apply to school-age children and adolescents.
What if my child scores high on Oppositional Defiant but not on ADHD items?
ODD can occur with or without ADHD. If your child’s oppositional scores are elevated, it is still worth discussing with a professional, as ODD has its own assessment and management pathways.
