Child ADHD Rating — SNAP-IV Parent Form
A source-based 26-item rating form for children ages 6–18
Parents or caregivers rate behaviors across three source-defined SNAP-IV subscales. Results organize observations for discussion and cannot diagnose ADHD or another condition.
What this rating form can tell you
The SNAP-IV 26-item parent form organizes observations into three raw subscale scores: inattention (items 1–9), hyperactivity/impulsivity (items 10–18), and oppositional behavior (items 19–26). Each response is scored from 0 to 3. The scores describe reported behavior and cannot diagnose ADHD or another condition.
Subscale example
If all nine inattention items are rated ‘Just a Little’ (1), the inattention raw score is 9 out of 27. The result should be considered with concrete examples and observations from more than one setting, such as home and school.

Important Notice
This parent rating form organizes observations for children ages 6–18. It is not a diagnosis. A qualified evaluation considers information from more than one setting, development, impairment, and other possible explanations.
Frequently Asked Questions
Can this test diagnose my child?
No. This is a screening tool, not a diagnostic test. Think of it as a first step to reflect on patterns and decide whether to seek a professional evaluation. Only a qualified professional can provide a full evaluation and, if appropriate, a diagnosis.
What is the SNAP-IV?
The SNAP-IV (Swanson, Nolan, and Pelham, Version IV) is a widely used parent/teacher rating scale developed by Dr. James Swanson and colleagues. It has been used in many research studies and helps capture patterns in inattention, hyperactivity, impulsivity, and related behaviors in kids and teens.
What age range is this for?
This assessment works best for ages 6-18. For younger kids (under 6), attention difficulties can be hard to separate from normal developmental behavior, so professional evaluation is especially important. For teens, some questions need age-appropriate interpretation—for example, 'runs and climbs excessively' might show up differently in adolescents than in younger kids.
Should teachers complete this too?
Teacher input can be very helpful. Kids often behave differently at school than at home, so both perspectives can give a more complete picture. If you move forward with an evaluation, teacher observations are often part of the process.
How should I use the oppositional behavior score?
Use the raw subscale score to organize which behaviors were observed and how often. This site does not assign a severity label or diagnose a condition from that score. Concrete examples from home and school are more useful for a qualified evaluation than the number alone.
