What is a SNAP Score?
The SNAP Score Calculator scores a simplified, SNAP-style behavior rating covering six common attention, hyperactivity, and impulsivity behaviors. It's inspired by the structure of SNAP (Swanson, Nolan, and Pelham) questionnaires commonly used as a starting reference point when discussing behavior patterns, though this simplified version is not the full validated clinical instrument.
This is a reference tool, not a diagnosis. ADHD and related conditions require evaluation by a qualified healthcare professional. See also the GAD-7 and PHQ-2 calculators for related self-screening tools.
How to use this SNAP Score calculator
- Rate each of the six behaviors from Not at all to Very much, based on recent observed frequency.
- Read the SNAP Total Score and Average Item Score instantly.
- Use the results as a starting point for a conversation with a pediatrician, psychologist, or other qualified professional — not as a standalone assessment.
Formula & Methodology
Each of the six behaviors is scored 0 (Not at all) to 3 (Very much): Total Score = Sum of all 6 item scores (range: 0-18) Average Item Score = Total Score ÷ 6 Worked example — ratings of 2, 3, 1, 2, 1, 2: Total Score = 2+3+1+2+1+2 = 11 Average Item Score = 11 ÷ 6 = 1.83 As with any behavior rating tool, results are best used to inform — not replace — a conversation with a qualified professional.
Frequently Asked Questions
A SNAP score is a behavior rating derived from a SNAP-style questionnaire (Swanson, Nolan, and Pelham), which asks a parent, teacher, or self-rater to score the frequency of common attention and hyperactivity-related behaviors. It's used as a quick reference for tracking behavior patterns, not as a diagnostic tool.
No — this is a simplified 6-item version inspired by the structure of SNAP-style questionnaires, covering common attention, hyperactivity, and impulsivity behaviors. It is not the full validated SNAP-IV instrument used in clinical ADHD assessment.
Each of the six behaviors is rated from 0 (Not at all) to 3 (Very much), and the six ratings are summed for a total score, with an average per-item score also shown for reference.
No — this calculator provides a simplified behavior rating for reference and reflection only. ADHD diagnosis requires a comprehensive clinical evaluation by a qualified healthcare professional, not a self- or parent-report questionnaire alone.
SNAP-style questionnaires are traditionally completed by parents or teachers observing a child's behavior across settings, since behavior can look different at home versus school, though this simplified version can be used for general self-reflection as well.
The six items cover attention to detail, sustained attention, following instructions, fidgeting, difficulty staying seated, and interrupting others — common behaviors referenced in attention and hyperactivity screening questionnaires.
Consider discussing the specific behaviors with a pediatrician, psychologist, or other qualified healthcare professional, who can conduct a full evaluation using validated clinical instruments and gather information from multiple settings.
The underlying SNAP-style items were originally developed with children in mind, though similar attention and hyperactivity behaviors are sometimes self-rated by adults; interpretation for adults should still involve a qualified healthcare professional.

The [GAD-7](/gad-7-calculator/) and [PHQ-2](/phq-2-calculator/) screen for anxiety and depression symptoms respectively, while this SNAP-style tool focuses on attention and hyperactivity-related behaviors — each uses a different validated questionnaire structure for a different purpose.
