Child ADHD screening questionnaire based on the validated NICHQ Vanderbilt scale (endorsed by the AAP). Three modes: parent, teacher and combined. Not a diagnosis.
This test applies the NICHQ Vanderbilt scale — validated and endorsed by the American Academy of Pediatrics — to indicate whether your child's symptoms cross the threshold that warrants a professional evaluation. It does not compute a "probability of ADHD": it counts symptoms across two domains (inattention and hyperactivity/impulsivity) and checks whether they impair daily life.

It uses the 18 ADHD symptom items of the NICHQ Vanderbilt scale and its scoring rule. It is a validated questionnaire that the American Academy of Pediatrics (AAP) includes in its ADHD materials, and its 18 items are the DSM-5 symptoms pediatricians assess. It does not include the scale's sections on other problems (oppositional behavior, conduct, anxiety/depression), and the impact block is a shortened 5-item version.
For each of the 18 symptoms you mark how often it occurs (from "never" to "very often"). It counts as present if it is "often" or "very often". The screen is positive only if there are 6 or more of 9 symptoms in one domain (inattention or hyperactivity/impulsivity) AND they impair school performance or relationships.
ADHD is only considered when symptoms appear in more than one setting. That is why there is a tab for parents, one for the teacher, and a "Combined" tab that cross-checks both: the combined result is positive only if the parent and the teacher each mark 6 or more of 9 symptoms in the same domain and there is impact on daily life.
This is an indicative screen, not a diagnosis. A negative result does not rule out ADHD and a positive one does not confirm it. Only a healthcare professional can diagnose. Print the report and bring it to your pediatrician.
