Vanderbilt ADHD Scoring Calculator · Parent & Teacher Forms (NICHQ)

The NICHQ Vanderbilt Assessment Scales are a set of parent and teacher rating forms that screen for ADHD and common co-occurring conditions in children ages 6–12, published by NICHQ and the American Academy of Pediatrics.

What does the NICHQ Vanderbilt measure?

The NICHQ Vanderbilt Assessment Scales are rating forms from the National Initiative for Children's Healthcare Quality (NICHQ) and the American Academy of Pediatrics (AAP) for the clinical evaluation of ADHD in children ages 6–12.

The teacher scale was first described in 1998, with the full list of DSM-IV ADHD symptoms, a screen for other disruptive behaviour disorders, anxiety and depression, and ratings of academic and classroom performance ^[3]. The parent scale followed in 2003 ^[1].

Both the parent and teacher forms assess ADHD symptom domains (inattention and hyperactivity/impulsivity) as well as comorbid conditions including oppositional defiant disorder (ODD), conduct disorder (CD), and anxiety/depression. Crucially, both forms include a performance subscale evaluating academic performance and classroom/social behaviour, which is required for a DSM-5-TR ADHD diagnosis (impairment across two settings).

How do you give the NICHQ Vanderbilt?

The scales have two initial assessment forms, the Parent Assessment Scale (55 items) and the Teacher Assessment Scale (43 items), plus follow-up forms used to monitor treatment response. Each informant completes their own form. Symptoms are rated on a 4-point frequency scale (Never / Occasionally / Often / Very Often), and the performance section is rated 1–5 (1 = excellent, 5 = problematic).

Both parent and teacher forms required

DSM-5-TR requires ADHD symptoms to be present in two or more settings. Completing both parent and teacher forms is essential for a valid ADHD evaluation. Relying on a single informant can miss or overestimate symptoms.

Vanderbilt forms and subscales

Parent Assessment Scale

• Inattention: 9 symptoms. Positive screen: ≥6 rated Often or Very Often.
• Hyperactivity/impulsivity: 9 symptoms. Positive screen: ≥6 rated Often or Very Often.
• Oppositional defiant disorder: 8 symptoms (4 or more rated Often or Very Often for an ODD screen).
• Comorbidity items: conduct, anxiety and mood symptoms.
• Performance: rated 1–5; a 4 or 5 marks impairment.

Teacher Assessment Scale

• Inattention: 9 symptoms. Positive screen: ≥6 rated Often or Very Often.
• Hyperactivity/impulsivity: 9 symptoms. Positive screen: ≥6 rated Often or Very Often.
• Disruptive behaviour items: oppositional defiant and conduct disorder symptoms.
• Performance: academic and classroom behaviour, rated 1–5; scores ≥4 indicate impairment.

How do you score and interpret the NICHQ Vanderbilt?

1. Rate each symptom item on the 4-point frequency scale: 0 = Never, 1 = Occasionally, 2 = Often, 3 = Very Often. Rate each performance item from 1 (excellent) to 5 (problematic).
2. Count, don't sum: a symptom counts toward a threshold only when it is rated 2 (Often) or 3 (Very Often).
3. Count the inattention items (items 1–9) rated Often or Very Often; 6 or more of 9 meets the inattention criterion.
4. Count the hyperactivity/impulsivity items (items 10–18) rated Often or Very Often; 6 or more of 9 meets the hyperactivity/impulsivity criterion.
5. Check performance: a positive screen also needs at least one performance item rated 4 or 5.
6. Name the presentation: the inattention criterion alone is predominantly inattentive, hyperactivity/impulsivity alone is predominantly hyperactive/impulsive, and both is combined.
7. Tally the oppositional defiant, conduct and anxiety/depression items the same way (count of items rated Often or Very Often), separately from the ADHD count; on the parent form, 4 or more of the 8 oppositional defiant items flags a possible ODD.
8. Score the parent and teacher forms separately. Both must screen positive to meet the DSM-5-TR requirement for symptoms in two or more settings.

Vanderbilt score cutoffs at a glance

Use the calculator above to check a form against these cutoffs.

Performance scale scoring (1–5)

• 1: excellent
• 2: above average
• 3: average
• 4: somewhat of a problem; clinical attention indicated
• 5: problematic; significant impairment requiring intervention

Psychometric properties

• Parent scale. In a referred sample of 243 children from a longitudinal study of ADHD diagnosis and management, the parent scale was compared with the Vanderbilt teacher scale and the Computerized Diagnostic Interview Schedule for Children-IV (parent version). Internal consistency and factor structure were acceptable and consistent with DSM-IV and other accepted ADHD measures ^[1].
• Teacher scale. In a county-wide school sample rated over two school years, the teacher scale showed four behavioural and two performance dimensions, consistent with DSM-IV criteria in both years ^[3].
• Criteria version. Both validations used DSM-IV criteria.

Limitations

• Screening, not diagnosis. A positive screen supports, but does not replace, a full clinical evaluation that rules out other explanations for symptoms.
• Informant-dependent. Ratings reflect parent and teacher perceptions, which can differ; a single informant can miss or overestimate symptoms.
• Age range. The forms are designed for children ages 6–12 and are not optimal for adolescents or adults.
• Comorbidity items are brief. The ODD, conduct, and anxiety/depression items flag possible comorbidity for follow-up; they are not full screens for those conditions.

NICHQ Vanderbilt vs ASRS: pediatric vs adult ADHD

The Vanderbilt and the ASRS serve different age groups. Many children with ADHD carry the diagnosis into adulthood, so clinics serving both children and adults need both: the Vanderbilt for children 6–12 with parent and teacher input, and the ASRS for adults who report their own symptoms.

Adolescents (13–17) are not well served by either; consider the Conners 3 or SNAP-IV.
