What Is Assessed in an ADHD Evaluation

Depending on referral questions, assessment may include evaluation of:

• Sustained attention, vigilance, and response consistency

• Impulse control and inhibitory regulation

• Executive functioning, including planning, organization, working memory, and cognitive flexibility

• Processing speed and mental efficiency

• Emotional regulation and stress reactivity

• Functional impact at home, school, or work

• Co-occurring conditions, such as anxiety, learning differences, mood concerns, or autism-related features

Assessment integrates performance-based data, rating scales, history, and observation to distinguish ADHD from other causes of attentional difficulty.

Assessment Tools Used

A range of well-validated measures may be used as part of an ADHD evaluation. Test selection is individualized and may include:

• Cognitive measures, such as the Wechsler Intelligence Scales (WPPSI-IV, WISC-V, WAIS-IV/WAIS-V), with attention to working memory and processing speed

• Performance-based attention measures, such as the CPT-3

• Executive functioning tasks, including selected subtests from the D-KEFS or NEPSY-II

• Behavior and attention rating scales, completed by caregivers, teachers, or the individual (e.g., Conners-4, BRIEF-2)

• Emotional and behavioral measures, when indicated (e.g., BASC-3)

The specific tests used vary by individual and referral question; listed measures represent commonly used examples rather than a fixed battery.

A Thoughtful, Differential Approach

ADHD evaluations emphasize differential diagnosis — carefully examining whether observed challenges reflect ADHD, environmental mismatch, anxiety, learning differences, or overlapping neurodevelopmental factors. This approach supports accurate diagnosis and more effective recommendations.
