An ADHD assessment takes place over multiple sessions and includes the following:

Comprehensive Clinical Interview
This includes an exploration of symptom history, severity, functional impacts, and potential differential diagnoses. The assessment also covers developmental, family, and educational background. Semi-structured interview tools (e.g., the DIVA) and standardised rating scales are used to guide the diagnostic process. A medical assessment may also be encouraged as part of the overall evaluation.

Information Gathering from Third Parties
Input may be sought from relevant third parties—such as parents, teachers, or partners—to provide additional context and insight into symptoms and everyday functioning across different settings.

Feedback and Recommendations
Once all relevant information has been gathered and reviewed, a feedback session will be conducted to provide a clear explanation of the findings, including whether the criteria for ADHD are met. Tailored recommendations are offered to support ongoing needs, which may include psychological strategies, environmental adjustments, and further referrals if appropriate.
