A little preparation can make your ADHD assessment far more useful. The more clearly you can describe how symptoms affect your daily life, the easier it is for the clinician to build an accurate picture. This guide explains how to prepare for your ADHD assessment, what information to gather, and what to expect, so you can get the most from your appointment.
Before you book
Once you book, you will usually be asked to complete screening questionnaires and share background information. These are not a test you can pass or fail; they simply help the clinician understand your experiences and focus the appointment. Complete them honestly and as fully as you can.
Note real, specific examples
Instead of writing only general feelings such as “I cannot focus”, note concrete examples. When does it happen, how often, and what is the consequence? Useful examples include missing bills or appointments, starting many tasks but finishing few, losing important items, struggling with time estimates, interrupting people, or needing extreme pressure to get things done. Specific examples of impact are some of the most valuable information you can bring.
Gather your childhood history
ADHD is a developmental condition, so the clinician will want to understand what you were like as a child. If you can, dig out old school reports that mention concentration, behaviour, daydreaming or inconsistent performance, and consider asking a parent or someone who knew you well what they remember. If you do not have records, do not worry; the clinician can still build the best picture from the information available.
List your health background
- Any current or past mental health conditions, such as anxiety or depression.
- Any physical health conditions and any medications or supplements you take.
- Sleep patterns, alcohol or substance use, and family history of ADHD or related conditions.
- Any previous assessments, diagnoses or support you have had.
Set up for an online appointment
If your assessment is online, find a quiet, private space where you will not be interrupted, and check your internet connection, camera and microphone in advance. Have your notes to hand, along with any documents you have gathered. See our step-by-step guide to the online assessment for a full walkthrough of what happens on the day.
Questions you might ask
It can help to prepare a few questions, such as what the assessment will involve, when you will receive your report, what the next steps are if ADHD is or is not diagnosed, and what any treatment or follow-up might cost. You can find many answers on our FAQs page.
Frequently asked questions
Do I need my old school reports?
They can be helpful because ADHD is developmental, but they are not essential. Bring what you can, and share recollections if records are not available.
What if I get nervous and forget things?
That is exactly why written notes help. Keep your examples nearby so you can refer to them during the appointment.
How long does the appointment take?
The session is typically a structured appointment of up to a couple of hours, with questionnaires completed beforehand.
