Booking an ADHD assessment can feel like a big, slightly intimidating step.
That’s especially true if you’ve spent years wondering whether your struggles are more than just forgetfulness or being a bit disorganised. That being said, once you’ve made the decision to find out what exactly’s going on in that amazing brain of yours, it helps to know what’s coming. From paperwork to personal reflection, here are some things you can expect and how to get yourself ready without stressing out.
1. You’ll likely start with a pre-assessment form.
Before your appointment, most clinics or specialists will ask you to fill out a detailed questionnaire about your symptoms, history, and experiences. This helps them get a sense of your background before they even meet you. It might feel long or repetitive, but it’s an important part of the process.
Try to fill it out when you’re not distracted or rushing, and be as honest as possible, even if something feels small or hard to explain. These forms are designed to pick up on patterns that might not be obvious at first glance.
2. You don’t need to have everything “together” to be taken seriously.
A common worry is, “What if I seem too organised or put together for them to believe me?” However, you don’t need to be falling apart to have ADHD. Many people mask their symptoms with overcompensation, anxiety, or perfectionism.
The assessment is about what’s happening beneath the surface. If you’re struggling more than people can see, say that. It matters just as much as what’s visible from the outside.
3. You’ll be asked about your childhood.
ADHD doesn’t suddenly appear in adulthood; it’s something that starts in childhood. That’s why clinicians often ask about your early school years, home life, and behaviour as a kid. If you can, ask a parent or someone close to you what you were like growing up.
If you don’t have access to that kind of info, that’s okay. Just share what you remember, even if it’s vague. Patterns like forgetfulness, daydreaming, or struggling to follow instructions in school can all help paint the picture.
4. You’ll discuss how ADHD symptoms show up in daily life.
Expect questions like: Do you lose things a lot? Struggle to focus on conversations? Miss deadlines? They’re not just looking for textbook definitions; they want to understand how your brain works in real time.
This is where being specific helps. Instead of saying, “I get distracted easily,” give an example—like zoning out during meetings or forgetting what you walked into a room for. It’s those details that give clarity.
5. You might be asked about your emotional and mental health.

It’s not because they think your symptoms are “just anxiety”; it’s because a full picture of your mental health helps with an accurate diagnosis. Be open about how you’re feeling, even if you’re not sure whether it’s relevant.
6. Bring a list of examples or things you’ve noticed.

Don’t worry about how they sound—just jot down real experiences. Your list isn’t a test. It’s a way to help your assessor see patterns and understand what life looks like through your lens.
7. You don’t need to know all the clinical terms.

Describe things how they feel to you. Whether that’s “my brain jumps around constantly” or “I start everything and finish nothing,” your words are valid and useful. The clinician can translate it into what they need to see.
8. They’ll want to rule out other possible causes.

It doesn’t mean they don’t believe you. It just means they’re being thorough, which is actually a good sign. A good assessor won’t rush to label; they’ll take time to understand what’s really going on.
9. You may be asked to complete additional tasks or tests.

If you’re given these tasks, try not to overthink them. Just do your best. The point isn’t perfection; it’s patterns. These kinds of tests add another layer to the verbal information you share.
10. It’s okay to feel nervous or unsure.

Remember, you’re not there to convince anyone—you’re there to explore whether a diagnosis fits. Whatever the outcome, you’ve taken a proactive step toward understanding yourself better, and that’s huge.
11. The results won’t define your worth.
No matter what the outcome is—diagnosis or not—it doesn’t change your value or your struggles. Some people find that even without a formal label, they benefit from ADHD-informed strategies; others feel validated after years of feeling misunderstood.
This process is about understanding, not labelling for the sake of it. You’re allowed to feel proud of yourself just for showing up and starting the conversation. That in itself is a big deal.
12. You can prepare, but you don’t have to be perfect.
It’s great to prepare, reflect, and come in with notes, but don’t put pressure on yourself to say everything perfectly or have it all figured out. The assessor’s job is to guide the conversation and ask the right questions. You’re not doing this alone.
Your job is just to show up and be honest about your experience. Trust that your lived reality is enough. Being clear, open, and willing to reflect is what matters most, and you’ve already started that by being here.
