This quiz is a starting point — guiding you toward a professional evaluation that can change your life.

Online ADHD screening helps adults recognize symptoms like difficulty focusing, impulsivity, and disorganization — offering a first step toward understanding yourself better.

Why trust this ADHD test?

This screening tool was developed by The Center for ADHD, a specialized practice led by Dr. Marcy Caldwell, PsyD, a licensed clinical psychologist and nationally recognized expert in adult ADHD whose work has been featured in The New York Times, HuffPost, ADDitude, and Psychology Today. Our team focuses exclusively on the assessment and treatment of ADHD in adults.

Please note: this is a screening tool, not a diagnosis. A self-administered screening test on its own cannot diagnose ADHD — but a thorough evaluation with a licensed psychologist can confirm it.

What it takes to get a real answer

ADHD rarely travels alone, and its symptoms overlap with anxiety, depression, trauma, sleep difficulties, and learning differences. Getting an accurate answer means understanding which of these are part of your picture — and that takes a real clinical process, not a single questionnaire.

Every diagnostic evaluation we provide is conducted by a licensed psychologist trained in assessment, and includes a structured clinical interview, validated measures, and collateral input. The result is an answer you — and your doctor, and any future provider — can rely on and build a plan around. It’s also why we’re able to recognize ADHD in people it’s so often missed in: women, high achievers, and those with co-occurring conditions or learning differences.

Frequently asked questions

 A self-administered screening test on its own cannot diagnose ADHD — but a thorough evaluation with a licensed psychologist absolutely can, including when that evaluation is conducted virtually. A screener like this one is a helpful first step: it tells you whether your experiences line up with common ADHD patterns and whether a formal evaluation is worth pursuing. The diagnosis itself comes from a psychologist who examines your full history, how symptoms show up across different areas of your life, and whether anything else might better explain what you’re experiencing. In other words, it’s the clinical evaluation — not the format it’s delivered in — that makes a diagnosis valid.

A screening test asks one narrow question: “Do these symptoms show up often enough that ADHD should be on the list of possibilities?” A full evaluation asks a much bigger one: “What actually explains these symptoms, and what should we do about it?” That means examining whether the patterns began early in life, whether they appear across multiple settings, how much they genuinely interfere with your functioning, and whether anxiety, depression, trauma, sleep, learning differences, or other factors are contributing. Importantly, this kind of assessment is something psychologists are specifically trained to do — many other clinicians can treat ADHD but are not trained in formal assessment.

We offer two types, depending on your goal. A diagnostic evaluation is for people who want to understand what’s going on for them and guide treatment — it takes two sessions (an in-depth clinical interview and a feedback session), along with client and collateral rating scales and measures. A comprehensive evaluation is for people who need documentation for accommodations — on standardized testing, at school, or at work — and is more in-depth, typically four to five sessions that include clinical interview, neuropsychological measures, symptom reports, and a feedback session. If you’re not sure which fits your situation, we’ll help you decide before you commit.

Yes — this is a particular area of expertise for our team. ADHD often goes unrecognized in people who don’t fit the stereotype, including women, high achievers, people with co-occurring diagnoses or learning differences, Black clients, and members of the LGBTQIA+ community. In these cases symptoms are frequently masked, misattributed, or mistaken for anxiety, depression, or “just being disorganized.” Because we focus exclusively on ADHD in adults and are trained to recognize how it presents across different identities and life experiences, we’re able to identify it where more general evaluations often miss it.

Because of everything that goes into reaching a diagnosis you can act on. A diagnostic evaluation with us is conducted by a licensed psychologist and includes a clinical interview, validated measures, collateral reports, and a careful look at whether something other than ADHD might explain your symptoms. That process is what allows us to give you a clear, accurate answer — one that holds up for treatment, medication, and care. You’re not paying for a label; you’re paying for clarity you can trust and a path forward.
