About Our ADHD Tests
What is an ADHD screening test?
It's a questionnaire that helps identify symptoms of Attention-Deficit/Hyperactivity Disorder. We use validated clinical tools—the WHO ASRS-v1.1 for adults and SNAP-IV for children—that healthcare professionals rely on. While these tests can't diagnose ADHD, they help you understand your symptoms and decide whether to seek professional evaluation.
Learn more about ADHDHow accurate are these tests?
Our tests use the same validated screening tools that healthcare professionals use worldwide. The adult test uses WHO ASRS-v1.1, and the child test uses SNAP-IV. That said, they're screening tools, not diagnostic instruments. Only a qualified healthcare professional can diagnose ADHD through comprehensive clinical evaluation.
Is my information kept private?
Yes, completely. Everything happens in your browser using local storage. We don't collect, transmit, store, or share any of your answers or results. Your information never leaves your device.
Do I need to create an account?
Nope. You can take any test without signing up, providing an email, or sharing personal information. Your results are saved locally on your device only.
Is there a cost?
No. All our ADHD screening tests are completely free—no hidden fees, no subscriptions, no catches.
Can I retake the test?
Absolutely. You can take the tests as many times as you want. This can be useful for tracking symptoms over time or after starting treatment. Just make sure to answer honestly based on how you're feeling right now for the most accurate results.
Understanding ADHD
What is ADHD?
ADHD (Attention-Deficit/Hyperactivity Disorder) is a neurodevelopmental condition that affects how your brain manages attention, impulse control, and activity levels. It shows up as persistent patterns of inattention, hyperactivity, or impulsivity that interfere with daily life. ADHD affects both kids and adults, and research shows it has a strong genetic component.
How common is ADHD?
ADHD is one of the most common neurodevelopmental conditions. About 8-10% of children and 4-5% of adults worldwide have ADHD. Interestingly, many adults with ADHD were never diagnosed as kids—they only discover it later in life when they start connecting the dots.
What are the different types of ADHD?
There are three types: Predominantly Inattentive (trouble focusing, organizing, and finishing tasks), Predominantly Hyperactive-Impulsive (restlessness, fidgeting, acting without thinking), and Combined Type (a mix of both inattention and hyperactivity-impulsivity symptoms).
Can ADHD be treated?
Yes, and treatment works well for most people. Effective approaches include medication (both stimulants and non-stimulants), behavioral therapy, educational support, ADHD coaching, and lifestyle changes. Most people with ADHD see significant improvement when they find the right combination of treatments.

Consider getting evaluated if ADHD symptoms are interfering with your work, school, relationships, or daily life. If you're struggling with organization and time management, feeling emotionally overwhelmed, or if people close to you have expressed concerns about your attention or behavior, it's worth talking to a healthcare provider.
Do adults get ADHD, or is it just for kids?
ADHD affects people of all ages. While it's often diagnosed in childhood, about 60% of kids with ADHD continue experiencing symptoms as adults. Many people aren't diagnosed until their 30s, 40s, or even later, when they finally realize their lifelong struggles with attention, organization, and impulse control have a name.
Is ADHD medication safe?
When prescribed and monitored by a qualified healthcare provider, ADHD medications are safe and effective for most people. Stimulant medications have been used for over 60 years with extensive research backing their safety. Your doctor will watch for side effects and adjust your dosage as needed. Non-stimulant options are available too if stimulants aren't right for you.
About Our ADHD Screening Tests
Which test should I take?
If you're 18 or older and wondering about your own symptoms, take the Adult ADHD Test (ASRS-v1.1). If you're a parent, teacher, or caregiver evaluating a child or teen under 18, take the Child ADHD Test (SNAP-IV).
How long does the test take?
The adult test has 18 questions and takes about 5-7 minutes. The child test has 26 questions and takes about 8-10 minutes.
Can I save my progress and come back later?
Yes. Your progress saves automatically in your browser. You can close the page and pick up where you left off later. Just note that clearing your browser data will erase your saved progress.
What do my results mean?
Your results show whether your symptoms match ADHD patterns. You'll get a score with an explanation (low, moderate, or high likelihood of ADHD symptoms) plus recommendations for next steps. Keep in mind, only a healthcare professional can officially diagnose ADHD.
Can I show my results to my doctor?
Definitely. You can print or screenshot your results to share with your doctor, psychiatrist, or therapist. Many healthcare providers actually appreciate having screening results as a starting point for evaluation.
What's the difference between screening and diagnosis?
Screening identifies potential symptoms and tells you whether further evaluation makes sense. Diagnosis requires a comprehensive assessment by a qualified healthcare professional—including clinical interviews, medical history, symptom evaluation across different settings, and ruling out other conditions that might look like ADHD.
Getting ADHD Help & Treatment
How do I find an ADHD specialist?
Start with CHADD's professional directory, check with your insurance provider, or ask your primary care doctor for a referral to a psychiatrist or psychologist who specializes in ADHD. Many people find their best providers through recommendations from others with ADHD.
Find ADHD resourcesWhat if I can't afford treatment?
There are options. Community mental health centers often have sliding-scale fees, university training clinics offer lower-cost services, and patient assistance programs can help with medication costs. CHADD runs free support groups, and some psychiatrists and therapists offer reduced rates for people without insurance.
Can I get accommodations at school or work?
Yes. Students can get accommodations through an IEP (Individualized Education Program) or 504 plan. At work, you can request reasonable accommodations under the Americans with Disabilities Act (ADA)—things like flexible schedules, written instructions, or a quiet workspace.
What if I'm in crisis?
If you're in immediate danger, call 911. For crisis support, call or text 988 for the Suicide & Crisis Lifeline, or text HOME to 741741 for the Crisis Text Line. Both are available 24/7, free, and confidential.
View complete crisis help guideHow should I prepare for my first evaluation?
Write down your symptoms and when they started, bring examples of how ADHD affects your daily life, list any medications you're taking, gather school or work records if you have them, and be ready to talk about your medical and family history. Be honest and thorough—it helps ensure an accurate diagnosis.
What if treatment isn't working?
ADHD treatment often needs adjustment. Your medication dosage might need tweaking, or you might need to try a different medication altogether. Combining medication with therapy, coaching, and lifestyle changes usually works better than medication alone. Talk openly with your healthcare provider about what's not working.
