The short answer
No online test can diagnose ADHD. In Singapore, a diagnosis needs an assessment by a trained mental health professional, usually a psychiatrist or a clinical psychologist. For young children, the first step at KKH is a developmental paediatrician.
The free tests online are screeners. They can tell you whether an assessment is worth doing. They cannot tell you whether you have ADHD.
Where to start depends on your age, your budget and how long you are willing to wait. Each route is below.
Sources: MOH, NUHS+, KKH, IMH and the clinics' own price pages, checked October 2026. Fees and waiting times change, so confirm with the clinic before you book.
What an online ADHD test can and cannot tell you
The best-known screener is the Adult ADHD Self-Report Scale (ASRS), developed with a working group of the World Health Organization. The short version has 6 questions and is for adults aged 18 and over. The licensing page for the screener says it is not a standalone diagnostic tool, and that a diagnosis should not be made on the score alone.
Use a screener to put words to what you notice. Then take your answers, with real examples, to a psychiatrist or psychologist.
Low mood, anxiety and poor sleep can look like ADHD, and ADHD can sit alongside them. NUHS+ says a proper adult assessment includes ruling these out, which is one reason a quiz is not enough. The free Clarity Check measures mood, anxiety and wellbeing. It does not test for ADHD, but it can show whether those are part of the picture.
What an adult assessment involves
NUHS+, the National University Health System's health site, describes an adult ADHD assessment as a detailed, multi-step process. It covers your history from childhood, input from family or old school records, and checks for other causes such as anxiety, depression and sleep problems.
Before you go:
- Write down examples of how attention, organisation or restlessness affect your work and relationships
- Find old school reports if you can
- Think about someone who knew you as a child and could describe what you were like
The public route: subsidised care
Adults. Start with a GP or polyclinic doctor, who can refer you to a public psychiatrist. IMH has an adult ADHD page, and its appointment line is 6389 2200. The IMH and polyclinic referral guide walks through the steps.
MOH said in November 2025 that patients with mental health conditions can get subsidies of up to 75% at polyclinics and specialist clinics. Its reply on ADHD specifically says up to 70% at specialist clinics. Your rate depends on whether you are a Singapore Citizen or PR and on your referral, so ask when you book. Subsidised mental health services explains who qualifies.
Waiting time. MOH reported that IMH's median wait for an appointment, across all referral routes, was 25 days (parliamentary reply, 22 September 2025). That figure is more than a year old and is not specific to ADHD, and we did not find an ADHD-specific wait time.
Children up to age 6. The Child Development Programme at KKH and NUH offers subsidies of up to 70% for ADHD consultations and therapy, with a referral from a polyclinic or CHAS GP clinic (MOH, February 2024). At KKH you see a developmental paediatrician first. The psychologist's assessment usually takes 2 to 3 hours.
School-age children (7 and over). MOH says school-based support is free. Where a child needs medical care, REACH can refer them to the Child Guidance Clinic.
The private route: you book directly, and you pay in full
You can book a private psychiatrist or clinical psychologist directly, without a polyclinic referral. There is no subsidy, so the cost is higher.
Prices on clinics' own price pages for a psychologist-led adult ADHD assessment ranged from about SGD 1,850 to SGD 3,500 when we checked in October 2026. One clinic's blog says assessments start from SGD 1,150. Not every clinic dates its price page, so confirm before you book. The difference comes down to the clinic, the hours of testing and whether the written report is included.
Before you book, ask:
- How many hours the assessment takes, and over how many sessions
- Whether the written report is included in the price
- Whether a medication consultation, if you need one, is a separate fee
- Whether the clinic is a licensed medical facility, because that can affect what you are able to claim
We did not find a private psychiatrist who publishes a price for an ADHD assessment, so you will need to ask when you book.
Can you use Medisave or insurance?
Usually not for an ADHD assessment. In November 2025 MOH said mental health conditions outside the Chronic Disease Management Programme cannot be claimed with Medisave. ADHD is not on the current list of 23 conditions in that programme, and in 2016 MOH said it was not covered. Check with the clinic or MOH for the current position.
Some employer or international insurance plans do reimburse assessments. Check your policy before you book, and ask for the receipt and report format your insurer needs.
After the assessment, or while you wait
IMH lists psychotherapy and coaching for life skills, and medication in severe cases. Medication needs a prescription from a doctor.
Counselling does not diagnose ADHD or replace a psychiatrist. It can help with the day-to-day: building routines that suit how your brain works, managing emotions, easing shame and self-criticism, and treating the anxiety or low mood that often come with it. The ADHD counselling page describes how that works at Heal Counselling.
If you are not sure whether to pursue an assessment, the free 30-minute consultation is a place to talk it through. Nidhi can explain the referral options. You do not need a diagnosis or a referral to book.
