ADHD Assessment Singapore: Where to Go, What It Costs, and How Long It Takes

Your child's teacher mentioned attention difficulties at the last parent-teacher conference. Maybe the school's SEN Officer flagged concerns. Or you've been watching your child struggle to sit still, complete homework, or follow multi-step instructions for months and you're ready to find out what's going on.

Getting an ADHD assessment in Singapore involves choosing between the public healthcare system and the private sector — and that choice affects everything from wait times to cost to what happens next at school.

The Two Assessment Pathways

Public pathway: polyclinic referral to hospital

The standard public route starts at your neighbourhood polyclinic. A GP assesses the concerns and refers your child to the Child Development Unit (CDU) at a restructured hospital — typically KK Women's and Children's Hospital (KKH), National University Hospital (NUH), or IMH.

What to expect:

• Wait time for initial appointment: 6 to 18 months from referral. The EveryChild.SG "Mind the Gap" report found that 53% of families seeking SEN assessments through the public system experienced referral loops and fragmented processes during this period.
• Assessment process: Usually involves 2-3 sessions — developmental history interview with parents, cognitive testing, behavioural observations, and sometimes school input forms. The team typically includes a developmental paediatrician and a psychologist.
• Cost: Subsidised rates for Singapore Citizens. A full psycho-educational assessment at KKH or NUH runs approximately S$200-S$500 after subsidies, depending on the complexity and number of sessions.
• Output: A formal diagnostic report with DSM-5 classification, functional recommendations, and (if applicable) medication discussion.

The main advantage is cost. The main disadvantage is time — and for a child struggling in school right now, 6-18 months of waiting means 6-18 months without targeted support.

Private pathway: direct booking

Private developmental paediatricians, child psychiatrists, and clinical psychologists accept direct bookings without a polyclinic referral. Clinics like those at Mount Elizabeth, Gleneagles, and standalone practices across the island offer ADHD assessments.

What to expect:

• Wait time: 1 to 3 months for most private clinics. Some offer appointments within weeks.
• Assessment process: Similar clinical rigour — structured interviews, standardised rating scales (e.g., Conners, SNAP-IV), cognitive testing where indicated, and behavioural observation. Some clinics complete the assessment in a single extended session; others spread it across 2-3 visits.
• Cost: S$1,600 to S$3,200 for a full psycho-educational assessment. A standalone ADHD diagnostic assessment (without full IQ and adaptive skills testing) may cost S$800-S$1,500.
• Output: Same diagnostic report format. Private reports carry equal weight with SEAB for exam accommodations and with MOE for school support requests.

What the Assessment Involves

Regardless of pathway, a thorough ADHD assessment typically includes:

Parent interview — Detailed developmental history, behaviour at home, family medical history, and current concerns. Expect 60-90 minutes.

Rating scales — Standardised questionnaires completed by parents and teachers. The school's SEN Officer or form teacher fills in the school-based ratings, which are critical for establishing that symptoms appear across settings (a DSM-5 requirement).

Cognitive testing — If a full psycho-educational assessment is conducted, this includes IQ testing (usually WISC-V) and tests of attention, processing speed, and working memory. These results help distinguish ADHD from learning disabilities or giftedness masking as inattention.

Behavioural observation — The clinician observes your child during testing and sometimes in a less structured setting. For younger children, play-based observation is common.

Medical screening — A developmental paediatrician may check for vision, hearing, thyroid, or sleep issues that can mimic ADHD symptoms.

What to Do with the Report

The assessment report is the single most important document you'll carry into every school meeting for the next several years. Here's how to use it:

Request school support. Bring the report to a meeting with the school's SEN Officer and form teacher. In mainstream MOE schools, the report gives the school a clinical basis to provide targeted support — though accommodations remain discretionary under MOE policy rather than legally mandated.

Apply for SEAB exam accommodations. If your child is approaching the PSLE or national exams, the report supports an Access Arrangements application. SEAB requires a "current profile of needs" report dated within three years of the exam. Common ADHD accommodations include extra time and separate testing rooms. Applications should go through the school's AA Coordinator at least one year before the exam.

Access Medisave. ADHD qualifies under the Chronic Disease Management Programme (CDMP). With a formal diagnosis, you can withdraw up to S$500-S$700 per year from CPF Medisave for outpatient treatment, including follow-up psychiatric consultations and medication.

Inform therapy providers. If your child is receiving occupational therapy, speech therapy, or behavioural support, the diagnostic report helps therapists calibrate their approach and may affect subsidy eligibility.

Public vs Private: Making the Call

The decision often comes down to urgency and budget.

Choose public if: Your child's difficulties are manageable in the short term, you want to minimise cost, and you can wait 6-18 months. Consider asking the polyclinic for a referral to IMH's child psychiatry service, which sometimes has shorter waits than the hospital CDUs.

Choose private if: Your child is struggling significantly right now, the school is requesting formal documentation before providing support, or a national exam is approaching and you need the report for SEAB accommodation applications within a specific timeline.

Hybrid approach: Some parents start the public referral process immediately (to secure a place in the queue), then get a private assessment in the interim if the wait becomes untenable. The private report can be used for school support and SEAB applications while the public appointment is still pending.

After Diagnosis: Understanding Your Options

An ADHD diagnosis opens doors, but it doesn't automatically unlock support. In Singapore's policy-driven system, knowing what your child is entitled to versus what requires negotiation makes a significant difference.

The Singapore Special Ed Parent Rights Compass breaks down exactly which supports are guaranteed by law, which are discretionary MOE policy, and how to escalate when the school says no — including the specific language and documentation strategies that work within Singapore's cultural context.
