Can autism be diagnosed for free?

Yes � in many countries, free or subsidised autism assessments are available through public health systems. In India, government hospitals including AIIMS, NIMHANS, and district hospitals provide free or heavily subsidised developmental assessments. In the UK, the NHS provides free autism assessments, though waiting times can be very long. In the USA, children can access free evaluations through Early Intervention (under age 3) and through their public school district (age 3 and above) under IDEA. In Australia, Medicare subsidises assessments through a GP-referred paediatrician. Access to free services typically comes with longer waiting times compared to private routes.

What is included in a full autism assessment?

A comprehensive autism assessment includes a detailed developmental history interview with parents (60�90 minutes), structured observation and play with the child using tools such as the ADOS-2, standardised parent questionnaires (such as the ADI-R or SCQ), and often speech, cognitive, and adaptive behaviour assessments. A written report documenting findings and recommendations is provided at the end. Some assessments also include sensory processing and occupational therapy evaluations. The total process typically takes place over 1�3 sessions.

Is a private autism diagnosis accepted by schools and services?

In most countries, yes. A diagnosis from a qualified specialist � whether from a private or public clinic � is clinically valid and should be accepted by schools and support services. In India, the RPWD Act disability certificate must be issued by a government hospital, but the diagnosis itself can be made by a private specialist whose report is then submitted to the government hospital for certification. In the UK, private diagnoses are generally accepted by schools and the EHCP process. In the USA, a private evaluation report can be used in IEP meetings. Always keep a copy of the full assessment report.

Autism Diagnosis Cost and Waiting Times: What to Expect Worldwide

When you first start trying to get your child assessed for autism, one of the first practical questions is usually: how much does this cost, and how long will I be waiting?

The answer varies enormously depending on where you live and whether you use a public or private route. This guide gives you realistic expectations for the six countries where most Nesto families live � with honest numbers and timelines, not best-case scenarios.

Quick Reference: Cost and Waiting Time by Country

Country	Public Route Cost	Public Wait	Private Cost	Private Wait
?? India	Free (govt hospital)	3�12 months	?5,000�?20,000	Days to weeks
?? UK	Free (NHS)	18 months�3+ years	�1,500��3,500	2�8 weeks
?? USA	Free (EI / school)	1�6 months	$2,000�$5,000	1�4 months
?? Australia	Subsidised (Medicare)	3�12 months	AUD 2,000�5,000	2�8 weeks
?? UAE	Subsidised (card)	1�4 months	AED 3,000�8,000	Days to weeks
?? Singapore	Subsidised (polyclinic)	6�12 months	SGD 2,000�5,000	2�6 weeks

These are approximate ranges based on 2025�2026 data. Costs and wait times change. Always verify current figures directly with providers.

Country Details

India

Public route: Government hospitals � AIIMS, NIMHANS, district hospitals � provide developmental assessments at minimal or no cost. The quality of assessment varies significantly by institution and by the specific team available. In major cities, government specialist units are often excellent. In smaller cities and rural areas, the infrastructure is thinner.

The DEIC (District Early Intervention Centre) system under RBSK provides free developmental screening and referral for children through government schools and Anganwadis. This is worth exploring if you are in a smaller city.

Private route: Developmental paediatricians in private practice in major cities can see children within a few weeks. A full assessment including ADOS-2, developmental history, and report typically costs ?8,000�?15,000 in metro cities. Paediatrician fees may be separate.

Can I use a private diagnosis for the RPWD disability certificate?

The RPWD Act disability certificate must be signed by a government hospital physician � typically from the Disability Assessment Board at a district hospital or above. However, the diagnosis can be made by a private specialist whose full assessment report is submitted to the government hospital. In practice, many families get a thorough private assessment first and then use that report at a government hospital for the certificate. The government hospital may do a brief review rather than a full reassessment.

Insurance: Very few Indian health insurance policies currently cover developmental assessments or autism therapy. This is improving slowly � some group health plans now include limited mental health coverage. Worth checking your specific policy.

United Kingdom

NHS route: Completely free, but waiting times are the most significant barrier in the UK. Average waiting times from GP referral to completed assessment are currently 18 months to 3 years in most areas, though this varies significantly by clinical commissioning group. Some areas have specialist CAMHS teams with shorter waits for young children.

You can look up your local waiting time by asking your GP or checking the NHS website for your local integrated care board. SENDIASS advisers can also tell you what typical wait times are in your area.

Private route: A full NHS-equivalent private assessment (ADOS-2, developmental history, written report) typically costs �1,500��2,500 at a reputable private clinic. Multi-professional assessments (including psychology, SLT, and OT components) may cost up to �3,500. Private diagnoses are generally accepted by schools and for the EHCP process.

Waiting while waiting: Apply for an EHCP while waiting for the assessment. You do not need a formal diagnosis to request one, and the process takes 20 weeks once started. Starting it now means it is in progress when the diagnosis comes.

United States

Early Intervention (under 3): Completely free. Contact your state's Early Intervention programme � you can self-refer, no GP needed. The evaluation must be completed within 45 days. This is one of the most accessible public early childhood services globally.

School-based evaluation (3+): Free through the public school district under IDEA. Make the request in writing. The school must complete the evaluation within 60 days (or the state's timeline).

Private evaluation: Neuropsychologists and developmental paediatricians typically charge $2,000�$5,000 for a comprehensive evaluation. Insurance coverage varies � Medicaid covers evaluations for eligible children. Private insurance may cover a developmental paediatrician visit but less commonly a full neuropsychological battery.

A private evaluation often provides a more comprehensive report than a school-based evaluation and is useful for private therapy funding and insurance prior authorisation for ABA.

Australia

Medicare route: A GP referral to a developmental paediatrician or psychiatrist allows Medicare rebates to apply. Out-of-pocket costs depend on whether the specialist bulk bills. A standard paediatric assessment with Medicare rebates applied typically costs $0�$800 out of pocket, but specialist availability varies by location.

NDIS Early Childhood: Children under 9 can access NDIS-funded early intervention without a formal diagnosis � a developmental concern may be sufficient. Contact the NDIS Early Childhood partner in your area for an access request.

Private route: Specialist paediatric psychology clinics charge AUD 2,000�5,000 for a full assessment. Private assessments have shorter waiting times and more comprehensive reports.

UAE

The UAE has a mix of government and private assessment options. Emirates Autism Society provides assessments at subsidised rates for UAE nationals and residents with People of Determination cards. Major hospital networks (Cleveland Clinic, Mediclinic, American Hospital) provide private assessments with self-referral.

The People of Determination card � obtained after a government assessment � provides subsidised therapy rates at approved centres. The card application process takes approximately 1�3 months after the initial assessment.

Singapore

Public assessments begin with a polyclinic referral to KKH, NUH, or IMH. Waiting times in the public system average 6�12 months for a full assessment. Subsidies are available for Singapore citizens and permanent residents, making public route assessments relatively affordable.

Private clinics (including specialist child development centres) can typically schedule within 2�6 weeks and charge SGD 2,000�5,000 for a comprehensive assessment. A diagnosis from a recognised specialist � public or private � is accepted by MOE, DDF, and most social service agencies.

What to Do While You Wait

Waiting for an assessment is frustrating, but the time is not wasted if you use it well.

Document everything now. Start a detailed log of what you observe � behaviours, developmental milestones reached and missed, video clips. This information is exactly what the assessment will ask for, and having it organised saves time and improves the quality of the assessment.
Start home-based support activities. You do not need a diagnosis to begin supporting your child's communication and development at home. Naturalistic play-based activities, visual schedules, and joint attention games are beneficial regardless of outcome.
Contact your child's school or nursery. Teachers can often start implementing supportive strategies before a diagnosis. In most countries, you do not need a diagnosis to request accommodations.
Connect with a parent support network. Other families who have been through the process in your specific area often have the most practical local knowledge.

A note on online screening

Structured parent observation tools � including Nesto's screening app � cannot diagnose autism, but they can provide a structured record of what you are seeing, give you a clearer picture of which behaviours warrant professional attention, and produce a document that is useful at the start of a clinical assessment. Using one while you wait is time well spent.

Start Documenting What You See Today

Nesto's free parent observation tool helps you record and organise your child's behaviours in a structured way � the same information a clinician will ask for at assessment.
