How long does it take to get an autism diagnosis in Spain? The real data

The pathway: what happens after the first concern

The pathway is not identical across Spain. It usually begins in paediatrics or primary care, followed by referral to paediatric neurology, child and adolescent mental health services or another specialist team. Early intervention services, generally for children under six, operate alongside this pathway.

Early intervention is managed by Spain's autonomous regions and does not always sit within the health system. An analysis by Confederación Autismo España found regional differences in eligibility ages, regulations, staff, frequency of sessions and continuity once a child reaches the age limit.

Access varies by autonomous community: referral routes, age limits, waiting lists and continuity after early intervention are not the same across Spain.

How long families actually wait

A survey by Autismo España of more than 400 families across 15 regions found that 19% waited less than one month between the recommendation to start early intervention and the first session. A further 38.2% waited one to three months, 24.1% waited three to six months and 10.4% waited six to twelve months. This was a family survey, not a complete national register.

Autismo España estimates that one in four children in Spain may need early intervention. This refers to developmental needs as a whole, not to the prevalence of autism.

There is no regularly published national statistic for diagnosis. Available information consists of partial data and professional accounts: in 2023, Dr Mara Parellada of the Gregorio Marañón Hospital said that five to seven years could pass in Spain between the first concerns and confirmation. This is not one waiting-list interval; it may include the time taken to recognise signs, make referrals and complete assessment. The price of a private assessment varies by provider and by the professionals and tests involved; there is no national fee of 600 euros.

During that period, the child's needs and the educational support required may change. Specific difficulties should therefore be addressed without waiting for the final report.

The bottleneck: clinical psychology

The Spanish Ombudsman's report on psychological care in the public health system recorded around 6 clinical psychologists per 100,000 inhabitants in Spain, compared with a European average of 18, using 2018 data. This figure covers public clinical psychology as a whole and cannot, on its own, determine the waiting time for an autism assessment.

What about other countries?

Countries measure different stages of the assessment pathway, so their figures cannot be treated as directly comparable waiting lists. Public data nevertheless show delays in other health systems.

• England: in March 2026, 82.7% of people with an open referral for suspected autism had been waiting at least 13 weeks for a first contact. NHS England publishes this indicator with regional breakdowns.
• United States: the ADDM monitoring network recorded a median age of 47 months for the earliest known diagnosis among autistic eight-year-olds in its 2022 data. The age varied considerably between the sites studied and does not measure a national waiting list.

What is changing

There has been some progress. In January 2025, the Spanish Government and the autonomous communities approved the first nationwide agreement to improve early intervention and reduce waiting times. The framework is intended to be implemented by 2030, with funding from the European Child Guarantee. It is too early to assess the results, but for the first time Spain has a shared framework with indicators and monitoring. Families should know that it exists and call for it to be fully implemented.

What a family can do in the meantime

There is no need to wait for a diagnosis before responding to a specific need. Preparing someone for changes, reducing sensory overload, giving clear instructions and supporting communication may help while an assessment is pending.

It is useful to record the signs observed, when they occur, the dates of appointments and the responses received. This provides concrete information without relying on memory and reduces the need to retell the entire history to every new professional.

A diagnosis received later can still help explain needs, support applications and guide care. It does not change who the person was before receiving it.
