If you have wondered whether you would be any good at looking after an autistic child, the answer depends far less on qualifications than you might think. You do not need to be a nurse or a teacher. What you need is a plain description of what the days look like, what the NHS and the school are supposed to do, and where the help comes from. Here it is.
Please note: this is general information about fostering in England, written in September 2026, not medical advice about any individual child. Figures come from the NHS, NICE and the Department for Education and are linked where we use them. A child living with you will have their own health plan, and their social worker and doctor are the people to follow for that child.
Autism is not something that happened to a child
The NHS puts it about as simply as it can be put. Autism is “a difference in how your brain develops that affects how you see and experience the world”, and it is “something you’re born with. It’s not an illness and there is no treatment or cure, but there are ways of managing it and getting support.” The same page, reviewed in May 2026, says that nobody knows what causes autism, that it can run in families, and that it is not caused by vaccines or medicines.
Two things follow from that, and both matter to a foster carer. Nothing you do will make a child less autistic, so any approach that promises to is selling something. And nothing that was done to the child made them autistic either. Autistic people have a wide range of intelligence: the NHS notes that some autistic people have a learning disability and some have average or above average intelligence, so knowing a child is autistic tells you very little on its own about what they can do.
Is it autism, or is it what they have been through?
This is the honest question, and carers are right to ask it. A child who has just moved in may line up their shoes, refuse to look at you, eat four foods and come apart at the school gate. Any of that could be autism. Any of it could be a child who has lost everything in a fortnight. It can easily be both.
The national guideline says the same thing in clinical language. NICE guideline CG128, in the section headed “Autism diagnostic assessment for children and young people”, tells clinicians at recommendation 1.5.7 to “consider the following differential diagnoses for autism”, and the list it gives includes attachment disorders and maltreatment alongside language disorder, ADHD, anxiety and hearing impairment. In other words, the people doing the assessment are required to hold exactly the possibility you are worried about.
What this means in practice is that you should not try to settle the question yourself, and you should not let anyone else settle it too quickly in either direction. Awful early years do not make a child less autistic. Nor does behaviour you find hard to read make a child autistic on its own. Both questions belong to the autism team. If you want the background to the other half of that picture, we have written about what trauma and attachment mean in foster care.
What you might notice at home
The NHS groups the signs in younger children under three headings: how a child communicates, how they behave and play, and sensory differences. Older children show many of the same things, and may also, in the NHS wording, “have few close friends and spend more time alone” and “find it difficult to adjust to changes in routine and activities, such as when moving from primary to secondary school”.
Sensory differences are the cheapest thing to work on and the easiest to overlook. A supermarket is loud. A school jumper has a label in it. A dinner where the gravy touches the peas is a different dinner. The NHS lists difficulty describing feelings such as hunger, pain or anger among the signs, which is worth holding on to at six in the evening when a child who cannot say “I am starving” is throwing a shoe instead.
Girls are easier to miss. The NHS says plainly that “it can be harder to see some of the signs of autism in girls because of masking”, and describes copying how other children behave and play, and being quiet in situations they find difficult. A girl who is no trouble at school and falls apart the moment she gets through your front door is doing something the NHS has a word for.
Getting an assessment, and the wait that comes with it
An autism assessment in England is done by a local multidisciplinary group, which CG128 calls the autism team. Its core membership, at recommendation 1.1.3, is “a paediatrician and/or child and adolescent psychiatrist, speech and language therapist, clinical and/or educational psychologist”. The assessment itself is not a single test. Recommendation 1.5.5 requires a developmental history, a medical history including the pregnancy and birth, a physical examination, direct observation of the child, consideration of other explanations, and a written profile of “strengths, skills, impairments and needs”.
Now the part nobody enjoys. NICE recommendation 1.5.1 says: “Start the autism diagnostic assessment within 3 months of the referral to the autism team.” NHS England’s own figures, published on 13 August 2026 and covering the year to June 2026, show 294,792 people in England with an open referral for suspected autism. Of those, 256,017, which is 86.8 per cent, had been waiting longer than 13 weeks. The National Autistic Society, writing about the same release, says the average wait reaches three years in some areas.
So the realistic answer to “how long will this take” is: much longer than the guideline, and longer than the child will be living with you if it is a short-term arrangement. That is a good reason to write things down properly as you go. The assessment leans on a developmental history, and for a child in care the adults who can supply that history change. Your daily notes may be the clearest account anyone has. We have written separately about what foster carers have to write down, and this is one of the times it earns its keep.
One in three plans
The Department for Education published its Special educational needs in England release for 2025/26 on 11 June 2026. There were 538,547 pupils with an Education, Health and Care plan, and the most common primary need recorded on those plans was autistic spectrum disorder, at 33.5 per cent. Whatever else is true about the system, autism is the single biggest thing it is being asked to handle.
For a child living with you, the practical people are the school’s SENCo, who coordinates additional support inside the school, and the designated teacher, who has a specific responsibility for children in care. Ask for both by name in the first week. Ask what adjustments are already in place rather than whether the child is entitled to any, because the second question invites a no.
What helps at home
NICE guideline CG170 covers support and management for under-19s. Its section on interventions for the core features of autism opens at recommendation 1.3.1 by telling clinicians to “consider a specific social-communication intervention for the core features of autism in children and young people that includes play-based strategies with parents, carers and teachers to increase joint attention, engagement and reciprocal communication in the child or young person”. Note who is in that sentence. Parents and carers are named in the recommendation itself.
The same section is blunt about what does not work. Recommendation 1.3.2 says: “Do not use the following interventions for the management of core features of autism in children and young people: antipsychotics, antidepressants, anticonvulsants, exclusion diets (such as gluten- or casein-free diets).” If somebody tells you a gluten-free diet will change how an autistic child communicates, the national guideline disagrees with them. Any change to a child’s diet or medication goes through their doctor and their social worker anyway, never through you and a website.
The things that genuinely help at home are duller than the internet suggests. Warn about changes before they happen, in whatever form the child takes in best. Keep the route to school the same. Find out which sounds and textures are the problem and remove the ones you can. Let a child who has come apart have somewhere quiet and boring to be, and do the talking afterwards rather than during.
The fostering standards never say the word
This is worth knowing before anyone quotes the rulebook at you. We searched the full text of the Fostering Services: National Minimum Standards, the document that governs how an agency like ours has to operate. The words “autism” and “autistic” do not appear in it anywhere. Neither does “neurodiversity”. The standards were written in 2011 and have not caught up.
What they do say is still useful. Standard 25, on managing the service, requires at paragraph 25.12 that “the service has the facilities to work with children with physical, sensory and learning impairments, communication difficulties or for whom English is not their first language”, and that communications are made available in a suitable format, naming Makaton and pictures among the arrangements. Standard 4, on safeguarding, adds at 4.6 that “for foster carers who offer placements to disabled children, this includes training specifically on issues affecting disabled children”. The standards’ word “placements” there means children living with you.
So the entitlement exists even though the vocabulary does not. If a child living with you is autistic, or is being assessed, you can ask for training built around that child rather than a general course. Our training and development is meant to follow the children you are actually caring for. There is also an older piece on the site about supporting neurodiversity if you want a gentler introduction.
Your own week matters too
CG170 has a section titled “Families and carers”, and it is the part most people skip. Recommendation 1.2.1 says clinicians should “offer all families … and carers verbal and written information about their right to: short breaks and other respite care; a formal carer’s assessment of their own physical and mental health needs, and how to access these”. “Respite” in that sentence means short breaks. Recommendation 1.2.2 goes further and asks for an assessment of the carer’s own needs, including practical support and emergency plans.
Fostering an autistic child can mean broken nights, a school that keeps ringing, and a fortnight where the only thing that changed was that you got better at spotting the build-up. Ask about short break fostering before you need it rather than after. Our support for foster carers includes a supervising social worker who knows the child, and out-of-hours support when something happens at nine on a Sunday evening.
What you are paid
South Coast pays a single weekly amount for each child, combining an allowance for the child’s costs with a professional fee for your role. On our fostering payments page today those are £479.50 a week for a child aged 0 to 10 and £507.50 a week for a child aged 11 or over. Parent and child arrangements are £987 a week.
Caring for an autistic child is not automatically paid at a different rate, and we would rather say so than imply otherwise. The page does say that “other specialist placements can involve different payments depending on the needs and care required”, and invites you to “ask us to explain the proposed package, what is included and any additional expenses”. If a child needs a level of care beyond the standard arrangement, ask that question before you agree to anything, and ask what equipment and travel costs are covered.
You won’t have to do this alone
Nobody expects a foster carer to be a clinician. What an autistic child needs from the adult they live with is far more ordinary than that: somebody who notices what sets them off, tells them what is going to happen before it happens, writes it down, and keeps turning up. The specialists do the assessing. You do the living-with, which is the part that actually changes a childhood. As we put it on the rest of this site, a child isn’t just given a home, they’re given a chance.
If you are wondering whether you could do it, a conversation costs you twenty minutes and commits you to nothing. We cover Hampshire, Dorset, Sussex, Kent, Surrey, Berkshire, Wiltshire, Somerset, Bristol and the Isle of Wight.

Frequently asked questions
Do I need a diagnosis before a child moves in?
No. Plenty of children come into care with no diagnosis and are referred afterwards, and given the waiting times many will still be waiting when they move on. You will be told what is known about the child, including any assessment already underway, before you agree to care for them.
Can a foster carer refer a child for an autism assessment?
The referral normally goes through the child’s GP, school or social worker rather than straight from you, and the decision is taken with the child’s social worker and whoever holds parental responsibility. What you can do is raise it with your supervising social worker and the child’s social worker, and back it up with dated notes of what you have seen. Written observations from the person living with the child carry weight.
Will I get training in autism specifically?
Ask for it. The National Minimum Standards require training on issues affecting disabled children for carers looking after them, and we would rather build it around the child in your house than hand you a generic course. Say what you need and when you need it.
Is fostering an autistic child harder?
Different, and sometimes harder in ways that are entirely practical: more appointments, more school meetings, more thinking ahead. It is often easier in other ways, because once you understand what a child needs their world becomes more predictable for both of you. The steep part is usually the first few months, while you are still learning one particular child.
What if the child also has ADHD or a learning disability?
That is common. CG128 asks clinicians to consider coexisting conditions as part of the assessment, and ADHD, anxiety, learning disabilities, epilepsy, feeding problems and sleep difficulties are on its list. It means more people involved in the child’s care, and it is a reason to ask early what support comes with them.
