Friendship by proximity only
They may name "friends" from preschool, but the relationships live in shared space, not shared play — no seeking each other out, no games invented together, no one asked for at home.

Autism Test for 4 Year Olds
Four is the threshold year — the last stretch before school, and the age when questions that have hovered since toddlerhood tend to demand an answer. This free 20-question screening asks what matters at four: friendships and joining in, back-and-forth conversation, flexibility, big reactions and sensory needs.
If you are here, something has probably been accumulating: a preschool comment, a birthday party where the difference was suddenly visible, a nagging comparison with siblings or cousins. Four is a genuinely good age to screen — old enough for clear signals, young enough to have support shaped before school starts. This screening is a structured guide, not a diagnosis.
Begin the 20-question screeningWhat to look for
What to look for at age four
By four, social expectations are rich: cooperative pretend play, real friendships, negotiation and conversation. These are the age-four patterns this screening asks about.
The interview-style conversation
At four, most children chat — ask, answer, comment, return. A four year old whose talk is monologues on a favourite subject, scripts, or single-word replies is conversing differently.
Group activities as endurance
Circle time, party games, singing in a group — activities that read as fun to most four year olds read as noise, unpredictability and demand to some autistic children, and produce escape or meltdown.
Rules as anchors
Deep investment in things happening the "right" way — game rules, daily sequences, who sits where — and distress wildly out of scale when they don’t.
Big feelings without a bridge
Meltdowns that arrive with little warning and take a long time to pass, especially at transitions or after busy days — regulation lagging visibly behind same-age peers.
Skills in striking peaks and valleys
Reading at four but unable to manage the playground; encyclopaedic dinosaur knowledge but no answer to "what did you do today?" — the uneven profile that so often marks autistic development.

Four occupies a particular place in the autism journey: it is the age at which "let’s wait and see" runs out of road. School is coming — with its thirty-child classrooms, sensory intensity and all-day social demand — and every question that was softened by "they’re still little" gets asked sharply by the school environment instead. Screening at four is how parents choose the gentler examiner.
It is also an age where screening is highly informative. By four, cooperative play, reciprocal conversation and flexible imagination are established in typical development, so this screening can ask twenty questions across the full childhood trait picture: social communication, friendship quality, rigidity and routines, sensory processing, and emotional regulation. The uneven profile — remarkable strengths beside unexpected struggles — becomes particularly legible at this age.
A notable result at four is an action list with a deadline that works in your favour. A GP referral made now can mean assessment underway — sometimes complete — before the first school bell, and it entitles you to raise support with the school before problems arrive rather than after. Meanwhile, document everything: the Nomi app turns daily observations of triggers, meltdowns and sensory patterns into exactly the structured record that assessments, and later schools, act on. Children do best when the adults around them understand how they work — and at four, there is still a full year to build that understanding before it is tested.
FAQ
Common questions
Should I get my four year old assessed before school starts?
If screening indicates notable traits — yes, start now. Referral-to-assessment commonly takes a year or more, so beginning at four gives you a realistic chance of answers, and support plans, by the start of school. Even an in-progress referral strengthens every conversation you have with the school.
Why didn’t anyone notice earlier if my child is autistic?
Because demands were lower. A verbal, affectionate child with subtle traits can meet every toddler milestone while the differences live in quality — how they play, converse and handle change — which only becomes visible against the richer social expectations of ages three to five. Later noticing is the norm, not a failure.
My four year old is very affectionate. Doesn’t that rule out autism?
No — the cold, unaffectionate stereotype is simply wrong. Many autistic children are deeply affectionate, often intensely so with trusted people, on their own terms and timing. Affection with family says nothing about how they manage peers, groups, change and sensory load — which is what screening assesses.
What will school actually do differently if we know?
Concretely: preparation visits, a keyed-in teacher, sensory accommodations (seating, quiet space, warning before transitions), and a pathway to formal support plans where needed. Schools respond to documentation — a screening result, referral in progress and your written observations move things that vague concern cannot.
Is this test different from the toddler one?
Yes. At four, your child takes the childhood version — twenty questions weighted toward friendships, conversation, flexibility and regulation, the areas where age-four development is informative — rather than the toddler screening’s focus on pointing, first words and early pretend play.
