Alongside, never inside
At nursery they orbit the other children — same sandpit, same room — without joining the game. Parallel play is normal at two; by three, most children are negotiating shared pretend worlds.

Autism Test for 3 Year Olds
Three is the age when the social world arrives — preschool, playdates, group games — and with it, the age many parents first clearly see their child standing apart from it. This free 16-question screening asks about the signs that matter at three: joining play, conversation, flexibility, sensory reactions and pretend worlds.
Many autistic children sail under the radar until three precisely because the demands were low before. A toddler can be "independent" and "focused"; a three year old at nursery is suddenly measured against circle time, sharing and group play. If nursery raised it, or you watched a birthday party with a sinking feeling — this screening turns that moment into structure. A guide, not a diagnosis.

What stands out at age three
At three, the reference points shift from milestones to social participation. These are the age-specific patterns parents and nursery staff most often notice first.
Conversation that doesn’t volley
They may have plenty of words — even impressive ones — but exchanges run on their track: scripts from favourite shows, facts about a beloved topic, answers that don’t quite meet your question.
Scripted language
Whole phrases lifted from Bluey, Peppa or YouTube deployed in daily life — sometimes aptly, sometimes not. Echoed language at three is a well-recognised autistic language pattern.
Rigid pretend worlds — or none
Either little pretend play, or pretend play that must run exactly the same way every time, with real distress when a playmate changes the story.
The nursery report
"He’s happiest on his own", "she finds carpet time hard", "he lines up the animals every morning" — staff see thirty children daily, and their gentle observations are screening data.
Sensory battles at full strength
Clothes seams, hand dryers, food textures, hair washing — three is often the age sensory sensitivities become unmistakable, because a three year old can fight back.
Recognise several of these?
Take the free screeningScreening at three — when the social gap opens
Three is the most common age for autism concerns to crystallise, for a structural reason: it is the first age at which children are expected to do genuinely social things — join group play, follow group routines, hold reciprocal conversation — and therefore the first age at which differences in those abilities become visible against peers. A child who seemed simply "independent" at two can look unmistakably out of step at nursery at three. Nothing changed in the child; the measuring stick changed.
Screening at three has excellent properties: the key indicators are stable and visible, language patterns like scripting and echolalia are assessable, and — critically — a child referred at three can realistically be assessed and supported before starting school. The school transition is the single most demanding environmental change of early childhood, and arriving with understanding, strategies and (where needed) a support plan in place transforms it. That is the concrete payoff of acting at three rather than "seeing how school goes".
This screening asks sixteen questions calibrated to the preschool stage. If the result indicates notable traits, request a developmental referral from your GP and ask your nursery for their written observations — professionals take structured parent evidence plus nursery corroboration very seriously. Then start tracking the specifics: triggers, sensory reactions, what helps. The Nomi app was built for exactly this stage of the journey, and the record you build becomes the backbone of the assessment.
FAQ
Common questions
Is three too late for the "early" in early intervention?
Not at all — three is squarely inside the high-impact window, which research places roughly between two and five. What matters is starting the referral process now, because waiting lists consume time whether you act or not, and support that begins at four still counts as genuinely early.
My three year old talks constantly. Can they still be autistic?
Yes — fluent, even advanced speech is common in autistic children. At three the question is not vocabulary but reciprocity: does conversation volley back and forth, or run along their track? Scripts, monologues about favourite topics and literal interpretation matter more than word count.
Nursery mentioned concerns but the GP wasn’t worried. Who do I believe?
Nursery staff observe your child for hours daily against dozens of same-age peers; a GP sees a snapshot in an unfamiliar room. Both are honest — but for developmental screening, sustained observation wins. Ask nursery to write their observations down and take that, with this screening result, back to the GP to request a referral.
Will they grow out of these behaviours?
Autistic children grow and develop enormously — but autism is a neurology, not a phase, and the "grow out of it" framing costs families years. Skills change; the underlying processing style persists. Support built on understanding that style is what makes the growing genuinely easier.
Should I wait to see how school goes at four or five?
School is the hardest transition of early childhood — more children, more noise, more rules, less adult help. Screening positive at three is a reason to prepare for school with assessment and support underway, not a reason to use school as the experiment. Acting now is what makes "how school goes" go well.
