The quarter of kids falling behind before school even starts
One in four Australian children starts school already developmentally behind — and the research telling us how to help them is silent on why the number keeps climbing.
One in four Australian children arrives at school already behind. Not behind in the sense of needing a bit of extra attention, but developmentally vulnerable: missing the self-regulation, language, and social skills that learning depends on. The gap opens before kindergarten. In many cases, it opens before a child can hold a pencil, a conversation, or a tablet.
Quality early intervention produces measurable gains — but only for children already behind
The University of Melbourne research published this month in The Conversation offers genuine grounds for optimism about what can be done once vulnerability is established. A targeted program running across three Victorian and Queensland childcare sites has produced measurable gains: an average 11.6-point increase in resilience and self-regulation scores after just one year, alongside meaningful improvements in language development and IQ. The children in the program are referred by child protection and community health professionals, and they arrive with significant exposure to family stress, trauma, and disadvantage. These are not easy cases. The gains are real.
The program works by surrounding children and families with what most of them have not had: stability, consistency, individual attention, warm food, and adults who respond rather than react. It is intensive by design because the children's needs are intensive by reality. The research makes a credible case that well-resourced, multi-disciplinary early intervention is not a luxury, but a mechanism with measurable returns on life outcomes.
So the policy argument for better-funded, higher-quality early childhood care is sound, and the evidence supports pursuing it. But good policy asks not only how to treat a condition, but how it gets produced in the first place.
The 25 per cent figure is a signal, not a baseline
The 25 per cent figure, taken on its own, raises a question the research does not address: why is developmental vulnerability at school entry so widespread, and is it getting worse? The Melbourne researchers themselves note that children entering the program in 2026 arrived with more family risk factors than the original cohort. Something is building.
Family stress and disadvantage have always existed. They cannot explain a trend. What has changed, dramatically and universally, is the screen environment in which Australian infants and toddlers are now growing up. ABS data reported here at The Bearing found that nearly three in four Australian children aged five to seventeen regularly exceed the government's own two-hour daily recreational screen time guidelines. The data covers older children, but the device saturation begins much earlier.
A child watching a screen is not making eye contact, not waiting for a response, not learning to hold ambiguity.
The research on screen exposure in infancy and early toddlerhood is not yet definitive. That needs to be said plainly. But it is no longer thin. A growing body of peer-reviewed literature associates heavy screen time in the under-twos with delays in language acquisition, reduced capacity for sustained attention, and weaker social-emotional development, the same domains flagged in developmental vulnerability assessments. The mechanism proposed is not complicated: screens are compelling precisely because they are designed to be. They interrupt the kind of slow, reciprocal, face-to-face interaction through which language and emotional regulation are actually built. A child watching a screen is not making eye contact, not waiting for a response, not learning to hold ambiguity.
None of this means screens are the sole driver, or that every parent handing a toddler a tablet is causing harm. Poverty, housing instability, parental mental health, and access to quality care all matter, and in many cases matter more. But the screen question deserves to sit alongside those structural factors rather than below them, especially given the scale of exposure and the developmental windows at stake.
The honest reading of the evidence is this: quality early intervention works, and we should fund and expand it. The researchers are right about that, and the program outcomes are worth taking seriously. But intervention is response. Prevention requires asking what changed.
A quarter of children arriving at school already behind is not an inevitable baseline. It is a signal. Understanding it fully means following it to the places that are harder to talk about, including the glowing rectangle that has become the default babysitter for a generation of children at the most neurologically sensitive period of their lives.

Frequently Asked Questions
What does developmentally vulnerable mean for a child starting school?
A child classified as developmentally vulnerable is missing key skills in one or more domains — language, self-regulation, physical health, social competence, or emotional maturity — that are necessary for learning to take hold. In Australia, one in four children arrives at school in this condition, measured through the Australian Early Development Census.
Do early childhood intervention programs actually work?
The evidence from a University of Melbourne program running across Victorian and Queensland childcare sites shows they can. Children referred by child protection and community health services recorded an average 11.6-point gain in resilience and self-regulation scores within a year, alongside improvements in language and IQ. The children involved had significant exposure to trauma and disadvantage, making the results more meaningful, not less.
Does screen time cause developmental delays in babies and toddlers?
The research is not yet definitive, but it is no longer thin. A growing body of peer-reviewed literature links heavy screen exposure in children under two with delays in language acquisition, reduced attention capacity, and weaker social-emotional development — the same domains measured in developmental vulnerability assessments. The proposed mechanism is that screens displace the slow, reciprocal face-to-face interaction through which these capacities are built.
How many Australian children exceed screen time guidelines?
ABS data shows nearly three in four Australian children aged five to seventeen regularly exceed the government's recommended two-hour daily limit for recreational screen time. The data covers school-age children, but device exposure typically begins well before school age.
Why is poverty not enough to explain rising developmental vulnerability in Australian children?
Poverty and family stress are significant contributors to developmental vulnerability, but they are long-standing conditions that cannot by themselves explain a trend. What has changed sharply in recent years is the screen environment that infants and toddlers are growing up in — a universal shift that cuts across income levels and that coincides with the developmental windows most sensitive to disruption.
