It is not a substitute for professional assessment, diagnosis, or individualised advice from a qualified health professional. Families with concerns about their child’s development are encouraged to consult a qualified occupational therapist, GP, or other appropriate health professional for guidance specific to their child’s needs.

Every parent watches their child grow with a mix of wonder and quiet worry. When a child seems to be developing differently from others their age – perhaps not yet walking, struggling with speech, or finding everyday tasks unexpectedly difficult – those quiet worries can become overwhelming. Knowing where to turn, and when, is one of the most important things a parent can do.

OT screening for developmental delays offers a structured, evidence-based pathway to early answers. When carried out by a qualified occupational therapist, this process identifies areas where a child may benefit from support – and, crucially, connects families with the right services before delays compound over time.

According to the Royal Australian College of General Practitioners (RACGP), more than one in five Australian children are developmentally vulnerable in at least one domain, and at five years of age, one in five children is described as developmentally vulnerable. These are significant figures – and they highlight why understanding OT screening for developmental delays is not simply useful, but essential knowledge for families across Brisbane, North Lakes, the Gold Coast, the Sunshine Coast, Sydney, Melbourne, and beyond.


What Is OT Screening for Developmental Delays, and Why Does Early Identification Matter?

Developmental milestones are the skills most children acquire within certain age ranges – smiling, rolling, sitting, walking, talking, and playing with others. While every child develops at their own pace, consistent delays across one or more developmental areas can indicate that professional evaluation is warranted.

OT screening for developmental delays is a structured process conducted by an occupational therapist to assess whether a child’s development aligns with expected milestones across key domains. Unlike a formal diagnostic assessment, a developmental screening is typically a briefer evaluation designed to determine whether further assessment or early intervention support would be beneficial.

Early identification matters profoundly. Research suggests that children who access early intervention may make considerably stronger progress than those who do not. The critical windows of early childhood – when the brain is most receptive to learning – mean that timely support may help set a stronger foundation for a child’s future independence, communication, learning, and social participation. Studies indicate that between 75 and 95 percent of children who receive early intervention make excellent progress, with benefits including improved communication, adaptive skills, more inclusive education placements, and prevention of secondary health and psychosocial complications. Families are encouraged to consult a qualified health professional to understand what this may mean for their individual child.

Longitudinal research, including the Perry Preschool Project, the Chicago Child and Parent Centers, and the UK EPPE study, confirms that early childhood intervention is associated with measurable improvements in educational outcomes, health and wellbeing into adulthood, and reduced need for more costly interventions later in life.


What Are the Key Warning Signs of Developmental Delay Across Different Ages?

Identifying developmental red flags at various stages can help determine when professional guidance might be needed.

Birth to 6 Months

Warning signs include lack of babbling sounds, not reaching for or holding toys, not responding to sounds, or insufficient head control when pulled to a sitting position. Persistent asymmetrical movement patterns and feeding difficulties are also signals to consult a health professional.

6 to 12 Months

Parents should consider seeking guidance if a child does not pass toys from hand to hand, isn’t beginning to move around, is not taking weight on legs when held in a standing position, or fails to respond to familiar words such as their name. By twelve months, a child who does not search for hidden objects, wave, or point may benefit from professional evaluation.

12 Months to 3 Years

Red flags during this period include not walking by 18 months, having fewer than five words by 18 months, not following simple instructions, not engaging in pretend play, and difficulties with transitions or emotional regulation. Any regression – the loss of previously acquired skills – is a signal that prompt referral may be warranted.

Self-Care, Sensory and Social Concerns

In addition to motor milestones, concerns regarding dressing, feeding, toileting, sleep, extreme responses to sensory input, or challenges with peer play and social cues should be discussed with a qualified health professional.


What Does an OT Developmental Screening Actually Involve?

OT screening is typically carried out in a familiar environment, such as the family home or childcare setting. Here’s what to expect:

Before the Screening: Parents complete questionnaires about their child’s developmental history and current concerns. Any previous assessments are reviewed if available.

During the Screening: Lasting around 30–40 minutes (with comprehensive assessments taking up to two hours), the occupational therapist observes the child during everyday activities, assessing areas such as fine and gross motor skills, visual and auditory skills, attention, sensory processing, play, social participation, and self-care abilities. Parental input is crucial throughout this process.

After the Screening: A report is provided with observations and recommendations. If concerns are identified, families receive guidance on next steps, which may include further assessments or referrals.

Screening results are not a formal diagnosis; they serve to indicate areas where further evaluation may be beneficial. For families in regional or remote areas, or those preferring flexibility, telehealth options are available across Queensland, New South Wales, Victoria, and Tasmania.


Which Standardised Tools Do Occupational Therapists Use for Developmental Screening?

Occupational therapists use evidence-based, standardised tools to guide the screening process. Some commonly used instruments include:

  • Ages and Stages Questionnaire (ASQ-3): For children 1–66 months, assessing communication, motor, personal-social, and problem-solving skills.
  • ASQ-TRAK: Culturally adapted for Aboriginal and Torres Strait Islander children, for ages 2 months to 5.5 years.
  • Parents’ Evaluation of Developmental Status (PEDS): A brief parent interview covering language, development, behaviour, and social interaction for ages Birth–8 years.
  • Bayley Scales of Infant & Toddler Development (Bayley-4): For children 16 days–42 months, assessing cognitive, motor, language, social-emotional, and adaptive skills.
  • Peabody Developmental Motor Scales (PDMS-2): For children Birth–5 years, evaluating gross and fine motor skills.
  • Sensory Profile 2 and Sensory Processing Measure (SPM-2): For assessing sensory processing abilities across various environments.
  • Denver Developmental Screening Test II (Denver-II): For children Birth–6 years, assessing personal-social, motor, language, and adaptive skills.
  • First STEP Screening Test: Covering cognition, communication, physical, social, emotional, and adaptive skills for preschoolers.

These tools are designed to be brief screenings rather than comprehensive diagnostic instruments. They help identify children who may benefit from more in-depth assessments.


How Does the NDIS Support OT Screening and Early Childhood Intervention?

For families with children under nine years, the National Disability Insurance Scheme (NDIS) supports early childhood intervention services through the Early Childhood Approach. OT screening is a central component of this pathway.

Occupational therapists work closely with families to assess developmental concerns, observe the child in familiar settings, and use screening tools to determine eligibility for NDIS funding. Children who show delays, even if not meeting formal thresholds, may still access early supports designed to prevent further developmental challenges.

Mobile and telehealth OT services ensure that families in diverse regions—including Brisbane, North Lakes, the Gold Coast, the Sunshine Coast, Sydney, Melbourne, and various regional areas—can access screening and support in a timely manner.


When Should Parents Seek OT Screening for Developmental Delays in 2026?

There is no single “right” moment, but consider OT screening if:

  • There are concerns about your child’s development in any area.
  • The child is not meeting expected developmental milestones.
  • There is a regression or loss of previously acquired skills.
  • There is a family history of developmental delays, or complications at birth are present.
  • Multiple developmental areas seem affected, or if teachers and childcare providers have raised concerns.

Australia’s Medicare system funds developmental health assessments at 12, 24, and 48–60 months, but parents do not need to wait for these scheduled check-ups. Trust your instincts and seek guidance at the first sign of concern.


Understanding Your Child’s Developmental Journey: What Comes Next

OT screening is about understanding a child’s unique profile and identifying where additional support might be needed. Following screening, families receive a report outlining observations and recommendations. Early intervention can support improvements in fine motor skills, sensory processing, self-care, social participation, play skills, and emotional regulation.

Timely support following early identification can lead to better long-term outcomes. Whether through traditional in-person sessions, mobile services, or telehealth, early OT screening paves the way for tailored interventions that meet your child’s specific needs.

What is the difference between an OT developmental screening and a full developmental assessment?

An OT developmental screening is a brief evaluation – typically around 30–40 minutes – designed to determine whether a child’s development aligns with typical milestones and if further, more in-depth evaluation is needed. A full developmental assessment is a comprehensive process that delves deeper into specific areas of concern, usually lasting longer and guiding eligibility for interventions such as the NDIS. Neither provides a formal diagnosis on its own, so professional advice is essential.

At what age should I consider OT screening for developmental delays?

OT screening for developmental delays can be considered from birth onward. Screening instruments like the Bayley-4 are designed for children as young as 16 days old, and many tools cover children up to five or six years of age. If you notice concerns at any stage – whether as a newborn, toddler, or preschooler – it’s advisable to consult a health professional without waiting for scheduled check-ups.

Can OT screening for developmental delays be accessed via telehealth in Queensland, New South Wales, Victoria, or Tasmania?

Yes, telehealth options are available for OT screening across many parts of Queensland, New South Wales, Victoria, and Tasmania. While some aspects of the screening may be more effectively conducted in person – especially for very young children – telehealth allows occupational therapists to gather developmental history, conduct parent interviews, and offer guidance remotely, making services more accessible in regional or remote areas.

Does my child need a GP referral for an OT developmental screening?

In most cases, a GP referral is not required for private occupational therapy screening, meaning parents can self-refer. However, if you are seeking Medicare-funded assessments or accessing certain NDIS pathways, a referral from a GP or child health nurse might be necessary. It’s best to discuss your specific circumstances with both your GP and the occupational therapy service.

What should I bring or prepare for my child’s OT developmental screening?

Parents are typically asked to complete pre-assessment questionnaires detailing the child’s developmental history and current concerns. It is useful to have any previous assessment reports, letters from other health professionals, or relevant medical records on hand. Since screenings usually occur in a familiar environment like the home, no special preparations of the space are required.
