Australia's Thriving Kids Initiative Needs Clearer Measurement Language to Succeed

Australia's Thriving Kids initiative represents a once-in-a-generation opportunity to reshape early childhood intervention (ECI) at scale. The Parliamentary Inquiry Report into the Thriving Kids Initiative ‘No Child Left Behind’ [1] and the subsequent Thriving Kids Advisory Group Final Report [2] together set out an ambitious vision of improved identification of developmental concerns, family centred and strengths-based service systems and better access to supports in the environments where children live, learn and play. This vision is both welcome and well-aligned with contemporary best practice [3]. However, both reports overlook a critical and largely unaddressed risk. Neither addresses how we will know if early intervention or supports are making a meaningful and sustained difference for children and families. Throughout both reports, several fundamentally different ‘measurement’ activities are described. These include developmental screening, assessment, diagnosis, outcome measurement, monitoring and programme evaluation. Each serves a distinct purpose, requires different tools and generates different kinds of information. Yet activities are discussed interchangeably without due acknowledgement of the consequences of conflating them. Distinguishing measurement activities and functions matters. Population-level tools such as the Australian Early Development Census [4] describe patterns of vulnerability across communities. They are valuable for policy planning and resource allocation, but are not designed to guide decisions about individual children or to evaluate whether an intervention has been effective. Screening and assessment tools sit upstream of intervention. Their purpose is to identify potential developmental concerns, understand a child's strengths and support needs and match families with appropriate services. Outcome measures occupy a different conceptual and consequential space. They are used for assessing change over time that may be attributable to an intervention and are central to accountability, service improvement and learning systems. The Thriving Kids Advisory Group Final Report itself illustrates the risk of conflating purpose. It notes that work on the Preschool Outcomes Measure [5] may help educators identify children requiring further support [2]. In education settings, this framing is reasonable, where outcomes often refer to observed competencies to inform pedagogy. In an ECI context, however, this description conflates needs identification with outcome measurement. Measurement tools used to determine support needs are not the same as tools used to determine whether an intervention has led to a meaningful and sustained outcome for a child and family. Treating them as equivalent undermines both purposes. The downstream consequences are significant and far-reaching. Clinicians and educators spend considerable time selecting and interpreting tools without clear guidance on whether they are fit for purpose. Researchers struggle to synthesise findings when tools are used inconsistently across studies and services. Services face difficulties in demonstrating effectiveness, particularly when the chosen tools are insensitive to change. And critically, families experience delayed access to appropriate supports and may also receive services misaligned with their actual needs and desired outcomes. This runs counter to everything the initiative is trying to achieve. The current Thriving Kids design phase is a critical moment to provide clear guidance on measurement tool purpose, selection and use. The challenge is not a shortage of tools. Hundreds already exist across the ECI landscape, and new ones continue to be developed. Currently, there is no systematic, feasible way of understanding the tools that are already available for different purposes, who they are designed for, who can administer them, or how they align with best practice guidelines. What is needed is navigation, not addition. Guidance that maps existing tools to their intended purpose, whether screening, needs assessment, diagnosis, outcome measurement or monitoring and that sets minimum expectations for psychometric properties such as validity, reliability and responsiveness to change, is pivotal. This is particularly pressing for culturally and linguistically diverse communities and Aboriginal and Torres Strait Islander peoples, where culturally responsive measures are required. Guidance is also crucial to support real partnerships with all families, who should have a meaningful role in determining what gets measured and why [3]. A shared measurement language that strengthens accountability and supports learning across the system would give Thriving Kids something Australian ECI has long lacked. A system that focuses on whether children and families are getting the right support at the right time, and whether it is making a genuine difference. The authors have nothing to report.
