This document summarises key findings and recommendations from an analysis of Australian Early Development Census (AEDC) data conducted by the Australian Education Research Organisation (AERO) in 2022. AERO's report marks the first time that the skills considered through the Language and Cognitive Skills (school-based) domain in AEDC have been mapped to the Australian Curriculum and National Literacy and Numeracy Learning Progressions (NLNLP), opening up new possibilities for teachers. This new work enables teachers to identify, when an individual child has not yet achieved a skill in that AEDC domain, where that skill is relevant to the curriculum or NLNLP, and decide where next to focus their teaching. Foundation-year teachers can use the accompanying skillmap to look forward, and see the intermediate steps to teach, to support the child to reach the next step. The report also links AEDC data with NAPLAN Reading, Writing and Numeracy data to Year 5, using a national sample, to reveal the building blocks of future academic achievement in schooling.
