With this in mind we encourage educators to use this reference as a source of information rather than as a prescriptive checklist. A sound understanding of developmental milestones will support you to effectively assess children’s play and learning. Intentional teaching, planning and evaluation should be based on sound professional knowledge. Links to the Early Years Learning Framework (EYLF) outcomes and the National Quality Standards are given as examples. The examples should serve to support you in your reflection about how sound professional knowledge supports your evaluation of the EYLF outcomes. A sound knowledge of developmental information (as well as ongoing professional learning about theories of play and development) will enrich and inform your understanding of and support for the learning and growth of the children in your care. It is our belief that when educators embed the practices and principles of the EYLF into their daily practice, the EYLF outcomes will follow, as will the capacity to meet the National Quality Standards.
