Understanding your AEDC results
AEDC results are reported as average (middle or median) scores (0 is the lowest score; 10 is the highest score) on each of the five AEDC domains. AEDC results are also reported as proportions of children who are considered to be ‘on track’, ‘developmentally at risk’ and ‘developmentally vulnerable’ on each domain which are based on 2009 data.
Children developmentally ‘on track’
Children who score above the 25th percentile (in the top 75 per cent), determined using the cut-off points established in 2009, are classified as ‘on track’.
Children ‘developmentally at risk’
Children who score between the 10th and 25th percentile , determined using the cut-off points established in 2009, are classified as ‘developmentally at risk’.
Children ‘developmentally vulnerable’
Children who score below the 10th percentile (in the lowest 10 per cent), determined using the cut-off points established in 2009, are classified as ‘developmentally vulnerable’. These children demonstrate a much lower than average ability in the developmental competencies in that domain.
How the AEDC groupings are determined
To determine which children fall into these groupings, AEDC cut-offs have been set for each domain based on all children who have participated in the AEDC nationally in 2009 – the national AEDC population. The 2009 cut-off points apply to all future data collections.
Results are reported at the national, state and territory, community and local community level to help create a snapshot of early childhood development.
