How to understand the AEDC results

Understanding your AEDC results

On each of the five AEDC domains, children receive a score from 0 to 10 which is calculated based on teacher responses to the relevant domain questions for each child. AEDC results are reported as the number and proportion of children who are considered to be 'developmentally on track', 'developmentally at risk' and 'developmentally vulnerable' which is categorised based on cut-offs established using 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.
