The AEDC data are collected by teachers who complete an online checklist for each child in their first
year of formal full - time school (∼ 5
years old) covering the five ECD areas previously noted
of physical development, social competence, emotional maturity, language, and cognitive development (eg, academic learning), and general knowledge and communication.17 Children are scored on each
of these domains, and categorised as «developmentally vulnerable» (≤ 10th centile), «developmentally at risk» (between 10th and
25th centiles) and «developmentally on track» (≥
25th centile) 17 Children who are developmentally at risk on one or more ECD domain (ie, DV1) is typically reported in AEDC
publications.
