EDI
The Early Development Instrument (EDI) was developed by Magdalena Janus and Dan Offord and released in 2000. It assesses community outcomes in child development in respect to health, learning, and behaviour. The validity and reliability of the EDI continue to be monitored on an ongoing basis. Analyses demonstrate that its structure is robust and validity meets acceptable psychometric standards.
The EDI data are collected for individual children, and EDI scores correlate reliably with other similar measures of child development. They are also predictive of later outcomes including academic achievement in primary school. However, the EDI is not designed to be a tool to diagnose individual delays or developmental problems.
The EDI’s strength is allowing the aggregation of individual data to the group or community level, which makes it possible to integrate child development outcomes with other sources of data about children, families and communities.
