Early Development Index (EDI) & Parent Toolkit

First 5 Orange County partners with the UCLA Center for Healthier Children, families, and school districts to gather and analyze EDI data. The EDI has been tested internationally and found to be a reliable indicator of children’s readiness for kindergarten.

The following map is a snapshot of children’s early development in our region of Orange County using 2022 EDI data.
