For the past 10 years, First 5 Orange County has led the way in collecting Early Development Index (EDI) data from 100% of school district-run elementary schools. In 2025, over 22,000 records were collected from 993 kindergarten teachers across 387 schools. We celebrate a decade of insight!
This population-level data provides a powerful lens into how neighborhoods—not just schools—are preparing children for kindergarten. The EDI continues to be a trusted source for informing local planning, equity reports, and community investments.
