Ethnic Diversity Index

The Ethnic Diversity Index (EDI), developed by EdSource, measures how much variety, or diversity, a school or district has among the seven ethnic categories of students reported to the CDE. Numbers close to 100 indicate a fairly even distribution, while numbers closer to 0 mean that students are predominantly from a single ethnic group.
