Effects of the Implementation of Proposition 227 on the Education of English Learners, K-12: 2002 Report

By Tom Parrish, Robert Linquanti, Amy Merickel, Heather E. Quick, Jennifer Laird, Phil Esra


This ongoing evaluation, conducted by WestEd and the American Institutes for Research, is the largest and most comprehensive study of Proposition 227.

This five-year, legislatively mandated study focuses on the effects of Proposition 227, which requires that English learners be taught overwhelmingly in English through immersion programs not normally expected to exceed one year, and permits bilingual instruction only through the granting of a special waiver.

This Year 2 report analyzes the academic achievement of over 1 million of California’s English learner students and another 3 million English-fluent students—utilizing for the first time individual student data.

It also analyzes surveys of hundreds of California teachers and school and district administrators.
