Proposition 227 Final Report

A five-year evaluation of the effects of Proposition 227 on the education of English learners.

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

Executive Summary
Submitted to the California Department of Education
 by American Institutes for Research and WestEd
Findings from a Five-Year Evaluation

In 2000, the California Department of Education contracted with the American Institutes for Research and WestEd to conduct a five-year evaluation of the effects of Proposition 227 on the education of English learners (ELs).   Student achievement analyses, phone interviews, case study site visits, and written surveys were used to examine such questions as how the proposition was implemented, which EL services are most and least effective, and what unintended consequences resulted from Proposition 227 implementation.

Important findings from the achievement analysis include the following:

Because model of instruction does not appear to be a clear determinant of EL success, we explored the premise that the best source for understanding what does lead to high-level academic performance for ELs would be schools and districts that appear to be achieving this result. We developed a model for identifying such sites and interviewed administrators from 66 schools and 5 districts that are among the highest performers statewide. Our findings suggested no single path to academic success among ELs. However, commonly cited key factors included: (1) staff capacity to address EL needs, (2) a school-wide focus on English Language Development and standards-based instruction, (3) shared priorities and expectations in regard to educating ELs, and (4) systematic assessments providing ongoing data to guide EL policy and instruction.

In light of these findings, recommendations from this study include 11 recommendations directed primarily to state and local educational leaders and policymakers.
