In this report, The Education Trust-West grades the 146 largest unified school districts in California on four key indicators of student performance to see how well they are serving their African-American, Latino, and low-income students. While most districts in California earn Cs and Ds on these indicators, some districts prove that more is possible. The grades and rankings in this report surface examples of higher-poverty districts that are achieving strong results, recording rapid gains in achievement, preventing large gaps from separating student subgroups, and preparing students for college eligibility. These districts and their results are cause for hope and can provide lessons for local, district, and state education leaders. Appended are: (1) Methodology; and (2) Report Cards for All Districts. (Contains 8 tables, 6 figures and 9 notes.)
