California’s Charter School Performance


This second annual analysis of charter school performance in California compared how well charter schools did versus noncharters, as measured by the percentage of schools that met their 2005 Academic Performance Index (API) growth targets. The 20-page report also looks at charter school performance by grade level (elementary, middle, and high schools) and by charter type—start-ups versus conversions; classroom-based versus nonclassroom-based. Moreover, using data from a spring 2005 EdSource survey, it compares the performance of charters by the amount of student instructional time and degree of school autonomy.
