On October 8, 2011, California Gov. Jerry Brown took a stand. Throughout the 2011 session of the California General Assembly, Senate President Pro Tem Darrell Steinberg had been pushing legislation designed to revamp the state’s system for holding K-12 schools accountable for student success. California’s Academic Performance Index (API) system hadn’t been updated since 1999 and relied mostly on standardized tests of basic proficiency in reading and math. Steinberg’s bill, SB 547, would have changed the system to include graduation rates and measures of career and college readiness.1 The bill passed both the Assembly and Senate by wide margins and with bipartisan support, in addition to the backing of diverse organizations including business groups, charter school operators, and school administrators.
