Every year, California public school students in grades 2-11 take Standardized Testing and Reporting, or STAR, tests to assess their progress in English language arts, math and other subjects. Below is a look at how students in Alameda and Contra Costa districts stacked up when compared with students statewide in English language arts and math.

These scores, along with other accountability measurements, will be used to create Academic Performance Index, or API, scores to be released next month. The state is shifting to a new testing system in 2014-15 that will assess students based on new Common Core Curriculum Standards, which are not aligned to the STAR tests.
