From 1999 to 2013, California had a standard test (STAR – Student Testing And Reporting) to assess our students on California Standards in English Language Arts, Math, the Sciences, and Social Sciences. Within its first few years, the test format stabilized, and for the rest of its life, it remained essentially unchanged—regularly releasing a fraction of its items to educate the students and parents about the expectations from our students and offering stable longitudinally comparable scaled scores.
