The increase in students opting out of standardized tests is a threat to accurately measuring student achievement. This brief examines the effects of opting out in the CORE districts and models how it could affect accountability measures. More opt-outs could significantly impact some metrics, but the growth measure is largely unaffected. Metrics tracking achievement by cohort are at risk of bias, even with low levels of opting out. Adjusting for characteristics of students who take the tests could be a solution.

This brief analyzes the 2018 update of the California School Dashboard, examining improvements and areas for continued enhancement. Using data from the 2019 PACE/USC Rossier poll, the author characterizes use of and support for the Dashboard, finding low use, equity gaps, but high support and preference for the new Dashboard.
