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.
