The agenda's data-use priority asserts, referencing the field's evidence base rather than a new analysis, that standardized tests "provide biased information about school quality" and that policymakers need alternative metrics. No specific study or effect size is cited in the text.

"Federal policy continues to require that schools be evaluated based on proficiency on standardized tests, despite strong evidence that they provide biased information about school quality—indicating that policymakers need alternative metrics for meeting their goals for measuring school progress."
