John Thompson on data-driven accountability:
Data-DRIVEN accountability makes sense for enforcing the Voting Rights Act, fighting Medicaid fraud, or a war on other criminal conspiracies. It also makes sense when numbers have been proven to reflect physical reality or numbers are used to make sure that other numbers are accurate. Data-DRIVEN accountability is appropriate for deterring threats to society, but to improve teaching and learning we need data-INFORMED accountability and evidenced-based decision-making. We need accountability devised "with teachers" not done "to teachers."
