Report: States have unused student learning data

Overall, states have made unprecedented progress in collecting longitudinal student data. But they don't actually use it to improve student learning. The analysis also found that the majority of states don't link data across education systems or make it available to stakeholders. Because they don't make it available to stakeholders, they can't make decisions based on the data to help improve student outcomes.
