Using Data to Improve Student Achievement

The Data Quality Campaign and the National Center for Educational Accountability (NCEA):

conducted a survey in September 2007, with the support of the Bill & Melinda Gates Foundation, about state data systems to determine the number of states that have built the infrastructure to tap into the power of longitudinal data. Similar surveys were conducted by NCEA in 2003, 2004, 2005 and 2006. This website provides an overview of the findings of the survey in addition to a state-by-state analysis of the policy implications of each state's data system.

The Power of Longitudinal Data
Longitudinal data matches individual student records over time, from pre-kindergarten through 12th grade and into post secondary education. States are spending hundreds of millions of dollars to improve student achievement. But without quality data, they are essentially flying blind. Policymakers need to act now to put in place the policies and resources to ensure that each state has a longitudinal data system and the culture and capacity to translate the information into specific action steps to improve student achievement. When states collect the most relevant data and are able to match individual student records over time, they can answer the questions that are at the core of educational effectiveness. Longitudinal data (data gathered on the same student from year to year) makes it possible to:

State specific results.
