Definition: Longitudinal data represent more than one point in time about an individual, program, or organization.

What This Means: In education, decision makers want to consider not just the status of a school, program, or student, but also the trend. Making progress is valued as well as current high performance. Information systems are being re-engineered to hold data across time and run analyses of trends. A common perspective is to think in terms of annual measures. However, decisions may best be driven by much shorter periodicities.
