Longitudinal data refers to a type of data collection and analysis that tracks individuals, groups, or phenomena over an extended period, often spanning multiple years or even decades. This data collection approach allows researchers and educators to examine trends, changes, and developments over time.
In the context of education, longitudinal data may involve tracking individual students' academic progress and outcomes from kindergarten through high school and into postsecondary education or the workforce.
Longitudinal data can provide valuable insights into educational trajectories, including factors influencing student success, graduation rates, college and career readiness, and the effectiveness of educational interventions.
Educational institutions and policymakers often use longitudinal data to inform decision-making, assess program effectiveness, and develop strategies for improving educational outcomes.
