The Power of Longitudinal Data
Laird, Elizabeth
Principal Leadership, v8 n6 p34-37 Feb 2008
To provide educators with the data they need to improve student achievement, states must have more than a series of one-time snapshots of student performance. They need a system that collects high-quality data about how individual students are doing over time, from prekindergarten through 12th grade and into postsecondary education. This information--also known as longitudinal data--makes it possible to: (1) follow students' academic progress as they transition from grade to grade; (2) determine the value and effectiveness of specific schools and programs; (3) identify consistently high-performing schools so that educators and the public can learn from best practices; (4) evaluate the effect of teacher preparation and training programs on student achievement; and (5) focus on preparing a high percentage of students to succeed in rigorous high school courses, postsecondary education, and challenging careers. This article discusses the significance of using longitudinal data to improve instruction and management and to improve student performance.
