Longitudinal Analyses of Academic Achievement

This is the authors' abstract. We don't add key points for this paper.

Mathematical models of individual growth are the basis for analyzing academic achievement over time. This study demonstrates that much can be learned about academic growth from the analysis of individual growth curves. In addition, we illustrate the aggregation of individual responses to provide descriptions of institutional growth. Although more efficient statistical methods are available, the simple approach taken here serves to demonstrate the logic and approach to analyzing longitudinal data.
