【 摘 要 】

Individual growth curves yield insights about growth that are not available from any other methodology; and, developmental scales based on conjoint measurement models provide unique interpretive advantages for investigations of academic growth. Benefits are demonstrated in three examples. First, a series of fifteen statewide reading growth curves is annotated with historical policy actions related to assessment, accountability and early interventions. Second, a common measurement framework simultaneously addresses five interpretive perspectives - student reading growth; achievement level standards; K-12 text complexity standards; postsecondary reading demands; and, occupational reading demands. Third, incremental velocity norms are introduced for average reading growth based on a parametric mathematical model for individual growth curves.
