Student Growth Percentile and Percentile Growth
Projection/Trajectory Functions
Description
Functions to calculate student growth percentiles and
percentile growth projections/trajectories for students using
large scale, longitudinal assessment data. Functions use
quantile regression to estimate the conditional density
associated with each student's achievement history. Percentile
growth projections/trajectories are calculated using the
coefficient matrices derived from the quantile regression
analyses and specify what percentile growth is required for
students to reach future achievement targets.
