ABSTRACT Understanding the distribution of achievement levels of students' performance on NAEP is aided through the use of the trilinear chart. This chart is described and its use illustrated with data from the 1992 state NAEP mathematics assessment. It is shown that one can see readily the trends in performance for different demographic groups for all of the 44 participating jurisdictions simultaneously.
