Eighth Grade Math Course Placement by Prior Mathematics Achievement with Reference Line

Kernel density graph illustrating the distribution of prior math achievement (seventh grade CST math score) by eighth grade math course placement (N=3,306 students). Eighth grade math course placement is indicated by the California Standardized Test (CST) exam taken by student in the spring of eighth grade. CST math scale score range = 150 – 600, 150-256 = Far Below Basic, 257-299 = Below Basic, 300-349 = Basic, 350-413 = Proficient, 414-600 = Advanced. Reference line indicated at X=346 (prior CST score of 346).
