Roberto's progress on CBM computation.
Note. Each dot represents Roberto's score on one weekly test. G is the year-end goal, and the diagonal line connecting Roberto's baseline score to G is the goal line, representing where Roberto needs to be any given week to realize the year-end goal. The solid line (T) below the graph shows Roberto's actual rate of progress since the goal was set. The grid below the Roberto's skills profile. Each box represents Roberto's mastery status on one skill for each half-month interval (time correponds to the time label on the graph). An empty box signifies that Roberto did not attempt that skill during that half-month interval; a striped box indicates that Roberto tried that skill during that half-month interval but his performance was substantially below mastery; a checkered box indicates that Roberto tried that skill during that half-month interval and his performance revealed partial mastery; a black box with a dot indicates that Roberto tried that skill during that half-month interval and his performance revealed probable mastery; a black box indicates that Roberto tried that skill during that half-month interval and his performance revealed mastery. So, for A1 (simple addition), Roberto began the year attempting the skill, but his performance did not indicate mastery; in the second half of October, Roberto's performance improved to suggest partial mastery, but after the Thanksgiving break, his performance deteriorated to beginning-of-the-year levels; after the winter break, Roberto's performance improved again to suggest partial mastery, and in the second half of February, Roberto's performance suggested partial mastery. The column of boxes for the second half of September indicates that fewer skills were mastered, compared to the column of boxes for the first half of March. This skills profile corresponds to the increasing graphed scores.
