Rate of Improvement (ROI) Display on Individual Student Graph

Rate of Improvement (ROI) is the difference in score calculated between each submission and the earliest dated submission of that grade and type, for each unique combination of grade/measure type. The easyCBM authors define weeks as the number of whole-days difference divided by seven.

Please note that ROI only is calculated within a given grade and measure type, not across grades or different measure types.
