(For details, see AIMSweb National Norms Technical Documentation at , under Research Articles and Information on the Resources menu.) The rate of improvement (raw-score points per week) was calculated for each student in the norm sample for each of three intervals: fall winter, winter spring, and fall spring.

3 An ROI Growth percentile indicates the percentage of students in the norm sample with an ROI at or below a given average rate of improvement can differ depending on their initial performance level ( , in the fall for a fall spring ROI). Therefore, the ROI Growth Norms were constructed based on five initial score levels: Very Low ( st 0th percentile), Low ( th 25th percentile), Average (26th 75th percentile), High (76th 90th percentile), and Very High (9 st 99th percentile). The relationship of ROIs to initial score level and time of year (fall winter vs.)

4 Winter spring) is described in the AIMSweb ROI Growth Norms guide , located on the Downloads tab in the AIMSweb find a student s ROI Growth percentile, go to the section for the student s grade and initial score level, and then identify the column for the appropriate interval (fall winter, winter spring, or fall spring). Next, find the student s ROI in the interval column, and then read across that row to find the corresponding ROI Growth percentile. For example, if a Grade 3 student obtains a fall R CBM score at the 23rd percentile (Low), then that student s fall spring ROI of.
