Rate of Improvement (ROI) scores

The Rate of Improvement (ROI) score can be found in the downloadable .csv files that are available once you’ve begun testing students.

To export data, login to your account and go to the “Reports” section. Next choose the “Groups” tab. To the right of each group name is a link to do a "Data Export" by exporting a .csv file. Choose the group whose data you want to export and an Excel file in the .csv format will be downloaded to your desktop. A .csv format means a document has no formatting associated with it.

The ROI used for easyCBM is calculated based on the formula mandated by the state of TN (where teachers must provide ROI information for every student being progress monitored / provided Tier 3 instruction). It is not a linear regression method.

The formula is fairly simple. We subtract the students’ most recent prior score from their current score and then divide by the number of days in between the two scores. As a student takes additional assessments, the ROI is updated to reflect, always, the change over time (‘rate’) from one score / assessment to the next.

The Rate of Improvement is a simple computation based on change in score / # of days between testing sessions. When developing instructional goals, however, we encourage you to refer to the national norms, and to set goals based on having students meet or exceed the 50th percentile on those on-grade norms for the various measures. The raw score associated with the 50th percentile varies by measure and season, so using the percentile lines displayed on the Individual Reports can provide a nice referent as well (you can set the ‘target’ goals for these lines through your Account —> Systems Settings page.
