Demonstrating Student Growth
The data collected from aimsweb assessments, including the rate of improvement, or ROI, are powerful tools to assess whether your students are making academic progress. ROIs have long been a component of aimsweb reporting, in individual progress monitoring reports and in local and national norm tables.
To make ROIs even more valuable, aimsweb includes Student Growth Percentiles (ROI growth norms). These norms allow schools to evaluate the progress of individual students relative to the rate of growth shown by similar students in a national norm sample.
Student Growth Percentiles
Student Growth Percentiles (ROI growth norms) are percentile norms that indicate the percentage of students in the large, representative national norm sample who had ROIs equal to or smaller than a particular ROI. Because growth rates vary by initial performance level, these norms are most meaningful when the comparison group consists of other students who had a similar level of initial performance. To be able to make such comparisons, five separate sets of Student Growth Percentiles were developed for each grade and time interval (fall-winter, winter-spring, and fall-spring) that correspond to five ranges of initial scores (very low, low, average, high, and very high). Through the use of stratified comparison groups, the aimsweb Student Growth Percentiles can help teachers more accurately interpret each student’s progress and set realistic yet challenging goals.
- Calculate a student’s Rate of Improvement (ROI) relative to the ROIs of other students at the same grade and at a similar level of initial score
- Set meaningful and realistic progress monitoring goals
- Look at the distribution of Student Growth Percentiles at the class, grade, school, and district levels
