Though we don't have a report for exclusively that information, we do have a report that includes it. The report is titled "Student Body Diversity" and it can be accessed by following these steps:
  1. Start from any product dashboard and in the Reports tile, click View All (if starting from the onBoard dashboard, select Reports from the Analyze drop down)
  2. From the Category drop down, select User Management -- Student Reports
  3. Next to the Student Body Diversity report, click Run
  4. From the Run By drop down, select Grade
  5. Click Generate Report
The report that is generated breaks down grade levels by diversity, but at the bottom is a total number of students per grade level. This report can then be exported to an Excel spreadsheet, where the unnecessary information can be deleted and you will be left with just the total numbers.
