Get a quick look at attendance types across grades by navigating to the Analysis drop-down menu, selecting Attendance as the data set, breaking it out by By Grade Level, and breaking out the series by By Attendance Type. This shows you which attendance types are most common for every grade level.

Use Pivot Table View to get a different view of the same information (which you can download as well). Set Left to By Grade Level and Left Breakout to By Attendance Type.
