You can create an unlimited number of Rollcall Categories, either Standard, Live, AM/PM Registration or REACH Event.

A single rollcall category can be used to generate the Checkin/Rollcall Summary for any day.  This dashboard report aggregates all of the rollcalls taken for the one category into a visual summary. Rollcall Management > Checkin Summary

You can view a students' rollcall history from Dashboards > Boarder Summary, from Student Sidebar > History > Rollcall History, as well as run reports for specific queried fields for rollcalls over a set amount of time using Instant Reports > Boarder Attendance Over Time.
