Before a group can take attendance, its group type must first be configured to enable attendance tracking under Admin Tools > Settings > General > Group Types. From here you should select the group type you'd like to configure check-in for. Under the Attendance / Check-in tab enable the setting Takes Attendance. While this one setting is all you need to enable the attendance features, there are a couple of other settings that help improve the attendance tools: Group Schedule Options: While a group schedule is not required to take attendance, having a schedule will simplify the attendance entry because it will guide the user to enter attendance on those dates when the group meets.Schedule Exclusions: While each group can set its own schedule (including exclusion dates) you may want to set exclusion dates for every group of this type. This is especially helpful when using the simple schedule option where you only specify the day of the week and the start time for a group. Adding these group type schedule exclusions helps to keep email attendance reminders from being sent.Send Attendance Reminder: This checkbox will enable the sending of an attendance reminder email or text message to the group leader the day the group is scheduled to meet.
