I don't want to connect 6th-12th graders to an event on Sunday morning, but I'm trying to figure out how our youth pastor can take attendance on Sunday morning.
If you do not want to connect them to the Event, you have a few options:
You could include them in the Headcount for the Event (each individual is not tracked but they are counted towards the total people there for the day)
You could create a Youth Group Small Group and take individual Attendance there. It's not connected to the Event and would show attendance on the individual's timeline.
