Smartpass allows five kids into a bathroom with seven stalls at a time at my school. Often times children are over 10th in line to use the bathroom. The solution is simple: after 10 minutes, still mark the student as out of the room to collect data but allow another student to use the bathroom in their place. This makes much more sense as students often forget to end their pass or use a pass to the bathroom as an excuse to walk the halls. Please consider this reccomendation.
