I use this in my classroom to monitor attendance and behavior. Each student has a clothespin with their name on it. If students leave the room for the bathroom or nurse they move their clip to show they are out of the room. And, if their behavior needs redirection, they can move to yellow or red. It works really well during a fire drill...just grab the chart and go with a full record of who is where. At the end of class I record this information electronically for my files.
