Think about whether or not the teacher takes roll. It is best to know which teachers do and don’t take roll in their classes. It is easier to skip classes where the teacher does not take roll because you are far less likely to get caught. If they do, you could try to sneak out of class after being counted present for attendance. Also consider what your teacher is like. It is easier to skip classes that are taught by more relaxed teachers. Never skip a class taught by a teacher who is likely to look for you or ask after you.
Think about why you want to skip and decide if there is a better way to accomplish what you want to do. For example, if you want to skip class because you forgot to do your homework that is due today, maybe you could talk to your teacher instead and convince them to give you an extension. That way, there is less risk involved for you.
To excuse yourself from class a few minutes before the bell, tell the teacher that you have a music lesson/sports practice, that you need to go and take medication, or that you desperately need to use the bathroom.
If you think it’s possible that your parents might drive by the school parking lot during the day to make sure your car is there, it might be a better idea to park at school and just walk somewhere when you skip class. That way, your car will still be at school when your parents check up on you.
You were just running an errand for a teacher. You were on your way to the bathroom. You left your schoolbag/homework in your locker. You’re on your way to/back from the nurse. You’re new to the school and can’t figure out the way to your class. (This excuse is most effective at the beginning of the school year). If you get caught wandering around, pretend to go back to class and go to the nearest bathroom for the rest of the period.
