text: My third reason is that community service takes too long after school. When the average student gets home, all they usually think about is getting away from the stress at school. They don't want to get more work to worry about. Community service also might intrude on their sleep time too. If a student does community service right after school, they would then have to do their homework, sometimes students barely make it to bed with homework alone. If you threw in community service on top of that, image how little sleep students would get.
