text: First, the parent might need to get a-hold of the student during school for something extremely important. Something could have come up like a death or odd news. Another example would be that the student could have left something at home and they decide to text one of their parents to bring it to school for them. One more example would be that there is an unexpected club meeting of some sort that came up that day, so the student should be able to text one of their parents during the free period to let them know that they will be home late and give them a heads up notice. This is one reason why I think the principal should go with policy A.
