my school doesnt do it but i reckon its a bit invasive... like it really implies a lack of trust in the students, and it seems very unnecessary when there are plenty of other equally viable ways to find out why someone is absent/late. it's not a crime to be away from school if you're sick, or to be late every once in a while. surely they could just wait until you're next at school and get you to hand in a note? or call ahead if you know you'll be away? as for truanters, as if there would be sooo many people doing it that the school feels the need to text the parents of every single person who is more than likely just at home with a headache? geez... oh and, truants aside, if you're away for a genuine reason im pretty sure your parents would know, its not as if they would need reminding of the fact.
