My son turned 18 last year (9/27/15) we live in PA (Butler County) and he is a Senior. He has missed 10 days of school some excused some not and has also left school early and arrived late, again some with notes and some not. He seems to think that being 18 it does not matter how much he misses and that nothing can be done to him. I am afraid I will be charged with turancy or worse. With him being 18 what are the laws or requirements and what can happen?
