WRONG. It is the parents' and the student's fault. The student is responsible for their education.
At the core, you are correct. If each student had parents who made sure their child was learning what he needed to know, there wouldn’t be that problem.
But most parents aren’t that aware. They see the report cards and see A’s and B’s and think that little Johnny and Suzie are doing just fine.
Johnny and Suzie don’t feel they are falling behind because they are doing as well as everyone else.
So how is an average parent, who sees A’s and B’s and whose kids don’t think they are falling behind, supposed to realize what a failure their child’s education is?
