They were very slow and weak about responding, but you're overstating. They did a few things over the three years, up to and including finally bumping the child back to 9th grade.

The mother apparently did exactly nothing. Until the school's actions finally hit home hard enough.

The headline literally says "ranks near top half of class with 0.13 GPA". So it is not an isolated incident. That is a lot of mothers who did exactly nothing

Maybe? I don't know.

My complaint is with your misuse of language to make a point. "Exactly nothing" means beyond zero is excluded. At worst you need to use "essentially nothing" or some such vague/weasel words rather than stating logical falsehoods.
