Read the story. The mother of the student is working 3 jobs. She is a taxpayer. Presumably she is not asking for free stuff, merely asking the public school system to do the job she pays taxes for.
If she had talked to a teacher or looked at report card or something in 4 years,3 jobs or not she would have seen the problem...Bottom line, if the school has chosen not to do their job,a parent has to step in ..She had no idea until 4 years into this ,that there was a problem....
