A Florida mom is forcing her son to stand on a Tampa Bay street corner this week and wear a sign to tell drivers about his poor school grades.

With his mother watching nearby, James Holder, 15, wears a sign that reads “I did four questions on my FCAT and said I wasn't going to do it…GPA 1.22…honk if I need education."

The mother, Ronda Holder, told MyFoxTampaBay.com that nothing has worked yet to improve her son’s grades, including taking his cell phone away.

"Until he straightens up his grades and gets his education on track, he's going to work that corner," she said.

She added that she hoped other parents would take notice of her son and not have to worry about their own children doing the same thing.
